, or 24 Vac pan and tilt units.
Check the label on the inside cover of the CRX-500 unit for the pan
and tilt output voltage.
Models CRX-501 and CRX-510 Receivers control one pan and tilt
unit. The pan and tilt connections are made at terminal block TB2.
Models CRX-502 and CRX-520 Receivers control two pan and tilt
units. These models have two boards in the chassis; a mother board
and an expansion board. Both boards have terminal block TB2.
Connect one pan and tilt to TB2 on the mother board and the other
pan and tilt to TB2 on the expansion board.
Run site-specific cabling from terminal strip TB2 to the pan and tilt
unit. Use Table 2-1 to determine the gauge wire required for the
distance between the pan and tilt unit and the receiver.

NOTE
If a ground connection is required for
the pan and tilt unit, the mounting
screw on the board next to terminal
strip TB2 may be used as a ground
connection.
