2.3 Connecting the RMC

The sat-nms RMC provides a lot of input/output signals. They all are described in the following chapters. Some applications do not require all ports of the RMC to be cabled.

When connecting and configuring antenna control unit (position sensors and motor drivers), the following sequence of items is recommended:

1. Connect the position sensor, but not the motor driver.
2. Configure the RMC for the correct type of position sensor.
3. Move the antenna a small amount in both directions (you need to command the motor driver directly, e.g. using bridge circuits), verify that the angle changes in the right direction.
4. Enter a calibration offset which lets the RMC show an angle which matches the (roughly) estimated position of the antenna.
5. Now connect the motor driver to the RMC.
6. At the 'Test' page, activate the motor driver outputs for a short time; verify that the antenna moves as expected.
