install connectors, as necessary.
7. Connect the control/monitor cable(s) to the appropriate connector(s) shown in Figure 2.7.4 on page
2.7.4 . Secure wires to the existing cabling and to the panel using arrowhead tyraps (Nautel Part #

“Configuring Remote Inputs” on page 2.7.5 to configure the external control input switching
circuits for single-ended (using the transmitter’s 15 V dc supply) or differential (using an external
dc supply).
8. If you are using web based control for the transmitter, route an Ethernet cable to the control/
monitor PWB (A4).
9. If the optional GPS Sync PWB is installed and you wish to synchronize the transmitter’s carrier
signal, install the GPS antenna and cabling in the selected location, then connect the cable to J2 on
the GPS Sync PWB. Secure wires to the existing cabling and to the panel using arrowhead tyraps
(Nautel Part # HT76) in the ancillary kit (see
Figure 2.7.4 on page 2.7.4 to locate tyrap anchor hole
locations). Ensure the GPS Sync PWB is configured for the correct antenna voltage (5 V or 3.3 V, the
Nautel supplied antenna is 3.3 V) see
