1783 Line Output Module
CONFIGURING THE 1783
A block diagram of the 1783 line output module is shown in
Figure 1. Study and refer to the diagram as needed during the
following sections.
CONNECTOR OPTIONS FOR THE 1783 LINE
OUTPUT MODULE
The 1783 line output module can use any of the 1790-series
connector assemblies. The connector assembly wiring is shown
in Table 1. A detailed drawing showing typical output module
connections to external equipment is shown in Figure 2.
