    Keysight 66000© Mainframe. Model 27553 is comprised an RA 55H Rack adapter which has nine slots and the MST 488-27HT Controller which is installed in one of the RA 55H slots. The MST 488-27HT Controller is designed to program, control and monitor Kepco MST-MHT Series power modules installed in the remaining slots of the RA 55H which are functional replacements for Keysight 61000©...

    The Host Computer can set the output voltage with current limit, or the output current with volt- age limit. The Host Computer can then have the MST 488-27HT read back the actual output voltage and current delivered by each of the MST power modules to their respective loads. The MST 488-27HT is continually polling all of the power modules on the Control Bus for overvolt- age, overcurrent, and other errors.

    2.2.4 INSERTION To insert the MST 488-27HT Controller in the RA 55 Rack Adapter, proceed as follows: 1. To ensure full engagement of the module interconnect to the RA 55 Rack Adapter, pull out the two slotted captive thumb screws (at the front of the Controller) and turn counterclock- wise until the threads engage.

  • Page 18: Final System Interconnections

    FINAL SYSTEM INTERCONNECTIONS 1. Install the MST 488-27HT in the left-most slot of the RA 55 Rack Adapter (see PAR. 2.2.4). If the rack adapter has a plate used for mounting a power module connector in slot 9, the plate must first be removed to accommodate the MST 488-27HT controller by removing four screws securing the plate to the rack adapter chassis.
  • Page 19 AC INPUT. The MST 488-27HT draws power from the same source used to power the MST power modules. Power is applied through the Rack Adapter via the AC/control bus connec- tor. b. IEEE 488 BUS. This port is a 24 pin IEEE 488 connector and conforms mechanically and electrically to the IEEE 488 standard.

  • Page 23: Section 3 - Operation

    Controller No Capability Tables 3-2 and 3-3 define the messages sent to the MST 488-27HT, or received by the MST 488-27HT, via the IEEE 488 bus in IEEE 488 command mode and IEEE 488 data mode, respec- tively. These messages are enabled during the “handshake” cycle, with the MST 488-27HT con- troller operating as either a Talker or a Listener.

  • Page 24: String Parsing

    3.2.1 STRING PARSING When the MST 488-27HT is in listen mode, strings are accepted. When the host controller sends the last byte it can assert the EOI line to indicate the string is complete. The GPIB listener function automatically adds a LF to terminate the string input. The parsing software then pro- cesses the string and if there are valid commands, the power supply is updated with the new control input.

    The string contains the manufacturer name, model, SN, firmware revs. The SN field is normally used for the serial #, but since the MST 488-27HT has no NVRAM, serial #s are not stored in memory; the power module current rating is given instead. The firmware revision con- sists of the controller rev.

    LONG Form: SYSTem:SET {SA0 | SA1 | CM0 | CM1 | SI0 |} Description: Allows the unit to behave as a standard Kepco MST 488-27 Controller (programmer). Sending SYST:SET SA0 disables the default secondary address mode of the MST 488HT controller and causes the unit to revert to the command syntax of the non-HT suffix MST 488-27 Controller (Pro- grammer).
