What model of TracVision are you working with? I have worked with a LM and got it all hooked up after buying old receivers off of E-bay that have the serial port to make the in motion work, only to find out that in one month Dish discontinued support of the receivers that I needed to work with the LM. I can no longer use the LM with any receiver so all of my time was wasted for 1 month of use.
