Serial Connection
Diagrams
The serial connector is to the left of the control logic connector as shown below:
Each device requires just two connections for data transmission and reception. Additionally, the
device at each physical end of the wiring requires a termination resistor. The SJ300 has built-in
termination resistors that become part of the circuit when you add a jumper as shown.
TIP:
Each slave device on the serial network must have a unique node address, set by parame-
ter C072. If this is a new application, we recommend connecting one new device at a time and
checking the communications after each addition.
