RTS UIO-256 Universal 16 Input / 16 Output GPI Interface


RTS UIO-256 Universal 16 Input / 16 Output GPI Interface

Each UIO-256 provides 16 GPI inputs and 16 GPI outputs. The GPI inputs can be set up as remotely controlled key panel keys to activate intercom ports, party lines, GPI outputs, etc. within the intercom system. The GPI outputs are typically assigned for activation from key panel keys. They can be used to control lighting or to key remote transmitters, paging systems, etc. Relays can be assigned to keys via AZedit.

The UIO-256 exchanges control signals with the intercom system via an RS-485 data connection. Multiple UIO-256’s may also be interconnected using a multi drop configuration. Note, the multi-drop configuration requires version 2 of the UIO-256 firmware. GPI inputs are connected via a 50-pin telco connector on the back of the UIO-256. Each input requires =5 to +18 VDC for activation. The positive input and common connections may be provided from a remote source. Or, +18 VDC is supplied at the connector by the UIO- 256, and may be used for input activation, with the user supplying the external switch. UIO-256 Frames are generally mounted in the front of an equipment rack near a Master Controller Breakout Panel for ADAM intercom systems or near the matrix frame for ADAM CS intercom systems. When positioning a UIO-256, consideration should be given to the visibility of the front panel status indicators and access to the reset switch. Also, consider access to the rear

panel for fuse replacement or changes to the DIP switch settings, etc. There are no ventilation requirements
