  • Page 9 The bottom casing part includes four slots for mounting the camera using standard M4 screws. The following methods can be used to mount the Terabee IND-Thermal-90: 1. Front-panel mount using the long M4 screw slots (Figure 4) 2. Back-panel mount using the 2mm ledge on the front side of the camera (Figure 5) The first solution allows for easy surface attachment and rapid evaluation of the camera.

    Select Slave address ● When the IND-Thermal-90 is connected for the first time (from default settings), it is important to match the master network speed to the camera default baud rate (19.2 kbps) and parity (even) and connect to the camera. Afterwards it is possible to update the specific camera connection parameters.
