The RS-232 connector on the K3 will be the opposite sex of Kenwood & Yaesu,
which use a male DB9 connector on the radio.
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.
