Driver information is down below. Based on your serial number ending with D or M, that has a 25 pin serial communication connection which might need an older driver. If you have a serial port connection, you'll need driver 2.15j (See information below). If you have a USB/Ethernet connection, you should be good with the latest.

Serial Adapter Driver and Cable
If you are using a USB-Serial adapter the driver will need to be downloaded for that before connecting anything.
USB-to-Serial cutters should use Version 2.15j or 3.02e and can be found here: https://allendatagraph.com/support/software-support
Version 2.15j is not compatible with Windows 11.
