3.2.1 UDAT / UDAT Power+

For two-connectors UDat and UDat Power+, we can find this board:
1 2
1. By-pass key switch: It bypasses the units which are powered up by the UDat.
2. BUS OUT Quick Connector: It transfers power and communication to the network. Wiring from this BUS OUT connector has to be linked to
BUS IN connector if connected to another UDat / UDat Power+
3. BUS IN Quick Connector: It transfers communication (not power) to the network. Wiring from this BUS IN connector has to be linked to BUS
OUT connector if connected to another UDat / UDat Power+
IMPORTANT: In the last two cases (2 and 3), if the items to be connected need to be powered up, then all the wires (BLACK/RED/SCREEN/WHITE/
BLUE) must be connected and it must be done only in the BUS OUT connector. If they only need to be connected for communications then only
SCREEN/WHITE/BLUE have to be connected (no matter if it is made in BUS IN or BUS OUT connector).
4. RS232 Port: Allows peripheral devices connections. Mainly for service.
5. USB Port: Allows peripheral devices connections. Mainly for service and updating.
6. iButton Reader: Allows identification via iButton
7. Power Connector: IEC Power Socket for 240 VAC or 110 VAC, 50 / 60 Hz. Wiring for this connector must be 3 x 1.5 mm
8. RFID reader: Allows identification via RFID card.
For three-connectors UDat and UDat Power+, we can find this board:
You will see there is another connector (orange colour) and the philosophy is a little bit different and it implies different wiring.
Now BUS IN and BUS OUT are only used for transferring communication and GROUP is used for transferring power and communication to the
elements which are connected to that connector. As a guidance, the wire that is connected to GROUP is the one that is marked with a red arrow.
