Just finished installing PDM25 system, updated to 1.1.6 via usb beforehand, connected power and ground keypad lite up initially. Connected laptop to PDM, loaded input/output configurations I had made previously. When looking at system information, battery voltage started at 1.68 Volts and slowly went up to 5.61 Volts and never went past that. Measured voltage at input stud and 12v ign switch pin both reading 13v. Ground pin reads no resistance, even added ground direct to battery. Outputs are receiving same voltage, and therefore not powering on. Any ideas?

Utilizing PDM15. Checked all grounds and connections are good, battery has been charged and tested good. We were seeing an inconsistent voltage drop while monitoring battery voltage in the software. This would cause the pdm to power off and interupt startup sequence, sometimes i could get the car to start by holding the key down to start. Some times we saw a dip down to less than 1 volt while monitoring battery voltage in the pdm software. We were also using oscilloscope to do additional monitoring at the post of the pdm. The scope didn't see as big of a drop as the software was reading though (about 6v). Battery and grounds are all 0gauge wiring, and the car has a relatively simple setup. I also verified that we aren't tripping any of the set fuses to cause a shitdown. Anyone have any recommendations as to where we can go…

Hi Guys, so somehow I messed up and ordered my Blink Marine 12 buttons keypad with the J1939 protocol loaded in. I am able to see the Can data under the canbus analyser when I set my bitrate to 250kbps but the keypad show as disconnected and no buttons or LED is active. The ID in the analyser is 0x18EFFF21.

Using the CAN Transmit function of my PDM configurator, how can I change the Protocol from J1939 to Canopen? Keypad is the PKP-2600-SI model

for a motor, is it possible for the PDM25 to detect a current drop of X value for example and cut power to the output rather than blow the fuse?

a momentary input trigger should be able to latch the output on/off and when the current of end of travel occurs to just cut the output to 0v (obviously triggering the fuse will make the output not functional till pdm reset, i just want it to switch off the output until next trigger)

*power windows*

thanks

I have one of my Keypad buttons set up to start my car. I would like to know if there is a way to set up the same button to be used to shut down the engine?

I have the PDM controlling coils and fuel by a button and when it sees RPM. I would think you could add logic to turn off coils and fuel outputs if the RPM is above a specified # and the start button is pushed. Making it a Start/Stop Button.

Hi team, I am just getting set to upload my config file to my PDM25 and have attempted to update the firmware on the bench powered by USB. Once completed the update to 1.1.6 the PDM connects to PC again but stays in Firmware update mode according to the data in LH bar. The last step in update was to upload a blank config file but I left it for 20 mins or so and nothing was happening, just the circle of death. Where am I going wrong?

Is it possible to change the state of a buttons on the keypad? I want to set buttons for cool-down mode that will turn on water pump and fans until it has cooled down enough, then I would like this buttons to return to the off states.

We have installed 5 cars with PDM25 running the entire car. All of them runs ok, no issues at all

We install a new car, and in this case the PDM restarts at cranking, and it is related to the pdm because we move the pdm to another cars and the fault follows the PDM (wirings are exactly the same, so we just swaps the pdms between them). If i crank the car with the PDM connectet to the laptop, the car runs perfectly

Without the laptop connected, if i keep pushing the cranking button for 5-6 seconds, the pdm restarts and then, the car runs. I wanna know if the unit is defective, or maybe there is a firmware issue or similar.

Picture of the car just for attention

Hello. I have a weird issue. My car will only start when I connect my laptop to the PDM15. When the laptop is not connected I can hear the start seloniod click but it doesn’t crank. Is there a configuration update I can make to correct this?
