Axis Communications T90B35 W-LED, T90B40 IR-LED manual Volt-free input, TTL input, Telemetry TEL

AXIS T90B Series

Volt-free input:	Non polarity sensitive
	Short circuit = Light on
TTL input:	Orange = TTL +ve
	Purple = TTL -ve (GND)
	0	V = Light on
	3	V = Light off

The telemetry input wires (orange and purple) are soldered together when shipped from the factory to simulate a volt-free input so that the illuminator automatically turns on and off via the photocell. Any remote input or switch should be connected to these wires. Snip the end of the cable and separate the cables to use with remote switch or input.

Under normal operating conditions, a telemetry input will activate the unit only at night provided that the photocell detects low light conditions. However, if the photocell is disabled, a telemetry input will activate the unit regardless of ambient light conditions.

The mode of operation is selected by using the remote control.

The remote input can be used in conjunction with the illuminator in the following ways:

1.TEL — see page 24

2.DIM — see page 25

3.TEL + TIMER — see page 25
