I use the Microham   Micro Keyer II to do this.

Your question has two answers:

 For the 2KL a BCD to 1 of 8 decoder can switch the necessary
 voltage dividers to create the analog (stepped voltage) band
 data signal needed to switch bands with the 2KL or 4KL.  The
 W9XT "BCD-10" is capable of providing the necessary "switch
 to ground" signals to easily drive a set of voltage dividers
 in this application.

 However, unlike most of the other Icom accessories, the PW-1
 will not switch bands based on the analog (stepped voltage)
 signal and requires specific frequency data from the Icom
 CI-V "transceive" broadcast. .  

 I know of only three devices in current production that will
 translate Elecraft (Kenwood) CAT data to the Icom CI-V format.
 They are: microHAM Station Master (PA control function),  the  
 microHAM microKEYER II (auxiliary CI-V output) and microHAM
 MK2R or MK2R+ (accessory serial function).  The now discontinued
 microHAM Band Decoder is also capable of providing the CAT
 translation if you can find a used one.
