Cable and Terminal Resistor
2.2.1
Cable
To connect the RS485 (422) unit, use a shielded twist-pair cable. The cable model must be the AWG 26 to 16, and the maximum
tightening torque must be 0.6 Nm (6 kgf•cm). If a cable other than the AWG 26 to 16 is used, normal communication cannot
be assured because the terminal may be imperfectly contacted. It is recommended to insert a cable integrated by the crimping
tool into the terminal.
Total extension distance 50m (No use : max. 500m), max.8 stations.
