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.
