rreffner Posted July 11, 2014 Report Share Posted July 11, 2014 While updating the OS on a V130 the serial port stopped working in the middle of the update. I can no longer communicate with the controller. I am sure there must be a way to do a reset. When I hold the "I" button it asks for a password to continue, wich I don't have. I am curious if anyone else has encountered this. Link to comment Share on other sites More sharing options...
Michael_P Posted July 11, 2014 Report Share Posted July 11, 2014 I have seen a similar condition in the past related to the baud rate setting, Please confirm it is set at 57600. You will need to update the OS of the controller to resolve the condition. For this case you will be placing the controller in Bootstrap mode prior to the update. To perform this task hold down the <I>+<Right Arrow> keys and cycle power to the controller then release. You can confirm the controller is in boot mode by checking the connection through the communication and OS window found in the Connection drop down. You will then proceed with the process of updating the controller. When you reach the point that the OS installation wizard appears and you can select the “Advanced” Select this button and it will open a window for you to select the OS files manually. Select the browse button and then choose the file with the highest number and the most recent date. Then proceed with the download. Please let us know of your results.

rreffner Posted July 11, 2014 Author Report Share Posted July 11, 2014 Thanks for the reply. However, I tried your advice but I still can't establish communications with the 130. I tried 57600 and 115200 baud. Link to comment Share on other sites More sharing options...
Michael_P Posted July 11, 2014 Report Share Posted July 11, 2014 This seems to be a unique condition. You should contact Unitronics Support or the OEM to proceed. Support@unitronics.com Link to comment Share on other sites More sharing options...
Saragani Posted July 13, 2014 Report Share Posted July 13, 2014 Unless changed, the default password for the Info should be 1111 Youl should be able to ener it and see or change the communication settings Link to comment Share on other sites More sharing options...
rreffner Posted July 23, 2014 Author Report Share Posted July 23, 2014 Thanks. That allows me to reset the baud rate and reestablish communications. Every time I try to install the O/S it loses communbication again before the process is complete. Link to comment Share on other sites More sharing options...
