Printer Cabling
Printers are not a component of the NCM. However, acceptable
printers are those you can configure to a Lexmark® Proprinter®
emulation mode and have either an available serial connection option
or the ability to connect to the NCM through an RS-232 serial to a
parallel converter.
Notes: Smoke control applications require a printer connection to
the NCM. In this case, use the same Mannesmann Tally PRN-5 that
connects to the IFC. Switch settings are described below;
Figure 13 shows the pinout connections to either Port 2 or Port 3. For
the smoke control application, the baud must be 1200 or lower. (A
higher baud may cause the printer to go offline if the printer buffer
overflows.)
If you are using the Color Printing feature for printing alarms, do not
connect the color printer to the NCM. The printer must be connected
to the OWS for color printing to work. Refer to the Operator
Workstation Technical Bulletin (LIT-636013) for details.
The following printer cable diagrams are typical but may not be exact
for your interface.
To properly configure the printer for the NCM, use the individual
printer instructions as a guide to set the mode and DIP switches to the
configurations shown in Table 16.

Mode RS-232
Polarity No reverse polarity (Typically this setting could change,
depending on the individual computer system and cabling.)
Baud Set to the rate established in DDL. The default is 9600. For
smoke control applications using the Mannesmann Tally
PRN-5, the baud must be 1200.
