Disruption in communications to an external pod is caused by the pod itself,
by a cable problem, or by a communication problem on the main processor
board. Power for an external pod is supplied from the main processor board
when the board senses that a load is present. If the monitor is not
reporting connection of a Hemo2/4 pod, 12-lead pod or tcpO2/CO2 pod, use
the following test to determine first whether or not the pod is being detected.
Note: Only the Hemo2/4 pod "communicates" with the monitor. The
Hemo2/4 Pod is a digital device, and the HemoMed Pod is an analog
or
device.
Connect a 150Ω ¼W resistor between pins 1 and 3 on the suspect port (see
illustration at left), and check monitor display for a pod connection error
"DEVICE FAILURE ON HEMO CONNECTOR x."
• If no error message displays, the problem is on the main processor
board. Replace the Main Processor PCB Subassembly.
• If error message displays, problem may be in cable, pod, or main
processor board. Replace defective component as required.
If only one input or output on a HEMO2/4 or HemoMed Pod fails to function,
try replacing the sensor or cable. If problem persists, replace the Pod.
