3.3 OPERATING PROCEDURE
The control receivers receive control data from the transmitter (i.e. JPD-101,
CTX-800, CCU-100). When the transmitter sends control data with the address
of the receiver, the receiver processes the data and applies the required voltage
to perform the function. For example, when the receiver gets control data with its
address to tilt up, the receiver applies the required voltage on terminal block
TB2, position 2, to energize the motors on the pan and tilt unit to tilt up.
The Model CRX-502 receivers have an expansion board for an additional pan
and tilt unit. If the mother board receives control data with the address of the
expansion board, the mother board sends the data to the expansion board. The
expansion board only receives data if the data contains its address.
The receiver can process the following functions from a transmitter:
•
Pan Left/Pan Right
•
Tilt Up/Tilt Down
•
Zoom In/Zoom Out
• Focus Near/Focus Far
• Control (On/Off) Auxiliary Equipment (AUX 1 and AUX 2)
NOTE
To control the auxiliaries in a receiver, the
address of the mother board must be the
control camera on the transmitter.
The auxiliary contacts on the control receiver can be configured as normally
open or normally closed.
