Making EIA-232 Serial Port Connections

Both EIA-232 serial port connections are made through filtered DE9S female
connectors on the front panel. These ports allow connection to a dumb terminal or
PC using a terminal emulation software package for remote monitoring and control.
One port is in connector J4 and is labeled SERIAL PORT-A, the other port is in
connector J5 and is labeled SERIAL PORT-B. When connecting to these ports, use
a shielded cable EIA-232 direct connect cable with the cable shield connected to
pin 1, see Figure
Figure 2-3. DE9 Connector Detail
The default EIA-232 settings for both serial ports are 9600 baud, no parity, 8 data
bits, 1 stop bit, echo on, ASCII mode, and handshaking disabled.
