Printer and PC Interface
Overview
A remote serial printer or personal computer may be connected to TB7 on the FACP main circuit board.
Switch SW3, located on the bottom center of the main circuit board (see Figure 2 on page 13), must be
set to configure terminal block TB7 for the appropriate device. Placing SW3 in the “up” position [RS-
232 PC/Printer] will allow connection for most 40 and 80 column printers and most IBM compatible
personal computers, including laptops. (Placing SW3 in the “down” position [RS485 Terminal Mode]
will allow connection of most Terminal Mode annunciators.)
Caution: Circuit damage may result if a ground fault exists on the control panel. Do not connect a
printer or PC to the control panel if a ground fault exists on the control panel.
Programming
For printer or PC programming instructions, refer to "System Edit" on page 49.
Installation
Remote printers and PCs require 120 VAC, 60 Hz or 240 VAC, 50 Hz primary power.
Installation of a printer or PC requires an interface cable prewired to a DB9F connector (see below).
Connect the interface cable to TB7 on the AFP-100 main circuit board and the attached cable to the
EIA-232 serial port on the printer or PC, as shown below. Use a DB25 adapter if a nine pin connector is
not available on your PC or printer.
For this reason, it is important that there
be no pre-existing ground fault on the control panel. Consult the factory for recommended printers.
