CAUTION: Earlier lines of controllers sometimes required the “wrap plug” to force the controller into maintenance
mode. DO NOT use the wrap plug on the PXNplus CPU board. To properly set the controller into
maintenance mode, short JP3 (Shutdown Request) for about 5 seconds until DS8 turns on. DS2 and
DS3 will then alternate ON and OFF.
