Recently we moved our MX-55VB with a OSP-10M Control across the building. Once everything was set back up, our DNC-B has stopped working. We've ordered a new cable which arrived today, and still are having issues. Getting the "DNC-B Operation 306" Alarm often. Currently the software and the parameters under the CMPS match, such as the baud-rate, stop bits, etc. But my boss insisted that our IT guy take a look and I have no idea if he changed any parameters under the bit, word, or long word sections. Any help would be appreciated.
