About MDT Server

MDT Server is a server application that facilitates sending and receiving of manifest events, configuration, and text message data between Trapeze and the mobile computer vendor gateway.

The MDT Server application should be set up in your file server in the Trapeze4 directory or a BINMDT directory as advised by your Trapeze representative.

After starting the program, you must configure the interface with the specific information required by your mobile computer vendor. Please contact your Trapeze representative for more information.
