EStop Programming Problem

EStop Programming Problem was created by AD
Using the RoboRun utility, I can connect and save configurations to my 2850 controller, however as soon as I change the configuration for the "EStop/Inv Input" from "No Action" to "Causes Emergency Stop" and save the configuration on the controller, the LEDs begin flashing rapidly between two unrecognizable symbols ("=| |" and "| =" if looking sideways). While I am still connected to the controller I can change the configuration back, however if I don't then when I reset the controller it flashes rapidly again and will not re-connect to RobuRun. When I reset the controller it acts like it is automatically going to EStop mode, but with the odd flashing. I then have to re-load the firmware in order to connect again to RoboRun. If instead I set the "EStop/Inv Input" to "No Action" then the controller behaves normally.
I desperately need the EStop function to work and this sounds like a software problem, but what can I do?

It looks like the controller is entering estop immediately after reset. Make sure that the estop input is pulled to 5V if the button is not pressed. Try pulling it to 0V instead if this doesnt fix the problem.

The controller is not connected to anything but power and on powerup the Pin 15 is 5.05 volts and the LEDs are still flashing oddly. I tried grounding pin 15 and the LEDs are still flashing oddly.

we'll take a look but keep in mind that you can always ground the yellow (power control) wire to immediately shut off the controller.
