2.3.8 Connecting a Cable to the Serial interface (RS232)
If the RS232 interface of the MOBOTIX D12 is to be used for switching external re-
lays (lights, alarm sirens, gates, etc.), evaluating external sensors (light barriers,
etc.) or for data connections (weather station, GSM/GPRS modem, etc.), you need
to install an additional serial cable (similar to the steps in section 2.3.7,
Connecting
Additional CAT5 Cables
) before installing the camera.
Due to the design of the camera, a suitably short connector should be used to en-
sure that the cable cover still fits perfectly without jeopardizing the weatherproof-
ness of the camera.
Please also make sure that the serial cable is thick enough to fill the cable guide
beneath the cable cover so that no water can enter the area beneath.
Section 3.7,
Signal Input/Output (RS232 Interface) , contains more information on the
RS232 interface (pin-out, etc.).
