Installation and Functional Check 
2.2.3 Connection to network 
If either Cardiocap/5 Network option (N-XNET or N-XDNET) is installed, you can connect the 
Cardiocap/5 to the Datex-Ohmeda Network and iCentral. Use the Monitor-Network cable to connect 
the monitor to the network. 
1. Power off the monitor.  
2. On the rear panel, connect one of the RJ-45 connectors to connector X4 and connect the 
Identification Plug to connector X3. 
3. Connect the other RJ-45 connector to the corresponding Datex-Ohmeda iCentral Network 
connector on the wall box. 
4. Power on the monitor.  
5. Confirm that the network symbol and the “Connected to Network” message are displayed on the 
upper part of the screen. 
 
NOTE: The network symbol does not appear if the battery symbol is displayed. 
2.2.4 Sample gas exhaust connections 
When N2O or volatile anesthetics are used, take precautions against venting these gases into room air. 
Return the sample gas to the patient circuit or connect the sample gas outlet of the monitor to the 
scavenging system.  
CAUTION: Strong scavenging suction may change the operating pressure of the monitor and cause 
inaccurate readings or internal damage. 
2.2.5 Scavenging through the ventilator reservoir 
To scavenge through the ventilator reservoir: 
 
Figure 2-5. Scavenging through ventilator reservoir 
• Connect an exhaust line to the sample gas outlet on the rear panel of the monitor. 
2-5  
						

							
Cardiocap/5 Technical Reference Manual 
• Attach the other end of the line to the ventilator reservoir. Make sure that the reservoir tube 
diameter is at least 2-3 times larger than the exhaust line.  
2.2.6 Scavenging through the anesthesia gas scavenging system 
Anesthesia machines are equipped with an anesthesia gas scavenging system (AGSS), and in some 
machines you can connect the sample gas outlet directly to that. 
For example, connect the sample gas outlet to the Datex-Ohmeda S/5 Avance: 
 
Figure 2-6. Connecting sample gas outlet directly to an anesthesia gas scavenging system 
Note: Refer to the anesthesia machine’s documentation to find out where and how the sample gas 
can be connected.  
2.2.7 Connecting directly to a vacuum scavenging system 
To scavenge through a direct connection: 
1. Connect the exhaust line (733195, 5/pkg) to the sample gas outlet on the monitor.  
2. Connect the exhaust line only to an open scavenging system where gas is removed at room 
pressure. Do not connect the monitor directly to a vacuum scavenging system. 
2-6  
						

							
Installation and Functional Check 
2.2.8 Returning gas to the patient circuit 
In some anesthesia machines, you can return the sample gas to the patient circuit, refer to the 
anesthesia machines manuals. For example, if you use the Datex-Ohmeda S/5 Anesthesia Delivery 
Unit (ADU), connect an optional adapter (881644, 5/pkg) to the patient breathing tubes. 
 
Figure 2-7. Gas return to patient circuit in AS/3 ADU 
2.3 Choosing the location 
The monitor can be placed on a flat surface or hung with the handle from the bed or wall rails. Make 
sure that the surface or rail holds up to at least 13 kg/29 lb.  
WARNING: The monitor or its components should not be used adjacent to or stacked with other 
equipment. If adjacent or stacked use is necessary, the monitor and its components should be 
observed to verify normal operation in the configuration in which it will be used. 
When choosing the location, refer to the EMC guidance in the appendix later in this document. 
2.4 Interfacing 
WARNING: Electrical shock hazard. When you connect equipment to the Cardiocap/5 input and 
output connectors, you are configuring a medical system and are responsible for ensuring that 
the system complies with IEC/EN 60601-1-1 and with local requirements. 
2.4.1 Interfacing a printer 
You can connect a PCL-5 compatible laser printer to the Cardiocap/5 using the Datex-Ohmeda Light 
Monitor–Printer cable. Connect this serial-to-parallel interface cable between the local printer 
connector (X2) and the printer. For ordering details, refer to the Datex-Ohmeda Supplies & 
Accessories Catalog. 
WARNING: Connecting the power supply cord of the printer to the wall socket may cause the 
printer leakage current to exceed the limit specified for medical equipment. Always connect the 
printer to an appropriate isolation transformer.

Cardiocap/5 Technical Reference Manual 
2.4.2 Interfacing a computer 
It is possible to interface a computer to the Cardiocap/5. For further information, please contact your 
authorized GE Healthcare distributor.  
WARNING: Connecting the power supply cord of the computer to the wall socket may cause the 
computer leakage current to exceed the limit specified for medical equipment. Always connect 
the computer to an appropriate separating transformer. 
2.4.3 Interfacing other devices using the analog/digital output connector 
The analog/digital output connector (X1) can be used to interface other devices to the Cardiocap/5.  
Digital outputs 
Defibrillation sync 
The ECG generates the defibrillation sync digital output signal. The signal is set to a high state  
(logic 1:  2.8 to 5.0 VDC ) when activated. After 10 ms, it is set back to a low state  
(logic 0:  0 to 0.8 VDC). The signal is regenerated only after returning to the low state. The delay from 
the R-wave peak to the start of the signal is 35 ms maximum. 
Nurse call 
The nurse call digital output signal is generated by red, yellow, and white alarms. When activated, the 
signal is set to a high state and remains at a high state until the alarm situation is over or the Silence 
Alarms key is pressed. The high state (logic 1) ranges from 2.8 to 5.0 VDC while the low state (logic 0) 
ranges from 0 to 0.8 VDC. The nurse call signal also activates a relay that connects X1 (pins 11 and 12).
