Section 9: Installing control/monitor
wiring
This section describes how to route wiring associated with the remote control and monitoring of the
NX300 transmitter.
PLanning complete?
1. Make sure you have read and fully understood the control and monitoring options described
in the NX300 Pre-installation Manual before proceeding.
2. Make sure the control/monitor wires are long enough to allow routing through the top of
the transmitter cabinet and down to the exciter panel.
Routing cables
1. Route all remote control/monitor cables to the top of the transmitter (left-hand).
2. Get two ferrite toroids (one each of Nautel Part # LXP44 and LP23) from the ancillary kit.
3. Pass all remote control/monitor cables through the ferrite toroids obtained in Step 2 . If
practical, wires should pass through a minimum of two times (two turns) (see Figure 9.1 on
page 9-2 ). An entrance is provided at the top of the transmitter to accept remote control/
monitor wiring (see Figure 9.2 on page 9-2 ). Position the ferrite toroids just outside, or just
inside, the remote control/monitor entry hole.
4. Route the remote control/monitor cables through the cable entry hole and toward the
remote interface PWB (A11A4) on the exciter panel (see Figure 9.3 on page 9-3 ).
5. With the audio input cables near their destination, cut each wire to the required length and
install connectors, as necessary.
6. If you are using web based control for the transmitter, route an Ethernet cable to the
motherboard (A65U1) on the back of the front door. Connect the Ethernet cable to
connector J1 on the motherboard (see
Figure 9.4 on page 9-4 ). Secure the cable to the
existing cable harness using tyraps provided in the ancillary kit.
