[Elecraft] K3 RRC-1258MkII question

[cx7tt at 4email.net]

Hello All

Recently got the remote control box RRC-1258MkII for my K3/100. The
instructions say nothing about opening the box and using the jumpers
that came in the control box package, although the RRC web site
shows such being done. Has the Elecraft box already been configured
for the K3?

For the power for the 1258, may I use the 12v from the aux power port on
the back of the K3? It has had the mod to bring it up to 1A. My K3/100
is Serial 250.
