Aligning the ECU to your R/C System
Before the Jet-Tronic ECU can be used for the first time, throttle stick and auxiliary
control positions must first be programmed.
To accomplish this, complete the following steps:
1. Connect the two ECU servo cables to the receiver. The “
THR
” cable connects to the
throttle channel and the “
AUX
” cable must be connected to a channel capable of
three (3) positions. Make certain that all other connections are made in accordance
with the
Electrical Connection Diagram
.
2. Inspect the transmitter programming, to ensure that dual rates and exponential
functions are disabled, travel is set at 100% and sub trim is set at zero for both
channels.
3. While pressing the “
Select Menu
” button on the GSU, switch on the receiver.
Helpful hint:
Instead of the
Select Menu
button on the GSU, the small switch on the LED I/O
board may be pressed instead. This button can also be used to advance
through the “
learn R/C
” sequence (described below). This feature is useful when
the GSU is not available. Keep in mind that the LED’s on the I/O board are the
same as the GSU for “
Standby/Manual
”, “
Pump running
” and “
OK
”.
Release
Select Menu
only after the three LED’s display the following blink
sequence:
