We currently have a sick, older IQ system using Turbo1.4, DRN-16, MRX, SMX, White EQ, PIP-DP / DSP. System has been performing well until last Sunday, when we noticed an amp / PIP had dropped offline. Data frame was reloaded and all seemed normal.
Returning 48 hrs. later ALL PIP's had dropped offline. This is where it gets worse...many attempts loading data files, with various results; miscounts of devices, not seeing devices or even when a roll call was completed successfully no audio would pass, amp ch. muted (manual toggling had no effect). No loop breaks (there are 2) have been detected, and as far as can be determined by us the hardware devices seem to be OK.
We believe that this may be a host computer problem, we have run MS scandisk with no untoward results. (It did however run for about 30 min before PIPs started dropping offline, all in about 10 min.) The RS232 serial port seems to be communicating with the drone ok (roll calls). No outwardly apparent computer issues seem to be present though.
Any one having any similar experience or detailed knowledge of these "older antique" systems please reply. Regards,
