I have a Yaesu MD-100A8X microphone and was interested in connecting it to my FLEX-1500.

The mic has a RJ-45 port and an 8-pin Foster jack on the base of the mic. For my [old] configuration, I had a conversion cable that connected the RJ-45 port on the mic to the 8 pin connector on my FT-1000. W0VB and I traced and mapped out this RJ-45 to 8 pin (Yaesu) conversion cable and applied to to the Flex RJ-45 pinouts:

Purpose  8-PIN Foster (Yaesu)
RJ-45 (Yaesu)  RJ-45 (FLEX) 
 UP  1  1  1
 Down  2  2  2
 +5V  2  3  3
 MIC (-)  7  4  4
 MIC (+)  8  5  5
 PTT  6  6  6
 Ground  5  7  7
 Fast  4  8  8


As expected, the RJ-45 connections are identical.  I built a straight through Cat5 cable (I'm a bit rusty - it only took 3 tries. ... but it was worth the laughs with Terry.)  After final verification that cabling was correct, I plugged the mic into the FLEX-1500.  I didn't spend much time on the up/down switch, but PTT and the mic are working.  The audio sounds really good.
