Pittsville, heres some threads with posts that may be of help making and connecting a serial cable.

shows the orientation of the microHD connector and also guides you through the process.
If your Ali editor program was downloaded from here some time ago, re-download the editor as I found the editor to be corrupted some time ago and Brian re-posted it. The edit would run, the info screen listed the same version but when the old and new ones were compared with a hex editor there were a few different bytes causing some channel list editing to corrupt the channel list. Please see the following thread:

If your TTL/RS232 converters do not need to get their power from the microHD, then you only need to connect the Transmit data, Receive data and ground. Remember to cross your transmit and receive data wires. i.e. Transmitted data from the PC goes to the Receive data on the microHD, and Transmitted data from the microHD goes to the Receive data on the PC.
Heres the thread for cable I made:
http://www.satelliteguys.us/threads/305802-Serial-Transfer-Cable-for-the-microHD
and as stated in that thread I did not connect the 5 volts to the microHD, but used a 9 volt battery and a 7805 voltage regulator to power the converter chip as I only had 3 pins in my connector. (one space had no pin in the connector I used)
