Serial Port Connector
The single-width and double-width rear modules both contain a single
IDC-10 connector, providing the interface for serial ports P1 and P2. P1
can be configured as RS-232, RS-422 (Sony), or RS-422 (EEG), via the
DashBoard interface. P2 operates as RS-232 only. The following image
and table describe the pin mapping from the IDC-10 connector to the
two DB9 connectors that can be used to communicate with ports P1 and
P2:

In RS-232 mode, these ports can be connected directly to a standard PC
serial port with a 9–pin, 3–wire straight serial cable. A ’null modem’ ca-
ble MAY NOT be used for this purpose as it will reverse the connections
of pins 2 and 3.
