Subject: Software will not communicate with the lock or the AL-DTM Data Transfer Module .

Models: Any software-programmable locks

If the DL-Windows software will not communicate with your lock or your AL-DTM Data Transfer Module, this may be due to:

An issue with a COM port

For systems that have been working correctly for an extended time, a solution may be a simple COM port test and/or a reset of the active COM port. For new installations of the DL-Windows software, the solution may require installing (or re-installing) the necessary USB drivers.
