Changing button functions without needing any physical changes is just one advantage of a PDM and keypad setup as Zac explains in this module taken directly from the PDM Installation and Setup course.

WHAT IS A PDM?
A power distribution module (PDM), power management unit (PMU) and power distribution unit (PDU) are all the same thing with different names, much like how variable cam control is called something different by each different car manufacturer.
Over the last few years we’ve seen PDMs become more popular and more affordable which means we’re seeing them pop up in more and more cars running at the grass roots level. These units replace the conventional fuses and relays we need to control and protect the various electrical circuits on our car with solid state electronics to control current flow. This dramatically simplified the wiring installation and can also improve reliability. With a conventional fused circuit, if the current is excessive then the fuse will blow to protect the components and you need to stop and replace the fuse to get going again.
With a PDM the fusing current can be adjusted in software and the unit will simply shut off the circuit if the fusing current is exceeded. The smart part however is that you can then configure the PDM to wait a specific amount of time before retrying the circuit that just failed. You can also set how many times the circuit will retry before failing permanently. This can often be enough to nurse a car with a failing electrical part back to the pits for repair. It’s also possible to log and display the current draw on each circuit so you can see exactly what’s going on with every part of the electrical system.
At this point, a PDM is still going to end up more expensive than using fuses and relays but when weighing up options most enthusiasts overlook the cost involved with mounting and wiring the relays and fuses. When you factor that in, upgrading to a PDM often isn’t going to cost substantially more and by the time you consider the advantages it can start to look pretty attractive.

    The PDM course will help you out if you're new to setting them up. There isn't a specific AiM example, but I am certain what is there will still help you out. Like ECUs, PDMs are all trying to do the same things at the end of the day regardless of the logo and if you have an AiM PDM with an AiM supplied keypad it should be super simple to get them communicating. Everything else from there PDM wise that you're new to, that's what the course is for. Hope that helps - Taz. www.hpacademy.com/courses/pdm-installation-and-configuration?

    I'm not sure we're qualified to answer that one sorry as our experience is pretty limited compared to say a paid professional driver who is using a lot of different setups. I can say we have never had to replace a keypad due to not liking it though so if that is anything to go off you're pretty safe regardless of the direction you take I reckon.

  • @hpa101

    The PDM16 as in MoTeC's PDM16? If so, then they have a marine version, PDM16M I believe, which would be the one you want. If you mean the PMU16 from Ecumaster which we use here, then I don't believe they have a waterproof version no. I would get in touch with your Ecumaster dealer to be certain, we don't sell any hardware so only know it in relation to what we use it for and discuss. Bit out of line with what we do at HPA for track cars etc, but I know some of the 4x4 guys just seal their electronics separately, as sealed in their own box rather than just relying on waterproof connectors which is fine for the water they see, but to be truely waterproof for a marine application etc I'm not sure I would do that myself - Taz.

    It looks very promising and I'm not sure I would be concerned about reliability even for my experimental aircraft, when you consider that the engine is already managed by an ECU with similar tech. But the price point is wayyyy too high unless you realy need the flexibility and control that hardwiring may not offer. No way a PCB keypad costs $300. That's obviously race stuff pricing. I'll wait for consumer electronics pricing.

    Depends on how you want to do your math. A $300 keypad, a connector and 4 wires is almost always more cost effect (always more cost effective if your paying someone to wire it) than wiring buttons in switches.

    @@SuperYellowsubmarin the cost of the PDM and wiring the outputs is a constant no matter if you wire switches or a can keypad. But by the time you purchase 8-15 toggle switches, terminals, heat shrink and wire and spend 4+ hours wiring your input switches it adds up quite quickly.

    It's hard to say you'll break even cost wise as it depends on a few variables, but you 100% save on time and wiring complexity. The price people put on that varies wildly according to who's doing the work and the work itself. That said it is now at a point where we can start to talk about the potential of either option being close in price where as previously there was no comparison to be made, PDMs were huge money. That is pretty cool and a good sign for things yet to come - Taz.

    You put these in things you dont want to have fail. You can run double redundancy to crucial components in the car and program fail safes to reset the circuit if "blown" If it fails again it can automatically switch to the second circuit ran. It's amazingly simplified for wiring as well. I'm in 1000%

    You've missed the point. You can set it up to do almost anything you want, and you're removing old school, failure prone fuses, switches and relays from the system. Yes it takes a while to setup, but it's flexible and saves a lot of hassle in the long run
