3.7 Printer Connection
The SMX-AUS panel can connect to a printer, whose options can be configured. The basic steps for the connection and configurations are as follows:
1. Make a custom cable.
At the printer side: Connect the cable with a 9-pin D-type RS232 serial connector.
At the panel side: Connect the cable with a 5-pin connector to P19.
2. Connect RS232 terminal to printer.
3. Connect printer’s power supply.
4. Configure printer settings as described in the printer documentation.

Ensure that the printer cable is enclosed in a conduit to protect against any mechanical injury.
3.7.1 Digital Input 1
The fire alarm control panels have a power-limited, supervised digital input circuit. The circuit can be used as
switch input circuit with monitoring for open or short circuit conditions. Shielded cable should be used for all
digital input circuit wired to switch external to the panel.
The EOL resistor (71252) is 4.7 kOhm, 0.5 W. Connect the supplied resistor directly across the input terminals
for unused input.
3.7.2 Digital Input 2
Door MCP will be connected with Digital Input 2 with EOL 4.7 kOhm.
