A third-party controller, such as AMX or Crestron, can be used to control the
SPM412e. To do this use the translator connection on the rear panel connected
to an infrared output of the controller. The controller must have the correct driver
loaded, which should be configured to output a carrier stripped IR signal, and are
available from the AMX and Crestron web-sites.

SPM 412e Control

Two versions of SPM412e have been made with a slight difference in remote
connector configuration, as follows:

4 pin connector, no switch (older version)

The connection from the touch panel controller and the SPM412e should be
made to the ground and xlate (translate) pins of the 4 way remote connector.

3 pin connector with switch (newer version)

The connection from the touch panel controller and the SPM412e should
be made to the ground and idle high pins of the 3 way remote connector,
with the switch pressed in to allow a translate input.

In either case the data sent to the SPM412e is always the same.

The functions that can be controlled and the related Biamp button numbers are
