Connection

MOBIL TRIG The Mobility trigger uses 2 separate modules:

• an emitter, connected on the computer with a USB-A to micro USB-B cable.
• a receiver, connected to the Medelopt device with a trigger cable and to an external 5V supply (battery, computer, …) with a USB-A to micro USB-B cable.

TRIG BOX USB The Medelopt trigger needs to be connected to the Medelopt device with the trigger connector (in gray) and on the computer that sends the trigger with the included USB-A to mini USB-B cable.

Software Commands

To send a trigger signal to Medelopt, send bytes 0x01, 0x02, 0x03 or 0x04 depending on what trigger value you want.
Python example
To rise AUX 1, send this command :
s.write(struct.pack(‘!B’,1))
