CX700: SPS not recognized and marked faulted - SPS' green led constantly on
Hi there,
a few weeks ago we got two used CX700 arrays for a laugh of a price.
Everything seems fine except this issue:
One SPE does not really recognize its pair of SPS.
I cabled it all correctly, the SPS are showing the green LED lit constantly.
I attached the RS232-wires which came with the system. SP-A reports the SPS as faulted and an "Invalid serial cable", SP-B flags its SPS as not present with "cabling status is unknown".
I tried several cables, built some on my own.
All pins are wired correctly, ground connection is present.
Any Ideas on this?
Thanks!
-Chris

The issue can be considered closed.
After endless reboots of both SP and SPS, as well as cleaning all pins and sleeves with a fiber brush, both SPS are now recognized and functioning normally.
Sigh.

I investigated a bit more:
The SPs do poll the SPS with the COND? statement - so the SP's RS interface seems to be working (read at 9600, 8N1).
The SPS does not answer at all - even when attaching the device directly to my computer with a nullmodem cable (also tried straight, no difference) there'r nothing to see.
I guess I should read anything when I remove the power from the SPS?
I think I've seen a Max232 in the SPS - how likely do you consider it to be blown (what a coincidence that two of these are blown in two devices at a time...)
The PIC seems to be working since the LEDs work properly...
Cheers
