controlling old molynx P&T or videmech P&T

[superdupercooper 0]

hi

 

i have got a couple of old P&Ts and would like to get either of them working, probably so i can put a telescope and camera on to do some star gazing from the nice warm inside

 

i have 2x Molynx PT7T-240 and 1x Videmech 650.

 

i know both units are 240V, but not much more.

 

it would be great if someone could supply the specs of these units, maybe advise on how to control them from a PC.

 

i'm an electronic engineer familiar with RS-485, RS-232 and I could make some control circuits if necessary, but don't like tinkering with 240V so if there is a standalone interface controller that would be best.

 

thanks

those sound like the big pan tilts you see on the side of banks etc.

 

They are directly controlled with mains voltage, they dont usually have any inbuilt circuitry for low voltage control with rs232 etc.

 

You can get control units for them, google for building block video (BBV) they do a full range of telelmetry decoders that can control these units.

 

You can sometimes pick them up on ebay cheap once you have found the type you require.
