UniBus 2 Port RS-232 or RS-485 UART


The UniBus 2 Port UART provides 2 high speed, software configurable, Serial Ports allowing connection of serial peripheral devices.

Up to 4 UniBus UART devices may be connected to an Integriti Security or Access Controller. DIP switch options allow each Port to be configured for RS-232 or RS-485 operation.

The UniBus 2 Port UART is designed for installation within the same

tamper-protected enclosure as its UniBus host module. The UniBus device isconnected directly to the host module or another UniBus device via the UniBus patch cable supplied.

Specific RS-232 cables are available separately for the connection of a computer, modem or other serial devices including the Inner Range GSM modem or Multipath IP STU.
