The Serial Output connector is located on the rear panel of the
benchtop unit (see Figure 2-2 on page 2-2), and inside the wall-mount
unit (Figure 2-6 on page 2-5). The output provides RS-232C serial
communications between the unit and a terminal or a PC running in
terminal emulation mode.
The benchtop connector is a standard 9-pin D connector. For
connection to a serial device, the wallmount cable is wired as shown
in Figure 2-8 on page 2-7. The baud rate can be programmed using
the Comms menu (see page 4-10). The data format is 8 bits, 1 stop bit,
no parity.
