I ve got one of them lying about in the shed. Amazing that the whole of the analogue industry was decimated by one simple advance in technology

Needing a positioner for my Aston Simba, and not inclined to shell out for an interface for my actuator, I unearthed my old SR7600 (precursor to the LT, same power supply).
Being cheesed off with the vagaries of my AD3000's relay-driven positioner, I now use the SR7600 for driving the dish, which together with its solid-state motor drive and excellent auto-peaking is far superior to the (at least my) AD3000.
Don't care about having to operate two STB's - as long as it hits the sat dead on every time I don't need to bother with manually fine tune any more.

Thanks Burnham Beech for pointing us to the circuit diagram - it would have been handy to have had that info some time ago when I managed to locate a faulty pair of diodes after much head scratching. That caged power supply tended to overheat over time.

Can I delete the above file now ? - No edit box showing.

You can leave it if you want, it isn't doing any harm.

it was not,what i was saer-ching,i need to nowe what pins
(from the 8)i must used,fore the:max232 interface

In the absence of a schematic you need to trace the pin connections to the receiver RS232 driver. If it's a MAX232 dual driver, check this diagram. Pins 13 and 14 (RX/TX) or 7 and 8 will be the ones going somewhere to your connector pad.
