PHYSICAL CONNECTIONS
RS-232 Nurse Call Physical Connection
The TTS-1nc allows interfacing to Nurse call systems via RS-232 and supports the TAP protocol. Currently the TTS-1nc supports Rauland
Responder 4 and 5 natively. Two connection modes are supported. Active Mode is supported where the TTS-1nc and Nurse call system
are the only devices used. This provides a fully monitored connection between the Nurse call system and the TTS-1.
Passive mode is supported where existing connections already exist between the Nurse Call system and a third party system. This pro-
vides an unmonitored connection between the Nurse call system and the TTS-1.
