Apex Jr. AquaBus Modules

Apetty32 · 01/05/2012, 10:39 PM

I am currently running my system with an apex jr. I added on an Eb8 which used one of the two available aquaBus ports. System at this point is working great. I decided to get a PM1 to add a Breakout box and ph probe. Now I am stuck with no more aquaBus connections on the unit. I wanted to add a lunar simulator to the system and from doing my readin online it says the system supports 4 or 5 aquaBus accessories. How would I connect these to the unit and why can I only add 2 more now when there will always be ports available on a unit.
All in all:

1. What Aquabus ports do I use if my apex jr has 2 ports and both are being used (EB8 and PM1). Should I use the aquaBus on the EB8?

2. Why can I only add 4or 5 aquaBus accessories what is stopping the expansion of more EB8's or lunar simulators? If there is something stopping more than 5 is there a way around that?

Each EB8 has 4 AquaBus connectors; the bus is common and you can connect any device at any bus port. I need to check on the limits to be sure what they are.

There is a hard limit built into the Apex Jr. You can add 4 of any type of AquaBus expansion module (EB4, EB8, PM1/2/3, LSM, WXM, VDM) plus a display module for the total limit of 5.

Need more than that? Upgrading to a full Apex or Apex Lite is the only way around the Jr's limit.

Bump this up. I just ran into this issue. What a joke! I have $700 in Neptune stuff and I can't use another module. No other Apex will fit where my JR is and I am attempting to control another tank as well with the JR. There is absolutely no reason for this limit.
