[Elecraft] K3 to Expert Amp cable ?

[Ed Stallman]

Hello Group

My 2k-fa will be here in a week of so , in preparation I bought 2 ea DB9 
Female and 2 ea DB15 male connectors (SO2R)

Here's my setup : K3 connected to computer using LP-Pan and LP-Bridge to 
connect to N1MM and NAP3 ... Looking in LP-Bridge , I have a Output Com 
Port #1 and #2 and on my computer I have unused DB9 ports .

My question's : Did I buy the correct DB15 connector ? Can someone 
please tell me the connection from the DB9 to the DB15 ? I will not be 
using ALC  or the option to turn on the 2K-FA with the K3 , simply need 
the CAT.

#2 K3 and computer will be setup  the same.

Thanks for your help
