"A male connector on the device implies wiring as Data Terminal Equipment (DTE) such as the serial port on a PC. A female connector on the device implies wiring as Data Communications Equipment (DCE) such as a telephone modem (remember those? :-) In general, if the sex of the connectors of the two devices you are interconnecting is the same, a "null modem" cable (swaps various pin pairs) is implied. If the sex is opposite, a straight-through cable is implied. The K3 uses a standard, straight-through, male-to-female cable. Its DE-9 connector is wired as DCE. 73, Lyle KK7P"
"The RS232 connector on the K3 rear panel has nine pins inside its shell. The mating connector that plugs into it has nine corresponding sockets inside its shell. Depending on whether you base the connector gender on the pins/sockets or the shell geometry that contains them, you might call the same connector either "male" or "female". That's why some engineers prefer to use pins and sockets terminology rather than gender. In any case, the RS232 DE-9P connector on the K3 has nine pins inside its shell, which is the same as other radios. The Accessory DE-15S connector on the K3 has fifteen sockets inside its shell. 73,Ed - W0YK" I think these two statements say the opposite - so I'm still confused. Per Ed, the connector on the K3 is a DE-9P (same as Kenwood & Yaesu). I think that Lyle is saying it is a DE-9S.
