Hardware Connection Guide
This guide document explains how to prepare the hardware necessary to collect data from various patient monitors using the Vital Recorder program. Please read, prepare, and run in order. If you have any questions or suggestions on product improvement, please contact us using the bulletin board on the homepage.
In addition, this manual is for reference only and our team is not responsible for any part of the connection error. For detailed information, please follow the manual provided by the equipment manufacturer.
Connecting one or two medical devices to a PC and collecting data using the Vital Recorder is very simple to get started. As you become accustomed to connecting devices and programs, it is possible to collect data from 5-6 devices at the same time.
So let's get started.
The Vital Recorder works on Windows operating systems, so you need a computer with a Windows system installed. The Vital Recorder has been tested on 32-bit and 64-bit versions of Windows Vista, 7, 8, 8.1, and 10.
The minimum specification of the computer to operate the Vital Recorder is very low. The lowest system specification that we tested for stable operation was the netbook (MSI U-100) based on the Atom CPU (Intel N330) and we observed a 30% increase in CPU utilization when recording data on the full screen in real time. CPU usage on Intel i3-based computers was less than 5%.
With a laptop, you can prevent the operating room from being crowded. Considering the expense issue, we also recommend the low-cost Windows Tablet. Most tablets have similar specifications so you can choose whatever you like. However, it is recommended that you have a full-size USB port, and if necessary, use a USB hub.
There are two types of serial cable: direct cable and cross cable. Note that this is defined by the connection of the wires inside the cable, so there is no apparent difference.
A direct cable is a cable with internal wires that do not intersect, often called a serial extension cable, if it has 9-pin female/male terminals on each side. Please purchase it in the required length. Below is a link to "3 meters Direct Serial Cable (M/F)" that can be purchased in Korea.
Most medical devices communicate with PCs via direct serial cables, but some medical devices (such as Fresenius Vial Orchestra, Edwards Lifesciences' cardiac output devices) require a cross cable. If you connect a cross cable to a device that requires a direct cable (or vice versa), electrical shorts may occur between the device and the PC, causing malfunction of the device, and rarely explosion or fire. You should always keep this in mind.
Our recommendation is that all cables are only provided with a direct cable, and if you need a cross connection, you can purchase a cross gender as shown below. By fixing the cross gender into the device, you do not have to worry about cable type.
Gender type summary
Since the terminal on the PC side is male, the device side must always be a female port. In case of direct connection, Pin No. 2 and Pin 3 of PC 9-pin serial port (DB-9) are Rx and Tx, respectively. If a cross connection is required, the connection pins are changed to 3 and 2, respectively. The recommended method is to prepare all cables with a direct cable and use an additional gender if necessary.
Gender type (Male/Female)
GE Solar 8000M
Base Primea (Orchestra)
Vigileo, EV1000A, Vigilance, Hemosphere
EV1000 Old Ver.
Serial to USB converter
If your computer does not have a serial port, such as a laptop or tablet PC, use a Serial to USB cable. The Serial to USB converter creates a direct serial port on the computer. There is also a multi-port Serial to USB converter for many serial connections. It is recommended to use 2 or 4 ports serial to USB converter. When you connect this converter to your PC, four COM ports are created in the device manager of the computer, allowing simultaneous data acquisition from four devices via one USB port.
If the USB port is not enough, you can also use a USB hub. It is recommended that you select a USB hub that has a separate power supply.
USB extension cable
You may need a USB extension cable if the distance between the computer and the device is too far. If the distance is less than 10 meters, there is no worry that the signal will be weak. In addition, it is recommended to use products that are shielded from electromagnetic waves.
The following is the total cost to prepare basic supplies (the configuration for acquiring data from four equipments at the same time)
Unit price (KRW)
Total cost (KRW)
4-port converter is recommended
Hub with separate power supply is recommended
Sum: 107,040 KRW
Now, let's connect medical equipment and PC in earnest. Depending on the equipment, you may receive data immediately when you plug in the cable, or you may need to enter the administrator mode and change the settings after entering the password. Fortunately, once you have made the connection, you do not have to touch it again. For safety, be sure to set up the equipment before it is connected to the patient or subject.
The important thing about connecting the equipment is that depending on the equipment, it is necessary to connect with a cross cable instead of a direct serial cable. We will tell you again when the equipment is explained.
GE CARESCAPE B850, B650, B450
“ATEN UC-232A USB serial converter” must be used to connect to the CARESCAPE monitor series (you must use ATEN products only because other USB to serial converters are not recognized by the monitors). Plug this converter into the USB port on the back of the instrument . You can plug it into any of the four USB ports on the back of the monitor.
Then, connect to the PC's serial port (or a common USB serial converter) through a female-to-female null modem (cross gender).
Note: This protocol is called the "GE S5 computer interface", and the GE B40 (9 pin cable with pin 4 removed) and the Datex-Ohmeda S/5 monitor (using female-female null modem gender only) communicate with the same protocol..
GE Solar 8000M
You can connect a direct serial cable to the port labeled "RS-232 1" on the right side of the device. No other special settings are required.
Note: This protocol is called the GE Unity protocol. GE Solar 8000m, Solar 8000i, Dash 3000, 4000 and 5000 use this protocol.
GE Dash 2000/3000/4000
Serial communication is performed through the RJ45 connector on the rear AUX terminal.
Therefore, a cable with a serial cable terminal (DB9F) on one side and a LAN terminal (RJ-45) on the other side is required. The wiring is as follows.
Select “GE :: Dash x000” when adding device in the Vital Recorder program.
Note: This protocol is called the GE Unity protocol. GE Solar 8000m, Solar 8000i, Dash 3000, 4000 and 5000 use this protocol.
GE Dash 2500
Likewise, a direct serial cable is used. Plug it into the “Host Comm Port” on the back.
If communication is not established, set the following in the monitor.
1. Turn the Trim Knob to open the Main Menu
2. Select “other system setting”
3. Select “go to config mode” and select “yes”
4. Enter “2508” and select “done”
5. Device rebooted
6. Turn the Trim Knob to select the “Configuration Menu”
7. Select “other system settings”
8. Select “Config HostComm”
9. Select “remote access” and select “Serial 2”
10. Select “Serial 2 setup” and select “ASCII cmd”, “9600 baud” (default)
11. Select “go to previous menu”
12. Choose “save default changes”
13. Select “exit configuration mode” and select “yes”
14. Device rebooted
Select “GE :: Dash 2500” when adding device in the Vital Recorder program.
Note: This protocol is called the GE Dinamap protocol and is only used with the Dash 2500.
GE TRAM-RAC 4A
Waveform data such as electrocardiogram and arterial pressure can be received through the 15-pin ANALOG OUT port on the back of the Tram-RAC 4A housing of the GE monitor.
This port is not a digital port for the transmission of numerical values, but an analog port that outputs the waveform change as a voltage value. Since the voltage value of the analog port can not be read directly from the computer, it needs an equipment called an analog-to-digital converter (ADC) which converts it to digital.
ADCs range in variety, from low-cost products in the $ 50 range to high-performance products in the thousands of dollars. Currently tested equipment is DataQ's DI-149 and DI-155, which are the cheapest but show sufficient performance for research purposes. The most significant difference between the two products is the difference in voltage resolution. For general monitoring purposes, an inexpensive DI-149 is sufficient, but DI-155 is recommended for electrocardiographic T-wave or P-wave analysis (http://www.dataq.com/products).
After purchasing the ADC, you must create a cable to feed the voltage output from the ANALOG OUT port of the GE TRAM RAC into the ADC input. You can also make this cable yourself, but you can leave it to the cable manufacturer. At the time of order, you should ask for production as below. Connect the 1-15 pin of the GE 15PIN to the corresponding terminal of the ADC
This is the connection of custom made cable to DI-149. If you use DataQ's DI-149 according to the above method, you will need about $100-200 per order, including the cost of customs clearance and shipping, and the cost of customizing the 15-pin adapter.
Recent DATAQ instruments such as DI-1110 have two operation modes (libusb and CDC). When operating in the default libusb mode, it cannot be recognized by the vital recorder. You need to change to CDC mode according to the manufacturer's instructions below.
The last thing to note is that you must connect the cable to the specified connector on the TRAM RAC module to receive the waveform signal correctly. Regardless of which ADC is used, the cable must not be connected to the BP connector (BP2, second left connector) to receive the PLETH waveform from the TRAM RAC. If a cable such as CVP is plugged into BP2, the corresponding waveform is recorded instead of PLETH. PLETH and BP's waves look similar, so it's hard to notice when they're connected incorrectly. The figure below shows this incorrect connection. CVP is written to the PLETH channel and CVP is not displayed properly.
Wrong connection: The CVP Transducer cable is connected from the left to the second BP connector (BP2)
Correct connection: The CVP transducer cable is connected from the left to the third BP connector (BP3)
GE Defib connectors
If the analog port is used for other purposes, you can receive ECG, ABP from the Defib.Sync port on the front panel in the form of voltage. The pin numbers are as follows, and the voltage output value is the same as the Tram-Rac analog port. Purchase a 7-pin DIN cable (or 8-pin DIN cable is also compatible, then cut the middle of the cable and modify it.
Philips Intellivue MP/MX series
The Philips Intellivue patient monitor is capable of serial communication via a MIB port that looks like a LAN port. It does not matter whether it is connected to a central monitor or not.
There are several types of MIB ports as shown below. Please note that labels vary depending on the model.
To connect via MIB port, you need to prepare serial cable to connect RJ-45 terminal 4,5,7 and DB-9 female terminal 5,2,3 respectively. The RJ-45 terminal is connected to the MIB port of the monitor, and the DB-9 female terminal is connected to the PC via USB to Serial Converter.
In case of MX400-550 series, communication is possible via the Advanced Interface Card (however, the MX600-800 series must have a MIB board). In this case, note that the Rx and Tx pins are connected differently.
Next, you need to change the settings of the patient monitor.
Press the "Main Setup" button on the monitor and select "Operation Modes". Then click "Service".
You must enter a password to enter service mode. The default password is 1345. If it fails, please contact the manufacturer.
Then go back to "Main Setup" and you will see a menu called "Hardware" at the bottom. Press and hold this button and set the communication speed to "Fix 115200" for "Data Export 1" and "Data Export 2".
Then click “Interfaces”,
Make sure that the driver for port 01a is “DtOut1”. If it is not DrOut1 (e.g. GM or AGM), click the "Change Driver" button at the bottom of the screen and change it to "DtOut1". The number after DtOut may vary depending on the assigned port.
Changes will not take effect until the monitor is turned off and on.
Note) In case of MP2 and X2 monitor, serial communication is not available and data acquisition is not possible.
Lastly, to extract ETCO2 wave, the following steps are required.
Go to “Main Setup” - “Operating Modes” - “Config”.
Password is “71034”.
Press the setup button on the IntelliBridge EC10 module.
Enter “Setup Device” at the bottom of the monitor.
Go to “Setup Anesth. Machine” - “Device Driver” - “Setup Waves”. You can add any wave you want with the Add button. Select “CO2”, “AWP”.
(If the wrong wave is generated, delete all of waves and reset them by pressing the Add button.)
Go to “Select to change operating mode” - “Monitoring”.
Press “Confirm” button to apply the changes.
Drager Infinity Monitor
This series monitor communicates via module, monitor, or Mini-D cable of X5 or X3 of docking station. Cables can be manufactured as shown below or ordered through distributors. (drager part number 5206441 export protocol cable)
In Vital Recorder, communication is possible by adding an Infinity monitor, and most numeric data can be recorded every 2 seconds, but waveform data cannot be extracted.
For wireless connection between MEKICS device and VR, you need to set up a wireless router first. In this manual, we will guide you on how to set up using the iptime wireless router (Other routers are not much different).
Wireless router settings
Connect the power to the router, open Wi-Fi list on your PC, and connect to the AP named iptime-mini.
Open a web browser and enter 192.168.0.1 in the address bar to set up the router.
The default Login ID and Password is admin.
Go to Advanced Settings - Wireless LAN Management - Wireless Settings/Security menu. Set the network name and password as shown above.
Select ‘WPA2PSK+AES (recommended)’ for the encryption option, uncheck “Broadcast SSID”, and click the Apply button.
The connection to the router will be disconnected since the SSID of the router is changed from iptime_mini to mekics_r7.
Connect to a Hidden Network by entering the SSID (“mekics_r7”) and password. The changed SSID would not show up on the Wi-Fi list since “Broadcast SSID” is unchecked from the previous step.
Open a web browser and enter 192.168.0.1 in the address bar to enter the router setting screen.
If you plan to connect the router to a higher-level network (Internet or hospital network), perform this step. If not, you can skip it.
Go to Advanced Settings - Wireless LAN Management - Wireless Extension Settings menu.
Set the wireless extension method to wireless WAN and input the hotspot SSID and password of the VR to which the MEKICS device connects.
Go to Advanced Settings - System Management - Other Settings menu.
In the wired port function setting, click LAN port and then click the Apply button in the lower right corner.
Connect the router that has been set up with the MP1300 device.
Connect the power supply of the router to the USB port on the back of the device and connect the LAN cable.
Select System - Network, then the setting screen will appear as shown above. Set IP and gateway address.
Except the digits after the last period, the rest digits must be the same as the router IP address (192.168.0 as the example above). Choose a random number between 2 and 255 that is not used by other devices for the last digits.
- IP : 192.168.0.***
- Gateway: 192.168.0.1 (IP address of the router)
Go to System - Network - Central - Mode and select MP601.
On Central settings, enter 192.168.137.1 for Server IP and 6002 for Server Port.
The changed settings will be applied after restarting the device.
To add MP1300 on VitalRecorder for Windows, click “Add Device”, choose MEKICS, and set Port 6002.
Nihon Kohden BSM
After connecting “Null modem (M/F cross gender)” to the serial port on the right side of the device, connect a direct serial cable.
No other settings are required.
(Available in VitalRecorder 126.96.36.199 or later version.)
Drager Anesthesia Machine
Connect the direct serial cable to the COM1 port on the rear panel.
If the anesthesia machine is not connected to the patient monitor, no further setup is required.
However, if the Drager COM1 port is already used to transmit information such as CO2 curve, airway pressure curve, etc., from the anesthesia machine to the patient monitor, the following Y-cable for data peeping should be made and used to extract information without disturbing the existing data communication. In this case, you must select the "Read only mode" option when adding a device in the Vital Recorder program.
GE Datex-Ohmeda Anesthesia Machine
The Datex-Ohmeda anesthesia machine is connected using the 15-pin connector (Female) that comes out when you open the back cover. The 15-pin connector has the same height as the 9-pin connector used for typical serial communications, but it is longer.
Since usual Serial To USB connector has 9 pin male port, we need to make a cable that changes it to 15 pin male connector.
If the anesthesia machine is not connected to the patient monitor, no further setup is required.
However, if the Datex-Ohmeda 15 pin port is already used to transmit information such as CO2 curve, airway pressure curve, etc., from the anesthesia machine to the patient monitor, the following Y-cable for data peeping should be made and used to extract information without disturbing the existing data communication. In this case, you must select the "Read only mode" option when adding a device in the Vital Recorder program.
Note: This protocol is called the GE Ohmeda Serial protocol and is used by Aespire, Aespire View, Aestiva, Avance, Avance CS2, Aisys, Aisys CS2 and Carestation 620/650/650c.
For Flow-i, connect “Null modem (M/F cross gender)” and a direct serial cable to the serial port on the lower right side of the back of the device. (Available in Vital Recorder 188.8.131.52 or later version.)
Edwards Lifesciences EV-1000

TOFscan requires TOF-RS1 (you can purchase this from IDMed). Connect TOF-RS1 cable directly to the USB-Serial-Converter without a gender.
Solutions to Common Problems
Most common problems are related to hardware connections. Program bugs are constantly being fixed, so please let us know on the bulletin board any issues that are not fixed.
Symptom: Vital Recorder does not specify COM port when setting up device.
Device Driver Problems
- Cause: The device driver was not properly installed.
- Diagnostics: Make sure the device's port is visible in Device Manager. If there is a yellow exclamation point on the USB Serial Port device as shown on the left side of the figure below, there is a malfunction of the device or a driver problem. It is normal that the equipment is shown on the port (COM & LPT) as shown on the right.
- Solution: Please download and install driver for serial to USB converter from manufacturer website. If the problem persists, it may be a hardware problem, so please contact the manufacturer's service center.
Connected to the wrong port
- Cause: In the case of a 4-port USB hub, the order of the physical port number and the recognized COM port number may occasionally change.
- Diagnosis and solution: Connect one device at a time, and change the COM port in the Add Device dialog box to recognize it.
Symptom: After the device is connected in the Vital Recorder, the data comes in initially and then drops off every few seconds to several hours.
Hub power shortage problem
- Cause: If you use a USB hub to connect multiple devices, the current available in the PC, the port current may become low.
- Solution: If you are using a USB hub, you must use a separate power supply from the external adapter.
External electrical noise
- Cause: Many electronic devices are used in the operating room such as electrocautery, cardiopulmonary circulator, air warmer, neuromuscular potential monitoring equipment. Current noise from these can interfere with the operation of equipment such as data acquisition computers and ADCs.
- Solution: Use the power supply of the computer for data acquisition separately from the power supply of other equipment. In particular, the power cable of the electrocautery must be separated from the data acquisition computer and USB hub. The connection between the device and the USB port should be as short as possible and use a shielded or twisted cable.
Computer port problem
- Cause: If the device is recognized when the computer port is changed, it is possible that the previously used port is defective. The USB port on the computer may be damaged due to loose contact between the port and the cable, pulling the cable into the port, and so on. In the operating room, if the cable is not securely fastened to the port, the cable is pulled and it is common to break the port of the computer.
- Solution: Change the port on your computer, or use a USB hub to connect the device.
Defective USB cable
- Cause: The USB cable may be stepped on, twisted or pulled, resulting in internal disconnection or broken connectors on the port, resulting in poor contact.
- Remedy: Replace the USB cable.
