Physical description

1. "TR" - is the the nearest switch to CAN inputs. This switch should be turned "ON" on the last sensor in the CAN chain. The last sensor in the long chain with the length of more then than 10 meters, terminator should be in "OFF" position.

...

There is a mounting bracket on the the unit. Fix unit by M5 or M6 bolts on the cabinet or the rack profile in front of the door. Glue the white sticker on the door in front of the unit IR sensor. Connect CAN input of the unit by RJ11/RJ12 cable supplied to the CAN input of previous CAN unit or monitoring system. The red LED lights up. Match the TR bus terminators on the attached CAN units. CAN bus terminators TR (position 2 in VT450) should be in the ON state only at the end CAN units port and in Off states (1,2) for all intermediate units. One CAN bus can have not more than 8 CAN units, sensors, and/or another CAN devicesdevice. 

If necessary, connect dry contacts, door sensors, or triggers to the unit.

Connection

...

Click "Configure" and wait. The system starts the CAN bus line survey, display displays the list of connected CAN units and sensors. On the CAN devices, the green LEDs lights light up.

If you will go now to the "System tree", there you will see there new CAN devices and/or new CAN sensors. Wait for a little or renew the tree.

If the survey is reset after click "Configure", it means that the line is not connected (bad cable and/or bad connectors) or not matched terminators on the bus. It is necessary to check and change the status of the line or the TR terminations.
