This software is designed to work with version 7.0 of the SDU5000 EEPROM. This version of the SDU's internal software supports the high speed "K" command and the AR5000. If your SDU5000 has a serial number below 005901 and you have not already upgraded, you will need to do so. A version 7.0 (or above) EEPROM can be obtained from your AOR dealer.
