11.2 the Intelligent Seating Module.
The ISM module (intelligent Seating Module), is the unit where the actuators and the lights are connected
to. All commands which come from the JSM module concerning seat functions and lights are set into action
by this module. These are outgoing signals.
ISM module
Beside the outgoing signals there are also signals coming into this module. These signals can be inhibit
signals and position signals. These signals are being sent back to the main system. Also errors can be
detected here. They are being send to the display and also stored in the memory of the unit. With the help
of a PC we can read the stored error messages to know what is going on.
