On my DT800 after I use command ?ALL I get alarm details followed by ?? SELF DIAGNOSTIC: "Bad Default" DCOutput.. c 974 I then have trouble with communication to the logger and have to do a hard reset to continue.

I am communicating through the ethernet port and have a GSM modem connected to the serial port. I am using Delogger. What can cause this error.

Good afternoon PRC,

Could you please send me a copy of contents of your DeLogger project sub-directory, the version of DeLogger you are using, The DT800 serial number and Firmware version number?

Cheers,
Roger

Hi PRC,

Your program was written with the DT500 program builder. The language syntax differences between the loggers caused the crash.

Cheers,
Roger
