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.
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-20CM, take out the coaxial cable from the JW-20CM.
While the coaxial cable is connected to the JW-20CM, any electric welding nearby the JW-20CM will
cause the welding current to enter the JW-20CM and may damage part of its circuit pattern.
