You should be able to simply replace the CI-V output of the 
ProIII with the CI-V output of the microKEYER II.  Connect 
the PW-1 and SteppIR in parallel and both will follow along 
with the simulated transceive data on the MK II CI-V output. 
Configure Router for "TX Frequency,"  9600 bps and 6E ... 
the PW-1 and SteppIR should operate just as they did with 
the Pro III. 

There are two possible "improvements" .... 

1) you can move the SteppIR to the MK II iLINK port and control 
   it using the SteppIR protocol (available for any rig) which 
   will inhibit PTT while the SteppIR is tuning, add hysteresis 
   at the 25/50 KHz points and track the transmitter frequency 
   (vs. VFO A with the K3).  

2) You may want to consider connecting the K3 +12V output to 
   pin 7 and ground to pin 2 of the PW-1 ACC connector.  This 
   should allow use of the PW-1 antenna switch with the PW-1 
   turned off (page 9 of the manual).
