The LED I/O Board
The LED I/O (
I
nput/
O
utput) board is a connection point for the data bus and a display
for the current status of the ECU. The board should be mounted with the LED’s visible
and the data bus connector accessible for GSU plug-ins. The connector facing
opposite of the LED’s is attached to the ECU. The LED I/O board also features a
pushbutton switch function - to learn your R/C system (when powered up), or for
entering the MANUAL mode (when power is already on). These procedures are
described later.
