Hi, Guy`s,
I`m looking to build a joystick controlled CCTV pan & tilt unit without the need of a computer. With that in mind I bought some parts, all in one bundle, and mainly for the stepper motors, on ebay and wonder if it is possible to achieve my goal using only these (which I doubt), or would I need additional parts?
The ebay items, which were knocked-up by B.I.C. Electronics, England, were part of a film viewing/editing setup and is not complete.
There are 3 stepper motors, all the same, as in the photo - Two have a 15-pin connector and the other, 25-pin. There are also 4 Airpax 12 vdc motors which were made in Holland.
The lens I am using weighs just over a kilo, so with camera attached, it should work out less than 2.5k and these motors appear adequate.
There is probably a lot easier way and I would appreciate any help, or advise, you can give me.
Cheers

Unit1 - Front panel:
Has `FILM SPOOLS` printed on it and under that, two switches, one marked `TOP LOAD` - `BOTTOM LOAD`, the other `OFF - ON`, there is also an ON/OFF mains switch.
Rear panel has two leads marked `PRINTER` and `VIEWER`, also two 15-pin connectors marked `WINDER` and `CONTROLLER`. When I connect the joystick to `CONTROLLER` and one of the stepper motors to `WINDER` it goes through all the motions ie. fast, slow, forward, reverse, and speeds in-between depending on position of joystick. When pressed, two buttons on joystick unit (PAGE BACK/PAGE FWD) run the motor for a short/fixed time.
Inside are two boards, one on top of the other:
Top board has 4 relays and is marked: 930601-01-4 MOD1 and 930601-14-4 ISS 1 Side2
Bottom board is marked: RS 332 - 098 4-Phase unipolar stepper motor drive board
---------------------------------------------------------------------------------------
Unit2 - Front panel:
(See photo) Two switches marked TOP LOAD/BOTTOM LOAD and SPOOLS OFF/SPOOLS ON. I haven`t any leads to test this unit but when switched on the `WATCHDOG` LED if flickering as though in readiness.
Inside there is the main board marked B.I.C. 970400 - 14 - 4 ISS-3 SERIAL NO. 97 ... (custom made?). There is also a seperate board marked `RS 240 - 7920` (4-Phase unipolar stepper motor drive board ?).
The rear panel has on/off switch, 15-pin, 25-pin, 9-pin female connectors and 2 DIN connectors , 5 and 7 pin.

Stepper motors - 8 wires:
25-pin and 15-pin stepper motor connector has 10 wires attached, although 2 black wires have been cut toward the motor end.
