8. Set the P/T SELECT switch on the rear of the receiver according to the pan/tilt voltage
requirements.
PAN/TILT VOLTAGE WARNING: The P/T POWER SELECT switch is set at the factory in the
115/230 VAC position. If your pan/tilt uses 24 VAC, remove the label over the switch and set
the switch for 24 VAC. You will damage a 24 VAC pan/tilt if you operate it at 115/230 VAC.
If you select 24 VAC, the maximum output is 48 VA (supplied by the transformer inside the
receiver); make sure the combined output of your pan/tilt and camera (if it also uses 24 VAC)
does not exceed this output.
9. Connect the pan/tilt controls (up, down, left, right, and common). Refer to Figure 2 for
connection of P/T ground wire.
10. Connect the motorized lens controls (iris, focus, zoom, and common).
11. Connect video.
VIDEO IN comes from the camera.
VIDEO OUT goes to the controller.
If necessary, refer to Table B in the
Wiring Tables
section to determine appropriate coaxial
cable types for video applications.
12. Connect the auxiliary outputs (optional).
AUX 1 is a 5 VDC, 20 mA maximum, open collector output. Use the auxiliary:
• To operate low current relays
• To turn on or off a Pelco window wiper that has TTL circuitry
AUX 2 is a normally open/normally closed (Form C) relay. Relay contacts are rated at 1A
maximum at 24 VDC or .5A maximum at 115 VAC.
13. Double check all wiring connections, and then turn on power.
