Introduction
The Digi One 1A Modem as shown in Figure 20 allows remote dial in access to the ZP3 panel for
diagnostic purposes.
The Modem communicates to the ZP3 panel via the serial port connector JP3 on the ZPAB-RS232
board located on the ZP3 panel. Legacy Modems were additionally controlled via a Modem
Control board connected on the panel’s SSB (serial synchronous bus).
