Apex controller -v- RKE
Apex controller -v- RKE
Several folks asked why I chose the new Apex controller over the RKE. Since I had never owned a controller before this tank, the only feature I could point to was internet control of the functions plus the iPhone application.
I found an interesting list of the other numerous differences on the Neptune forum and have copied it (with permission) for discussion...
Granted, the author of this list is understandably prejudiced toward the Apex... so don't take his opinions personally...
Here ya go:
"There is really no comparison between the two controllers. The RKE is inferior in just about every aspect. Here are some features in which the Apex system is better:
Looks better
Very attractive mechanical design
High Quality Display with excellent clarity/contrast.
- Costs less.
- Easy to use configuration wizards.
- Most expandable controller - up to 240 modules, thousands of outlets, hundreds of probes.
- backwards compatible with older AquaController accessories.
- More features - Some include:
more flexible/sophisticate configuration
season lighting control
season temperature control
- Integrated Ethernet (Optional $$$ on RKE)
- Monitoring & Control & configuration on the webserver.
- Only controller with web browser based configuration.
- XML support
- multiple head unit displays - not possible on RKE
- multiple sound alarms.
- Includes 6 digital inputs vs 2 on RKE.
- Galvanic Isolation on probes result in accurate readings. RKE has no isolation and has major interference issues.
- Includes built-in variable speed pump control. Not possible on RKE
- Includes built-in 0-10V light dimming. Extra on RKE
- Can name outlets, and modules - not possible on RKE
- ORP input is modal - can be ORP or pH input on Apex - not possible on RKE
- Default outlet state on Apex. On competition of a communication error occurs all outlets
just shut off - RKE just shuts everything off
- State of the Art 32 bit processor - not an 8 bit slow processor like RKE.
- 5 times faster than competitor's controllers
- 16 times more code space - much more expandable for future enhancements.
Not code space limited like the RKE
- 16 times more storage space for datalogs than the RKE.
- Bus interconnect can be starred or daisy chain configuration.
- Has Power failure detection/alarms/control - not possible on RKE.
- EB8 has power failure detection/alarms/control - not possible on RKE
- Don't have to disassemble controller to perform firmware upgrades
- Reliable/High Quality buttons (No unreliable capsense)
- Lowest cost per outlet control options
- Robust communications protocol Bus Interface with error correcting.
- EnergyBars have built-in AquaBus hubs - On RKE must purchase add-on.
- Built in virtual outlets. On RKE must purchase announced but not shipping PC1.
- Cable lengths can be much longer than RKE."
Apex just made its first firmware update and web page update available here on RC. After updating my OS, it was a breeze to install both updates while sitting at my computer.
All in all, I am very pleased with the Apex, and am not disappointed with the ability to control the tank system online from anywhere there is a computer... JMHO.
