1. Connect the network cable.

TIMENET consumes under 3W and provides a Class I

POE signature.

2. If your network is NOT POE, then you must also connect the

alternative 12V DC power (24V AC source is also compatible).

3. The amber LED will blink twice and then stay on.

After approximately 30 seconds, the unit will be running and

the green LED will blink with short pulses.

This indicates normal running with no GPS signal lock.

4. Connect the GPS antenna cable supplied with the unit and

ensure that the cable connector is fully screwed on.

5. After a few minutes (assuming the GPS antenna has been

properly mounted and connected) the green LED will switch to

a long pulse, indicating GPS signal lock.

NB: Depending upon the positioning of the antenna with respect

to the view of the sky, it may take longer to gain signal lock.
