I have a homemade JTAG I would like to try on a 301-103 Single TSOP IRD.
This has 20 pads where the JTAG connects I have the wires from my JTAG labeled TMS, TCK, TDI, TDO, TRST, VCC, GND. I have not been able to find a picture or a document that gives you the IRD board location for TMS, TCK, TDI, TDO, TRST. I already connected Ground and VCC with no problem. Could someone let me know these pad locations.
Thanks,

Look at the pads closeup(from underneath). the row of pads with no leads coming from them are ground. Now looking at the pads with the ground row of pads away from you, the 1st pad starting from the right is pad number one/TMS, then TCK, TD1, TD0, TRST.
