General Description

The Model HSC-1 Stepper Motor Controlled Huber Slit Driver is a compact, light weight unit that contains 2 stepper motors and their microprocessor controlled driver. The units are designed to be daisy chained so that a single RS-232 line can control multiple slits. Power is provided to the units through the same daisy chain, allowing multiple units to be powered from a single HSC-PWR Power Converter. Daisy chaining is via DB-9 connectors, allowing the user to simply make up ribbon cable connectors for this purpose. The onboard microcontroller accepts simple ASCII commands to move the slits. Step size is 2.5 microns at 200 steps/revolution. Individual slit motions and the pseudo-motor motions "open/close" and "slide" are supported. Motor power turned off after each move to save power and reduce switching noise in the vicinity. Current locations are saved to non-volatile memory on power failure
The Model HSC-PWR Power Converter is a wall trans-former unit which generates power for up to 4 HSC-1's. The unit comprises two parts, the transformer itself and an adapter cable which places both power and RS-232 signals onto 9 lines for daisy chaining between successive HSC-1's.

Applications

The HSC-1 provides precise remote control so that slits can be adjusted while the x-ray beam is on. Its low cost allows this control to be implemented on all Huber slits, whether they need to be adjusted only occasionally or as part of the experimental data collection process. The HSC-1's compact size and light weight makes it an ideal candidate for controlling slits on diffractometer arms as well as on stationary beam paths. Retrofitting existing slits is easy too and does not require machining the knurled knobs.
