When connecting the rear D-Sub cables, be careful to connect the correct cable
to the ports on the rear of the 7800TR-BHP.
3.9.1 7800TR-BHP General Purpose Output Connections
The rear 32 General Purpose Outputs from the tally router are broken out to 48 terminal blocks across
the top of the bulkhead panel. Each GPO has a slide switch below it to select between Wet and Dry
modes (see section 3.8.1). The circuit diagrams for the GPOs in both modes are shown in Figure 3-8
and Figure 3-9.
