PDM 25 - User guide and firmware update?

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?

Hi, we are just getting things in place for the v2 PDM15/25/35 which will be released shortly. The software and firmware is not compatible with the current PDM15/25 model

Variable intermittent wipers

Hi all Trying to configure variable intermittent wipe on my PDM15 My windscreen washer switch is also a potentiometer for intermittent speed. I have this set as an input to my PDM but trying to figure out how to make it vary the intermittant speed is proving a challenge. Anybody done this before? If so any pointers on what I need to do to get the variable voltage from the potentiometer to change my intermittant speed? Cheers Matt

another easier option is changing the potentiometer out with a 4-position rotary switch with three different outputs and have each output of the switch trigger a different input on the pdm. then use those three inputs as your wiper speed triggers. the issue with doing it this way is you will take up two extra input signals.

Voltage Reading and Output Inconsistent

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?

HI Chris, Can you let me know exactly how you have the groud pin wired and also the ignition input?

Inconsistent voltage drop on start

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…

I can confirm my issue seemed to be related to be my cars stock keyed ignition cylinder that i was using. We switched over to using a toggle switch for 'key on' power and then a push button for starter. After switching to using that setup the issue was resolved.

Changer Keypad from J1939 to Canopen

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

Follow the video on our YouTube channel for changing the keypad baud rate. Then instead of sending the baud rate change command, send the j1939 to canopen command found in the keypad user manual

current cut off

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

u can also set in output parameters or under generic function create a line that says output x current < x. so u just select the output Ur wanting to monitor the current output of and add that in and add a < saying the selected output current is less than the selected output and add your amp limit to the far right box in drop menu. turn on the number box and turn off the middle drop-down menu

Key Pad

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.

yeah you will need to create a counter

First Time User of PDM25

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?

Hi, If the PDM is still in update mode, this means that the fw update was not successfull. It will stay in FW update mode until FW has successfully been loaded in. Please refer to the youtube video on our channel on how to do this

Changing states of Keypad

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.

183 Views

The best way to do this is to have the Keypad button mode as momentary.

Also set the off state and state 1 of the button to be output 1 status, and both green.


Then in the output function, Have it as

Output 1 on if

Keypad Button State Equals 1

OR

Output 1 State Equals 1

AND

Temperature > 60


This will latch the output on if the temp is > 60 when you press the button.
