Command Board Jumpers

Post by RAF »

I'm attempting an integration to a T99DX-132W dashmount Astro Spectra which has never been setup to route even basic functions like PTT to the DB15F auxiliary connector. I've ordered the detail manual but an unexpected business trip makes it essential I get this done now. A search of the archives shows this has been discussed and previously and one of the group members indicated he had photos identifying the jumpers and their locations. I e-mailed him through the forum but have received no response thus far and I also noted that a number of you had requested copies of those photos so I'm now broadcasting a request for assistance ot anyone that can help me out for fear I will not receive the detailed manual in time to get this done and tested before I must depart.
Thanks in advance for any assistanceyou may be able to render!

To get the 15 pin connector to have a mic hi input (on pin 15), move JU521 to JU513. To get PTT (on pin 13), move JU518 to JU500.

I don't have photos at this time, but I'll see if I can get some today.
