DIY Minitor V Programming Cable
Thanks to this thread i was able to build a functional Motorola Minitor V Programming "Kit", using the Radio Shack "USB Scanner Programming Cable". I ran into some problems early on with trying to use a TRS Jack which was the first mentioned method. I went to the local Radio Shack and picked up one of the DIY project enclosures along with the TRS jack. I wired together the project, held it to my Minitor V, read the codeplug from the radio... alas nothing happened.
Not being easily defeated i decided to try my own method. I'll explain in detail how I did it but first, see my see screenshots below. I had to use my iPhone for the pictures so the quality is not top notch but you can see what was done.
First separate the top half of the USB scanner housing. To do this i had to use a flat head screwdriver and pry between where the top and the bottom half of the enclosure met.
Next I used a 30watt iron to heat and remove each of three leads on the one end of the board. Note: this is the side with the Black(ground), Red(TX), White(RX). After removing each of the three leads you may need to heat then quickly tap the circuit board on a hard surface to get rid of the excess solder remaining in each of the holes. De-soldering wick would work if you have some laying around. I didn't so I just tapped it on the table a couple times.
The next step is to use wire cutters to remove one end off of three Alligator Clips and strip the jacket off the ends about 1/8th of an inch. I chose Red, Black and Green so I could easily remember which lead was which.
Now I soldered the exposed ends of the alligator clips into the three holes on the circuit board. The order as seen below from RIGHT to LEFT. (TX then RX then Ground.)
At this point I made sure to trim off any excess wire poking through the bottom of the circuit board and made sure my soldering was set and clean. I put the board back into the orange plastic housing and snapped it back together.
Lastly I took three pins from the D-Sub connector (seen below) and clipped them onto the ends of the Alligator Clips.
And done... All of about 25 minutes and you can save yourself $200.00.
Last word:
I am using Windows 7 32bit on my Asus Netbook. I ignored the warning on the USB scanner programming package and had win7 automatically install the drivers for me. Also I have modified the PPS software to allow for engineering mode and changed my single channel voice storage Minitor V into a dual channel voice storage. =)
If you are getting transmission errors when you try to read the codeplug then be sure to follow all of the suggestions mentioned before this post. I had to set my USB delay to 5 seconds before it would work for me. Others have said that 4 works for them. It sounds like it all depends on your setup.
Total cost for me $50.15 versus $250.00 retail cost is outlined below. You might save yourself a little cash if you use the Alligator clip method first. But whatever works, right?
