BendixKing released a software upgrade, (SW) 01/06, in June 2018 for ART-2100 radar transceiver, part numbers 071-01550-0101 and -0201, to address memory corruption issues during power-on or shutdown procedures. The ART-2100 units must already have Mod 9 installed in order to perform this software upgrade.
When power is removed from the unit during the BITE (built-in test equipment) test, the nonvolatile memory can become corrupted. This means if the system is turned to the "off" position just after power-on or during system shut-down, before the self-calibration is completed, the unit's memory can become corrupted.
A previous Service Aid, SA ART-2100-107, instructed operators to turn system to "standby" for five seconds, allowing this self-calibration to be completed before turning the system to the "off" position. This is still good practice even with the software upgrade.
This software upgrade will:
After software installation, the unit requires several hours of calibration through several temperature ranges from +70C to -55C.
