4.2 Preparing the REB233CBB Module
Follow these steps to setup the REB233CBB Module for correct operation:
1. Check or set the power switch off at the Microcontroller PCB.
2. Insert the two delivered batteries and check for correct polarization.
3. The RF-Shielding of the Radio PCB must be faced to the battery holder of the Microcontroller PCB. Plug in the
Radio PCB header ‘X1’ into the Microcontroller PCB socket ‘Expand 1’.
4. The swivel antennas provided with the REB233CBB Module are tested and approved (see B.3). One antenna
must be mounted on each SMA coaxial connector ‘X2’ and ‘X3’ port of the Radio PCB.
Note, to ensure compliance, the use of any other antenna type is not permitted, see B.3.
