When power is applied to the receiver, the green PWR LED on the receiver lights.
Whenever the receiver gets a valid Coaxitron control signal, the green CX LED blinks.
RANDOM/AUTO SCANNING
Operation of random and auto scanning depends on whether your transmitter/controller is
communicating with the IRD2000/ERD2200 in standard or extended Coaxitron mode.
Standard Coaxitron
Press the Pan Auto (or Autoscan) key to begin random scanning. In random scan operation the pan/
tilt travels between the limit stops with a random scan period of 0-60 seconds. The pan/tilt then
stops for a random period of 0-60 seconds before starting another random scan period. The
direction the pan/tilt moves when another scan period is started is also randomly determined.
When a pan limit stop is reached, scan direction reverses automatically.
Press the Pan Auto (or Autoscan) key again to start auto scanning. After approximately a half hour
of auto scanning, the pan/tilt switches to random scanning.
To turn off random/auto scanning, press the Pan Man (or Manscan) key.
Extended Coaxitron
Activate random/auto scanning by calling the following presets:
Preset 97 – Random scanning
Preset 98 – Continuous auto scanning–see WARNING below
Preset 99 – Auto scanning with half-hour timeout, after which pan/tilt switches to random
scanning
Preset 96 – Stop scanning
WARNING: Activating preset 98 (continuous auto scanning) reduces the warranty on your
pan/tilt to six months.
AUXILIARY OPERATION
Operation of the two auxiliaries varies depending on the transmitter/controller you are using and
whether it is communicating in standard or extended Coaxitron mode. Refer to your transmitter/
controller manual for the exact key-press sequence required to send an Aux 1 or Aux 2 command.
The following explains how the auxiliaries respond with the different Coaxitron modes.
Standard Coaxitron
When a valid Aux 1 or Aux 2 command is received, the corresponding auxiliary operates momentarily.
Extended Coaxitron
When a valid Aux 1 or Aux 2 command is received, the corresponding auxiliary operates momentarily.
Optional Latching Mode (Extended Coaxitron Only)
– When a valid Aux 3 or Aux 4 command is
received, the corresponding auxiliary performs a latching operation.
NOTE:
Aux 3 operates Aux 1, and Aux 4 operates Aux 2.
