Hi does any one work with the pro software on pdm 25 me is telling me for the password but i connected is telling me is on with the green plug in the bottom corner

I have several devices all happily communicating on a can bus. The PDM25 is one such device on that network. Whilst the PDM is powered ON, the traffic on the network is all fine. I can scope the traffic and see the waveforms are well formed and timings correct. However, if the PDM is powered OFF it takes down the network with it. The waveform is completely suppressed to zero, it vanishes.

The PDM is NOT configured with a termination resistor as the network already has two nodes configured with this, and the bus resistance is the required 60ohmns. Why is the PDM disrupting the network like this?

All other devices on the network can be powered up/down independently without disrupting the network. With the PDM off, it must be physically disconnected from the network before the other devices can operate again. This certainly isn't correct or expected behavior f…

I want to setup an automatic fuel transfer using the sensor calibration (FUEL_LEVEL) input. My goal is the fuel pump turns on when the calibrated fuel tank level reaches 4 gallons and off at 9 gallons. I am using the counter to make it work but is there a better way to achieve this without the counter?

on if

CAN keypad 1 Button 4 state equals true

Thanks

I'm strongly considering using a PDM15 with my project car but I have a question regarding items which always need to be functional regardless of the 'ignition 'state' of the car. As I understand it, it is not recommended to permanently connect the PDM15 ignition input to +12v as this drains the battery over time. Is there a way then to program the PDM15 for a hazard light function without the ignition terminal being connected to 12v?

Thanks,

Hi smart people,

I am working on an EV conversion, and I'm using speedhut CAN based guages. I have room for only one temperature guage (temp range 0-100 celcius), but would ideally like to have the option to see the temp on both the electric motor and its inverter.

Here's my current approach:

• The guage will only read one pre-defined CAN message, so I've defined two CAN outputs in the PDM config that will send the correct message to the guage when activated.

• I'm sending two different CAN messages from the motor / inverter (with different addresses (not the same as the message required by the guage) and I have successfully parsed the right data into the CAN output messages.

• I'm trying to use a PDM switch input (true, false) to specify which of the two CAN messages are sent to the guage.

Is there an application available to run on Apple IOS tablet to monitor outputs etc. or plans to create one?

Hi, I have asked this before, will there be a new firmware with improvements to the wakeup time for PDM15? It was not like this when I bought it, i think it was firmware 1..12 or something like that. Then a 2 second delay occured after it gets power, it´s very annoying Is there anything that can be done in the software to speed things up ?

Hi there brains trust, I'm converting a car to electric and I want to use the PDM 25 to implement a few safety measures. I'm hoping someone can guide me on how to configure my outputs on a PDM 25 for the following:

1. I want to ensure that the High Voltage system can't be activated unless the driver has their foot on the brake pedal.

2. I want to ensure that the driver cannot select forward or reverse unless they have their foot on the brake pedal.

I've tried using an AND function where HV out can't be triggered unless the HV switch has been on and the brake pedal is also pressed, but when the brake pedal stops being pressed, the HV system shuts down. I looked at counters and general functions, but could not work it out. Sadly the user manual gives no example that would help.

Has anyone found…

Hi folks,

I notice that in Downloads/Software there is a new PDM 15/25/35 manual issued June 25. The new version looks like a significant update to the older version (great), but it references a new software version for the configurator (1.1.7) with additional features, that I cannot find anywhere in the downloads section.

Is there new software with more features that I just can't find?
