Membrane Keypad (P503)
The Membrane Keypad brings together all the elements required for an effec-
tive man-machine interface in one package thus minimising the time taken to
mount and connect to the rest of the system. The keypad has 37 tactile keys,
eight of which can be defined by the user by inserting key legends from the
rear of the keypad. Incorporated into the keypad is a four line by twenty char-
acter vacuum fluorescent display. Connection to the control system is via a
fibre optic cable to the Motion Coordinator master module or network of mas-
ter modules and membrane keypads. The interfacing to the master is provided
by a built in fibre-optic interface module. The only other connection neces-
sary is a 24 Volts DC power supply input.
The TRIO fibre optic network has been designed to link up to fifteen Motion
Coordinator modules and membrane keypads. Any number of either type of
module can be on the network up to the maximum of fifteen but at least one
must be a Motion Coordinator.
The physical connection of the network takes the form of a ring. The intercon-
nections between nodes being made with fibre optic cable
