Conference 49.910::kav30

	In general: we are using certified components to meet the specs...

	For the details in your question I have to go back to the design
	engineers, this  will take time...

	Another possibility may be to talk to the safety engineer in Reading
	(UK), who did the certification for us. His name is Eric Monk,
	RDGENG::MONK, DTN 830-6374.

... however, if you stumble across the information, could you post it here?

Thanks!

Hi Thomas,

I haven't heard back from Eric yet - perhaps is is on holiday.

Thanks to some KAV30 spec information I got from Aldo Castellucci, I did find
that the following standards apply:

   The Thick Wire Ethernet interface  will  comply  to  the  Digital Ethernet
   Standard DECstd 134.

|  The SCSI interface will be electrically  and  logically  compliant  to the
|  SCSI-2 standard and the DEC implementation of the SCSI-2 Standard.

   The product shall meet DECstd 119 and  comply  to  the  'Reference Module'
   safetywise.

However, this doesn't give specific methodology used to limit the current
as requested by the customer.

Thanks again for any info you can dig up for this customer (LVT Kodak) on
this issue.

Regards,

Alan

    I just spoke with the customer on Friday. What he is exactly trying to 
    accomplish is to get a color photo replication printer approved by the 
    above mentioned UL standards/safety body. The printer has an embeded
    KAV30, and in our documentation we state the KAV30 has already been
    stamped by this safety body. Whatt the customer needs to know, is how did
    we pass the safety test ? Most of the test hinges on the power coming
    out of the various outputs off of the KAV30, i.e the scsi, aui, console
    and aux ports. The customer feels he can measure the power to each pin
    of the four outputs, but some of these test could be destructive, and
    would be a waste of time since digital obviously measured this already
    (when we passed the safety test). Did we "fuse" the lines or what ?. 
    
    
    Thanks for your help, I really need to respond to the customer ASAP,

	I don't think we ever stated that the KAV30 is UL "stamped", but it
	is SELV compliant. The certification was done by the (internal)
	'European Product Safety Laboratory' in Reading, UK (Eric Monk).
	The 'Certificate of Design Compliance' we've got from this group
	states:
	
	'The equipment ... meets the design requirements of the following
	safety standards:

	DEC Std. 119 rev K
	EN60950 (european equivalent of UL1950) '

	As far as I remember this evaluation/certification was based on
	Schematics, parts list, layout drawings and manufacturing plans.
	There was no active testing involved (but I may be wrong here,
	I'll try to contact Eric Monk again). If this would help, I could
	fax you a copy of the certification.

Hi Thomas,

I spoke with Stan again today.

I'm not sure the testing method is what Stan and his customer require.  Rather 
it is how do we assure that the serial, AUI, and SCSI ports will put out only 
X Volts?  What is the physical/electronic method of controlling this?
For this information, I believe you are correct that one would need to go
back to the schematics, parts list, and layouts to find what is on the other
end of the pins on those ports to limit the voltage.

Thanks again for any information you can provide on this.  Looks like the 
customer is up against some delivery deadline and needs to clear this 
certification hurdle.

	I have an engineer now looking at the schematics, expect to have
	the info within the next several days...
