[Hai-users] 17a00 problem

[Tom Williamson]

I have a system that uses a 17a00 expansion enclosure.  Last night all the zones on it went into trouble indication.  

The status light on the 17a00 is blinking slow (normally this is good), I can send a command to turn on the outputs on the board, and all the consoles in this area function fine (so the a/b data line seems to be ok).  But PCACCESS shows comm status as BAD and none of the zones register correctly. 

Any ideas on what to look for?

Thanks
Tom
