COM1, COM2, or LPT1 port does not respond correctly
Try COM2. If it also fails, check Setup configuration and verify that the ports are enabled.
Check if any adapter boards are conflicting with ports. If ports are used by an expansion
card, then on board ports must be turned off in Setup.
Check that cables are connected properly and peripherals are powered ON and
configured properly.
If problem persists, contact MultiTech's Technical Support department (see Chapter 6).
Keyboard does not respond to key strokes
Connect keyboard cable to the left round connector on SBC.
If cable converter is used to connect a large 5-pin DIN to a small 6-PIN PS/2 DIN, check it
(the cable converter) to see if it is defective or the wrong type.
Verify that the keyboard works on a different system.
If problem persists, contact MultiTech's Technical Support department (see Chapter 6).
