[amsat-bb] Yaesu G-5500 and Labjack Piggyback

[Bob Hammond]

I'm building a "piggyback" to go with my Labjack U3 and have a question
about the output of the G-5500 DIN connector.

As I understand the G-5500 manual, connecting certain pins to ground makes
the rotator move in certain directions.  What I measure is about 15Vdc on
all of the "direction" pins relative to pin 8 which is ground.

Do I have something wrong with my G-5500 controller box?  (not my piggback
board).

thanks,

Bob
