[Elecraft] K3 & Piglet

[H. Cary]

Santa brought me an iPadAir for Xmas and I'd like to sync it w/ a Piglet (Pignology product) for CW and digital modes as shown in Sept. 2013 CQ article and to use w/ HamLog. 
The Piglet has an RS-232 male connector and my IPad has a lightening connector at the iPad w/ a USB connector at the other end. Surely there must be an adapter plug to connect these two varieties (USB/RS-232) but my on-line search hasn't found one.

Has anyone on the reflector successfully put together a similar setup and could point me in the right direction?

73 & Happy New Year,
Cary, K4TM
