Serial Ports
The workstation board provides two serial ports: an external DB9 serial port and an internal
DH10 serial header. The rear DB9 serial A port is a fully-functional serial port that can support
any standard serial device.
Serial B is an optional port that is accessed through a 9-pin internal DH-10 header. A standard
DH10 to DB9 cable can be used to direct serial B to the rear of a chassis. The serial B interface
follows the standard RS232 pin-out as defined in the following table.
