The unit consists of an IP65 keypad featuring 37 tactile keys, eight of which can be defined by the user and identified by inserting key legends from the rear of the keypad. Incorporated into the units is a four line by twenty character, vacuum fluorescent display. Connection to the control system is via a fibre-optic cable to the Master Controller. The interfacing is handled by dedicated built-in network interface software. The only other connection necessary is for the power supply.
