View Full Version : Communication error and how to reset it

09-21-2013, 05:31 AM
RS0232 controller issues:
green lights is flashing at 5HZ.
Communication error occurs when the identity button is clicked.
( note: the wiring and PC are working for other RS0232 controllers, we just switch the controller to try to load OS firmware)
test pin 50 is disconnected, green light is off.

Tried to use goto bootloader to factory setting. it is not able to make it work.

By the way, can we reset controller by hardware?

Make sure your baudrate is set to 115200 to reset the controller. The only way to reset the unit is via the Download tool.

The communication is not successful for the only one controller.

The wiring, PC and USB-RS232 converter works for other RS0232 controllers, but it doesn't for the only one new controller. It seems to me that the controller is bad ?

How to make a factory rest?

It sounds like the RS232 is bad.

The only reset is with the Download tool.

Set baudrate to 115200, Specials>Commands>Boot Commands>Goto Boodloader with Factory Settings.
