The Dorrough Remote Control RW-100 is now compatible with all models of Dorrough analog and digital meters. Button legends on the top apply to analog meters and legends on the bottom apply to digital meters. Connections to the meters are made through eight-pin mini DIN cables attached to the Alarm/Remote connector on the rear of the meters. The RW-100 is powered by the meter(s) to which it is connected, and contains a micro-controller to interrogate and serialize the switch status. Alarm indicators for up to four meters can be monitored on the RW-100 front panel. In addition, the meter alarm closure feature is also duplicated on the rear panel.
