Mike,
DE-9 is the proper designation for what most call the DB-9 connector.
The proper "DB" designation is for the wide 25 pin size housing that was
used for printers on the PC and on commercial modems.
When the IBM PC first came out, they used 9 pin connectors for the
serial ports and many referred to them as DB-9 even though the proper
designation for that size connector (no matter how many pins) is "DE".

I just acquired a P3, but was surprised to learn that I need a cable (CBLP3Y)
to enable the K3 VFO frequency to be displayed on the P3. I located in my
toy box a couple cables of same description as the CBLP3Y, that being they
are terminated on one end by a RJ45 connector and a DB9 Male on the other.
(I see in page 4 of the P3 owner's manual it calls this cable a Male-Female
DE-9, so that is confusing to me. What is a DE-9 connector?). My question
is to ask if my toy box cables will do the job, or is there something
specific to the CBLP3Y that designates that as the only cable to use?
