Handling Process

Step 1 Verify that the HD displays are connected to the COM9, COM10, and COM11 ports on the telepresence host.

Step 2 If the issue persists, check the HD display IDs. If they are not the same, set them to the same value.

For example, if the left HD display whose ID is 1 can be correctly connected to the telepresence host while the center and right HD displays whose IDs are 2 and 3 cannot, change the IDs of the center and right HD displays to 1.

Step 3 If the issue persists, ensure that the serial cables between the telepresence host and HD displays are securely connected.

Step 4 If the issue persists, replace the serial cables between the telepresence host and HD displays.

Root Cause

Possible Cause:

Serial port settings are incorrect.
The serial ports on the HD displays or telepresence host are faulty.
The serial cables between the HD displays and telepresence host are faulty.
The serial cables between the HD displays and telepresence host are loose.
