Apex Capacity

[Akersta]

Hello,

What is the maximum capacity of the new Apex in regards to total cable length as well as outlets, modules, etc? I've done some searching but everything I have found so far is for the older systems. Perhaps the new Apex still has the same capabilities but I was hoping it is a little more robust. I have quite a few devices currently with no issues. However, I still have many more to add. Here is what I have currently. Please let me know your thoughts:

• Apex head unit
• (3) EB832 outlets
• (2) EB8 outlets
• (5) PM1 modules
  
• (4) PM2 modules
• (2) WXM modules
• (4) DOS
  
• (1) AFS
  
• Approximately 180' power cable

Looking to add the following items:

• (5) EB832 outlets
• (4) DOS
• (3) Royal Exclusive Red Dragon interface adapters
• (2) ALD
• (2) FMK
• (7) I/O breakout boxes
  
• (150') power cable

Seems like a question would be best answered by Neptune Systems. That is A LOT of equipment. Good luck

You'll be fine adding those. The apex can handle up to 256(I believe) different configurations and modules. And there shouldn't be any limitations as far as cable length

I believe you are correct. Apex likely uses a I2C communication protocol, limiting it to 256 I2C addresses. The only limitation on cable length I am aware of is the use of repeaters in long "USB" cables. This repeater messes up the communication protocol and can cause problems.

Thanks for the feedback. My primary concern is the total cable length and voltage drop but hopefully I'm ok. My longest cable is 50'.

I have several runs over 50', no issues to report.

I believe the guidance is to keep total cable length under 200' but I have seen 50' and 75' cables run without issue for sure.

They use USB protocol right?....

It's possible USB protocol is being used. I had heard in another forum Neptune used I2C, but now that you mention it, the way devices "hot swap" would be perfect for USB protocol.
