The requirement as posted in another reply has a SUCH AS, in the requirement which means the requirement is two types of peripheral attachments but the such as are just examples. Not hard requirements as read and interpreted by some. Brodie Pedersen

They’re ahead of us on this question. When it comes out in a few weeks, get a copy of the new 2003 version of ANSI C63.4. It expresses a preference for the traditional serial and parallel ports, but has you go on to USB, Firewire, etc if the traditional ports aren’t present.

Note that ANSI C63.4 does not say “RS-232 serial interface”, just “serial interface”. I think that will take care of the problem for the desktop machine for now. Now, what if you use a host that doesn’t have a parallel port? I would use my “engineering judgment” that says it’s real hard to test a port that doesn’t exist. In the meantime, this is a good point to bring up to ANSI C63 for the next update to C63.4. Ghery S. Pettit Intel Corporation From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Sunday, January 18, 2004 11:14 PM To: [email protected] Subject: ANSI Minimum Configuration Requirement Hello, I recently ran into a question on the "minimum configuration" for emissions testing on a computer peripheral as stated in ANSI C63.4 and EN 55022. The standards say you must have a serial and parallel device connected to the computer, as a minimum configuration, when testing a computer peripheral. Recently, I purchased a new Dell laptop, which does not have parallel or serial ports. It only has 2 USB and a video port. I also have a new Dell desktop, which has a parallel port, and a bunch of USB ports, but no serial port. Is there an exception for these computers, which are phasing out the old serial and parallel ports? How do I meet the "minimum configuration" requirement? Thanks in advance, Tim Pierce
