12-2 Connection Procedure
12-2-1 When making a connection between a master device and one indicator
Use a shielded twisted pair cable to make a connection.
Connect termination resistors without fail. (100
Ω
to 120
Ω
, 1/2 W to 2 W)
The positions of A and B may be reversed for some master devices. If communication can not be
enabled after connection, check all of the connections.
12-2-2 When making a connection between a master device and multiple indicators
Connect the termination resistor at each
end of the wiring connection.
