Active Mode Wiring:

 

Different wiring of the serial cable may be required if a 3rd party device is to share the RS-232 port of the Nurse Call. In this scenario a tap will need to be taken from the serial cable as shown in the image. Note that in the software Passive Mode should be enabled on the TTS-1e > Configuration & Settings > General tab if using this option. The cable required between the Nurse Call system, a Third Party device and the TTS-1nce RS-232 Serial Port should be wired as shown;

Passive Mode Wiring:


The enclosed diagram is indicative. Connection wiring may vary depending on the interfacing hardware. Suitable isolating and buffering should be applied if required. Please consult with other manufacturers to confirm their connection requirements.
