the deliberator - wiring

Our system has a hybrid parallel/serial wiring configuration that can accomodate different seating arrangements and different size legislatures (up to 20 members).

The design also permits low-voltage communications between the keypad and the computer using telephone-type wire (Cat 5 cable) with modular connectors.

Basic Configuration
Communications to and from the computer and keypads are made through a spare serial port connected to a RS422 multiplexer that is powered independently by an external 12-volt power supply. In this configuration (recommended), each keypad is connected in parallel to the RS422 box.
 
Alternate Configuration
Up to four keypads may be interconnected to a single port on the RS422 box.
