Solder the wires to the male DB-9 connector supplied with your
transverter as shown in Figure 48.

Follow the color codes shown below when wiring the
connector. The same color code is used in the control interface cables
for other Elecraft equipment. Keeping a consistent color code will
help avoid assembly mistakes and make troubleshooting easier.

Figure 48. K2 Control Cable Wiring.
If you have not built an RS-232 or control cable to connect other
equipment to your K2, you should have an unused DB-9 male connector
that was supplied with the KI02 or KPA100 kit. In that case, wire the
connector as shown in Figure 48. If you have wired the cable for the K2
and other accessories already, add the transverter extension(s) to it as
shown on the next page (Figure 50).
Attach the connector housing to the transverter connector(s) as shown
in Figure 49. The cable clamp has enough capacity to handle up to three
cables. Before closing the housing, be sure that:
The clamp holds the cables securely, so that strain cannot be
placed on the soldered joints.
The jack screws are positioned between the stops so the threaded
ends cannot extend more than about 1/8” (3 mm) beyond the
housing. If they extend too far they will prevent the connectors
from mating fully, resulting in intermittent or open connections.
