Simple scanning! The 789A-4 drive controller includes auto-direction setup. Just connect it to a suitably equipped monochromator; There are fault indicator lights if there is a problem with drive circuitry. A complete list of ASCII commands appear on the reverse side of this data sheet. Example programs are available upon request. National Instruments LabView™ software drivers are available for download.
When ordered with a system, the Model 789A-4 comes complete with stepper motor to fit McPherson monochromators or sampling accessories. The cables for limit switches, motor, RS232 communications (with a USB adapter), and power input are included.
If ordered as a retrofit for an existing monochromator an internal switch for motor direction is provided. Indicate the model and serial number of the instrument.
