[WriteLog] Multi-keyer and ICE 419

[EA5BY]

Hi all,
 
Please I need some help on this matter:
 
I have a SO2R setup and I wonder if I could connect my Multi-keyer
(W5XD/K5DJ) to the two ICE 419 I have, and make them change bands in auto
mode.
 
Maybe using the ANT-RLY ports in the multi-keyer?
If so, please what are the connections between devices?
 
Thanks so much in advance.
Season's greetings and HNY.
