  • Page 6: Programming Overview

    The Spectrum Master is a DTE-type serial device. Communication between the Spectrum Master and a PC is accomplished over a null modem serial cable provided with the Spectrum Master (Anritsu part number 800-441). Connect the cable to the Serial Interface connector on the Spectrum Master test connector panel and to the appropriate COM port connector on the Serial Communication Parameters The Spectrum Master begins communication at 9600 bps when first powered on.
  • Page 7 current sweep may be incomplete. Once a response string is received from the Spectrum Master, the unit is ready to accept additional control bytes. Exiting Remote Mode To exit remote mode, send the Exit Remote Control byte #255 (FFh) to the Spectrum Master. The Spectrum Master sends a response byte of 255 (FFh) then exits remote mode.

  • Page 12: Control Byte Descriptions

    Control Byte Descriptions Setup System – Control Byte #1 (01h) Description: Sets system status flags and switches. The current value of the flags can be obtained by executing command #29, Query System Setup, and parsing the values from the appropriate bytes. The Spectrum Master acts on the entire byte, so the state of each of the bits must be defined every time the command is issued.
