This device is intended for electronic timer adjustment. It can works with Timer T1 and T10. It is a single purpose device, so the work is very fast and reliable. Just connect it to the timer and adjust what you need. Servos are moving while the deflection is being adjusted by Setuper. So you can measure the deflection by some gauge in adjustment process.
Setuper works as a terminal with LCD screen and buttons. Timer T10 has all values and option menus stored in its memory. Setuper just send a command of pressed button. Then the timer replies with text message, which is directly printed to the Setuper's LCD. This solution has an advantage, if the timer option menu is changed by new firmware, the firmware in Setuper needn't to change.
