DIP Switch
Used to set the baud rate, communications stop mode, and Registration Table (4-pin switch).
Baud rate setting
4 Mbits/s (default)
Note: A baud rate of 4 Mbits/s is not supported for branch lines and thus cannot be used for
Slave Units with Cables (i.e., Bit Slave Units).
Communications Power Supply Connector
Connect this connector to a 24-VDC power supply when using Round Cable II, Flat Cable
I, or Flat Cable II cable.
Doing so will supply communications power to the Slave Units and Repeater Units on the
trunk line from the communications connector through the Flat Cable.
Note: Do not connect anything to this connector when using Round Cable I cable.
Communications Connector
Connect the communications cable to this connector.
BS+, BS- (communications power) and BDH, BDL (communications data)
BS+ and BS- are used only when using Round Cable II, Flat Cable I, or Flat Cable II
cable to output the communications power supply connected to the communications
power supply connector.
Note: Open Type Connector (to connect Units to the Cable) can be used to connect to a
terminal block.
