MST 488-27 Controller
Kepco's 'Digital Highway' illustrates the interconnection of Kepco Products, including the MST 488-27 Controller.
The MST 488-27 communicates with its Host computer over the IEEE 488 bus (GPIB) using either CIIL (Control Interface Intermediate Language) or SCPI (Standard Commands for Programmable Instruments) Languages. An auxiliary input port allows for communication via the RS 232-C (EIA 232) standard serial communications bus.
EPICS Driver (Linux compatible) now available!
The IEEE 488 GPIB interface functions implemented by the controller are defined by the IEEE 488 Standard.
The MST 488-27 Controller interfaces to an MST power module via the RA 55 Rack Adapter; interconnection to the Host Computer on the GPIB is made via an IEEE 488 standard cable. If the serial port is used for communications between the controller and a computer terminal, a 9 pin null-modem RS 232-C connector/cable is required.
The MST 488-27 Controller is comprised of a single-board computer (SBC) and power supply housed in a 1/9 Rack (7" high by 1-3/4" wide by 20-1/4" deep) case.
The Host Computer can set the output voltage with current limit, or the output current with voltage limit. The Host Computer can then have the MST 488-27 read back the actual output voltage and current delivered by each of the power modules to their respective loads. The MST 488-27 is continually polling all of the power modules on the IEEE 1118 bus for error flags.
All data transmissions over the GPIB are ASCII encoded. The values for the command parameters can be written in integer, decimal or scientific notation.
