Aquapure Ei won't connect to iAqualink

I have checked the wiring and installation, all is good there. Can't get the Aquapure ei to connect to the iaqualink. Any suggestions?

I'm sorry that I can't help with this problem but did want to pop in and say hi and welcome you to the Pool Forum! Hopefully, someone will come along who can offer you some advice.

I Googled, but didn't find anything here or on other sites. The only suggestion I can offer is to call Zodiac:
