My DL-Windows software will not communicate with my lock nor with my AL-DTM Data Transfer Module. What can I do?

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

• A faulty cable that connects between your PC and your lock / AL-DTM
• 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.

Perform a COM Port Test: DL-Windows V4.1.96

1. Click Tools > COM Port Setup and Test.

2. Set the radio button to "Test All" (default selection) and click Test.

3. In the Loopback Test results screen, one of the four COM ports should appear with the message "Loopback Passed, Comport set to COM: #" (example shown below). Click to select the COM port radio button that passed the test, then click Set.

Perform a COM Port Test: DL-Windows V5.x.x

1. Click Tools > COM Port Setup and Test.

2. Set the radio button to "Test All" (default selection) and click Test.

3. In the Loopback Test results screen, one of the four COM ports should appear with the message "Loopback test passed. COM Port set to COM#" (example shown below). Click to select the COM port radio button that passed the test, then click Set.

If the COM port is not detected, open the Control Panel > Device Manager to determine if the cable is being detected and if the correct USB drivers are installed.
