[Elecraft] Remoterig k3/0 mini won't power up remote K3

[kb2m at arrl.net]

 I'm in the middle of setting up my K3 K3/0 mini Remoterig 1258 pair setup.
It's going well, I have most everything done at the remote site. I have
DXLab running on a laptop controlling the remote K3 via the control K3/0
mini. All I have left to do at the remote site is the cable mod for the
KPA500. 
 I have one issue. The control station powers down the K3 and KAT500, but
not the KPA500. This should work when I do the KPA500 cable mod. The issue
is that when I turn on the K3/0 mini it doesn't turn on the remote K3. I see
a config item for a Yaesu radio in the Microbit s/w, but not sure it's for
an Elecraft setup. Anyone have an answer to this problem? Any suggestions ?
Before I try remoting from another site I would like to be able to power the
remote equipment on and off...
