Cables
Cable assemblies, cable and connectors can be obtained from several manufacturers. To avoid
intermittent communications on the network, always connect DO and /DO via the same twisted pair.
Likewise, always connect DI and /DI via the same twisted pair. In addition, always connect both ends
of the cable shielding to their prespective connector housings or shield connection. A connection of 24
volts to data lines will permanently damage the module.
