Connector

Communication cables should be laid from the master station to the slave station one by one. Multiple wiring from one point or wiring without terminators may cause communication errors.

Joint using a

Arrange total cable length within 1 km.

Arrange branch cable line from a trunk within 400 mm.

Prior to any electric welding around the JW-21MN, take out the coaxial cable from the JW-21MN. While the coaxial cable is connected to the JW-21MN, any electric welding nearby the JW-21MN will cause the welding current to enter the JW-21MN and may damage part of its circuit pattern.
