CHAPTER 6
Troubleshooting Connections
The Omni Control system assists the user by giving many types of feedback to confirm connections and the quality
of the connection.
At the connection panel, the green LED near the COM port will be steadily illuminated when power and control
are both detected. When power is insufficient to run the system, the light will go out or flash rapidly. When control
is not detected the light will flash alternating every second.
The IC-124 shows twenty-four lights on the face panel that indicate connected I/O panel signals.
•
If signal is sent to a connection panel, but the output device is not connected to receive it, the
corresponding LED will signal red.
•
If the output device is connected the corresponding port LED will signal yellow-orange.
•
If signal is coming into a port from an input, the corresponding port LED will show green in time with the
signal.
•
If an intended output signal responds green, then there is likely a short between the signal and the
ground line on the Med Operate I/O in the device or the panel.
If the system is powered when cards or devices are changed, it can damage the system, but more often causes
loss of needed registration of hardware with the central controller. "Live swapping" hardware can be successful
sometimes, but in the event of a missed registry, systems may not recognize components, or the system may shut
down. If the system is not damaged, usually this sort of issue can be easily rectified by restarting the PCIC.
Sometimes it is also necessary to restart Med-PC or MedTest. In short, the fastest, safest and Med Associates
supported method is to turn off the PCIC before removing or adding cards.
Cleaning
Do not submerge any portion of the device in liquid. Clean the device case using a soft cloth that is dampened
with water and detergent. The device case is usually aluminum or plastic polymer. Should fluids enter the device
internals disconnect power and invert the device to drain. Set the device in a warm dry area to air dry thoroughly
before restoring power.
