  • Page 85: Operation

    This Section is reproduced from the ACC-2003 User Guide and provides information on the operation of the ACC-2003 Interface Test Jig. This jig is used for the Service adjustment of the SP200/210 radio. The Calibration program (Calibration.exe) is used to allow the setting of ASIC conditions within the radio.
  • Page 86 Maxon SP200/210 Radio Select the required band and press Enter. Figure 11-2 will be displayed. Figure 11-2 - Calibration Program Primary Screen To dedicate the Communication Port, select Configuration and enter the relevant port number. Selecting EEPROM loading will retrieve the current ASIC values, stored in the radio. This is used for the alignment of the radio.
