LTC 4600 Series Instruction Manual Installation
4.6LTC 4628, LTC 4629 Series Modules for Video + Bosch Biphase Control Code Transmission
4.6.1Indicators / Operation
1.The POWER LED illuminates when AC power is applied to the unit.
2.LTC 4628/60, LTC 4628/50, and LTC 4628/00 units: The VIDEO PRESENT LED illuminates GREEN when a valid video signal is present, or RED if no video is being received. The DATA RECEIVE LED illuminates RED when no data is received, and flashes YELLOW as data is received.
3.LTC 4629/60, LTC 4629/50, and LTC 4629/00 units: The VIDEO OUT LED illuminates GREEN when a valid video signal is present on the
LTC 4628 Series Transmitter, or RED if no video is present. The DATA IN LED illuminates RED if no data is being received on the optical signal, and flashes YELLOW as data is received.
4.6.2Optional Connection
Because of signal amplitude variations and possible EMI/RFI noise interference in the Biphase control data line, the pan/tilt device may operate erratically or intermittently when first connected. If this is the case, add the supplied 120 ohm termination resistor across the data connections of the LTC 4629 fiber optic module located at the controller site.
If the supplied resistor is damaged or lost, any locally obtained conventional 1/4 watt carbon resistor between 100 and 120 ohms will suffice.
