It isn't shown on the schematic, but elsewhere in the rotator docs (page 5, External Control) it
specifies 0-4.5V DC for the position sensing outputs. Depending on the existing interface, a simple
voltage divider would probably do. I don't have an LVB tracker, so I can't comment on that end.

<The Great South Bay, Amateur Radio Club, of which I?m a member wants to put together a satellite
<They have an existing home made AZ EL power unit which works. They are looking into interfacing an
<LVB tracker with it.
<and need to know what voltage level input is required for the feedback loop. The unit currently puts
<out 0-6.25vdc corresponding to 0-360 AZ and 0-180 EL. Looking at the G5500 schematic they go
<through an opamp arrangement but do not provide any voltage levels.
<If anyone can the club with some info I'd sure appreciate it.
