Well I think I have a solution for my issues with the MXM module. My module stops working after 12 hours or whenever the lighting schedule restarts. Light groups (not created by me) would turn on and off at several min increments but at no time did I ever have 12 lights on at the same time.
I found that if I reset the MXM module, plug/unplug, then the MXM module kicked in within about 30 seconds and everything worked as it should.
So I have build the MXM point of sale FIXER Module. And you can build one too. It's fairly simple, requires only a couple of tools, and the parts were less that $30.
Here are the parts:
The Parts list is (2) 110VAC 4PST Relays ($9), 1 Set of USB A to Block Terminals ($9), 1 Project Box ($13), Some spare wire, 1 old electrical cord.
Tools Needed - Wire stripper, Phillips Screw Driver, couple of zip ties.
The relays are 4 Pole single throw. They have a NC (Normally Closed) and a NO (Normally Open position). We are going to connect the USB/Aquabus cable wires to the NC poles. This way the wires are always connected and the module is always on. When we apply power to the relay (using an Apex EB8 outlet to Reset it's own dumb module) the relay activates and severs the connection within the Aquabus/USB cable.
There are 5 conductors within a USB/Aquabus cable. I am sure if you spent some tinker time you could figure out which wires carry the aquabus power and just interrupt those 2 wires. But Neptune is so finicky and the purchase of the relay came with 2 relays that I decided to interrupt all 5 wires.
Printed on the Relay is a map of the wiring for the relay. Using a Giant Magnifying glass my old eyes followed the #s and connected all the NC poles of the relays. Using the different colored wire makes keeping it straight easier. There is almost no power on these wires so you can use fairly thin wire for this task.
I looped the wires from the Input Pole of the Relay to the NC Pole of the relay for each color to keep things straight during assembly.
Next step is to cut these jumpered wires we installed on the relays in 1/2 and connect them to the USB A to terminal block adaptors.
These lil adaptors come with their own mini screwdriver. Printed on the terminal block end are identifiers for each wire. These identifiers are for a standard USB cable. I don't know what each wire does within an Aquabus cable - but as long as the wire on one side connects to the same wire on the other side of the CUT we have created all will be well.
This is the final device completely wired up. Everything is functional and it could be used just as it sits. Total assembly time, including opening 3 Amazon bags and grabbing a few tools was just under 20 mins to this point.
The next step is optional. It's not needed but it makes for a little cleaner application. I installed the relays into a project box using a single screw and a small piece of din rail that is included with the relays.
I added zip ties to each of the cords. These are going to act as strain reliefs so if you or some mis-behaving child pulls on the wires it doesn't pull the wires out and stops the wire from being yanked out of the project box.
Drilling holes in the lip of the top of the box for the wires to pass thru took the most amount of time and skill. You have to make "U" shaped notches in the top lid of the box as a pass thru for the wire. It's not drilling a hole it's making a channel for the wire to lay in.
Once that part is done all that is left is to put the lid on and tighten 4 screws that lock the box together. I spent another 35 mins fiddling around with a label for the project box:
I have my Radions plugged into controllable outlets. There is no reason for the lights to be on 24/7 and I also have temperature interrupts so that is the tank temp gets too high the lights don't come on or turn off - My 1500g system has 750g outside in the heat of Los Angeles and we get temps up to 118deg. During this time of year sometimes the evaporative cooling struggles to keep things cool and we keep the lights off to be safe.
The MXM-point of sale Fixer module is plugged into an empty EB8 outlet.
The code for the outlet is
SET OFF
IF OUTPUT RADION_LT1 ON THEN ON
DEFER 00:05 THEN OFF
I may have to work on the outlet programming a lil more to dial in when the module is switched ON (which is actually turning the MXM off). I have 12 Radions on 6 different outlets and they are all staggered to turn on a minute apart so as to not put too much load on anything if they all turn on at the same time. The 6 outlets are spread across 3 EB832.
If you want to steal the label I made for mine - Go Ahead. Or Ask and I will send you a clean copy you can print for yourself--- LOL
