Making Header Connections for Keyboard and
Serial Ports
The platform includes cables that connect to the 486 CPU circuit card. These
cables connect to the keyboard port, bottom center, and the second asynchro-
nous port (COM2), top far right. Locate the two pin header connectors on the CPU
card. Locate the keyboard and COM2 cables inside the platform. Make these con-
nections after the CPU card is installed.
NOTE
:
The COM1 port is hard wired to the faceplate connector.
