[edit] Not a protocol

I think EIA 422 is more of a "signalling standard" than a "protocol" - it doesn't specify much related to communications, more just voltage levels and slew rates. There is a terrible tendancy to broaden the use of terms into uselessness - a wheel isn't just round, it's "an implementation of circular technology". --Wtshymanski 18:55, 3 June 2006 (UTC)

[edit] Pin assignment

I have come to believe that connector pin assignments, specifically for DB9 connectors, were not standardized in the RS422 specification. Is this true? If it is true, the article should include a short statement about this, and the rationale. Now it appears that if I get a USB-RS422 adapter, I have to worry about each manufacturer's choice for the pin assignment. —The preceding unsigned comment was added by 157.127.124.15 (talk) 19:23, 5 February 2007 (UTC).
