[Elecraft] "Y" Cable when using the KPA100 and KAT100 in the EC-2

[Todd J Gahagan]

I need to extend the length of the Y cable coming off of the back of the K2 that goes to my computer.  Can I just use a plain DB-9 to DB-9 extension cable?  Probably a dumb question but I don't want to fry anything in the KIO2.

Thanks,
