ELECTRICAL INSTALLATION OF RECEIVER
The following is the wiring chart for the Receiver to the Logic Box. These color-coded wires
should be wired into the input side of the Logic Box (TB1). The +V (power) and -V (ground) can be wired into TB2.
* The Aux button can be used for Stow, Deploy or Oscillation if available on the monitor. Wire the white/red wire into the
corresponding terminal requested by customer for the appropriate function. See monitor operating instructions (or Logic
Box Lid) for wiring diagram and terminal location.
** Run jumper wire from TB3#7 to TB3#3 to have the Aux LED on the handheld controller indicate if the monitor is
stowed or deployed.
• Aux LED ON - Deployed
• Aux LED OFF - Stowed
SYNCHRONIZE SIT WITH RECEIVER
• Before initial operation can occur, the SIT must be synchronized with the receiver. This establishes
proper communication between the two and ensures that the SIT will only control the operation of one Receiver.
Synchronization is performed only once when the system is put into operation for the first time or if it becomes
desirable to synchronize the Switch Interface Transmitter with a different Receiver.
An unsynchronized SIT will flash all LED’s in unison when it is turned on. New SIT’s are shipped
unsynchronized.
1. Make sure only the intended Receiver module is powered on. The SIT will synchronize with any
Receiver which responds to its request for a serial number. To prevent unwanted synchronization, only
the intended Receiver should be turned on.
2. Power up the SIT. The Receiver to which the SIT will be synchronized can be powered up before or at
the same time as the SIT.
3. The SIT will blink all the Red, Green, and Amber LED’s in unison to indicate that synchronization to a
Receiver is required.
4. Start the synchronization procedure by activating the Fog and Up inputs to the SIT while the three
LED’s are blinking in unison. Each of the two connectors on the SIT has a set of Fog and Up inputs. It
does not matter which set is used to start the synchronization procedure. (To re-synchronize: Hold
FOG
and
UP while powering up. Release FOG and UP after turning power on.)
5. The SIT will respond by blinking the Amber LED several times. This indicates that the SIT is sending
messages to the Receiver and asking for its serial number.
6. The SIT will next flash all LED’s once and if the synchronization is successful, the Amber LED will briefly
flash and the Green LED will come on solid. The SIT is now ready for normal operation.
7. If the synchronization fails, the SIT will return to blinking all three LED’s in unison. Make sure that the
Receiver is powered on and repeat the above procedure starting with number 4.
