Hardware Installation—Installing the
IFC-1010/2020
DIA-1010 and/or DIA-2020 provide access to the system CPU and the
optional SIB, and an EIA-232 unsupervised printer interface (Figure 28).
When terminal supervision is not required and the terminal
N13
(if present)
has no keyboard, the DIA-1010 and/or DIA-2020 provide an EIA-485
interface, which may be used to connect an LCD-80 (in Terminal mode).

If a supervised CRT-1 or CRT-1 with keyboard has been
installed, this interface cannot be used. TheCCM-1
Communications Converter Module must be employed to
connect the LCD-80 in terminal mode. Refer to the
for details.

Outputs are power-limited, but not supervised or
opto-isolated. Connections must be made with overall
foil/braided-shield twisted paired cable suitable for EIA-232
and EIA-485 applications. The printer must be installed in
the same room as the control panel. Terminate the shield
at the cabinet entrance only.
Plug this DB-25 connector into the RS-232 port of
the PRN-3 printer, or Keltron Printer No. VS4095/5.
