Not sure if anyone else knows about this. I installed my ZT-2 WB this past weekend and found that the controller and display are a previous gen. The Zeitronix website shows how to get display of the TPS and USer inputs out on the AFRM display but you need the latest gen to do that. I sent them an email asking about an upgrade path and this was their response which seems pretty reasonable. I thought I'd post it here in case anyone else has same dilemma. I'm also experiencing problem with the AFRM and PC linking up to the controller when using the splitter.

Dominic,
sorry for the delay. We are at the Sema show in Vegas which limits our time to process the e-mails.
To update your Zt-2 to the new specs you would need to send us the Zt-2 and the LCD display + issue a payment of $10 for S&H. Please send the splitter and the logging cable for testing along with the unit.

Please attach this e-mail and your return address.
