OPERATING INSTRUCTIONS
The Switch Interface Transmitter (SIT) is used to control the monitor and nozzle by sending messages to the Receiver. A
return message from the Receiver is used to control two constant current sources on the SIT.
1. To change the horizontal monitor position toward the right or left:
Activate the proper input, “RIGHT” or “LEFT” respectively, in either connector on the SIT.
2. To change the vertical monitor nozzle position upward or downward:
Activate the proper input, “UP” or “DOWN” respectively, in either connector on the SIT.
3. To change the nozzle pattern toward the straight stream or fog position:
Activate the proper input, “STREAM” or “FOG” respectively, in either connector on the SIT.
4. To initiated a stow or deploy function:
Activate the proper input, “STOW” or “DEPLOY” respectively, in either connector on the SIT.
5. The AUX1 or AUX2 inputs in the gray connector of the SIT in the gray can be used for different functions depending
on the electrical installation of the AUX1 and AUX2 wires from the Receiver into the logic box. (See electrical
installation of Receiver)
6. The LED1 output in the Gray connector of the SIT is driven by the state of the INPUT1 input to the Receiver. (See
electrical installation of Receiver.) It is updated when the SIT is powered up but thereafter only when one of the
inputs to the SIT is active. The LED1 output is a 13mA sinking constant current source. The cathode of an LED can
be connected directly to the LED1 output with the anode connected to the supply voltage.
7. The LED2 output in the Black connector of the SIT is driven by the state of the INPUT2 input to the Receiver. (See
electrical installation of Receiver.) It is updated when the SIT is powered up but thereafter only when one of the
inputs to the SIT is active. The LED2 output is a 13mA sinking constant current source. The cathode of an LED can
be connected directly to the LED2 output with the anode connected to the supply voltage.
