Can bus keypad issues with Holley Term X

Hey everyone,


I am having a weird issue where my keypad (Blink Marine 12) seems to become disconnected from the PDM. The keypad stays lit but the buttons no longer function. I do not have a termination resistor at the keypad (I know this is not ideal since it is at the end of the canbus), but with the Terminator X handheld hooked up for datalogging and the Holley usb cable the resistance between the Can Hi and Can Low is already 53 ohms. Does anyone now if the lack of resistor could be the problem or is this a setup issue? I really appreciate any advice!

It’s possible the handheld or usb cable has a resistor in it. You want the bus to be at 60ohms. You may have too many.

Just eliminating the obvious, but you are clicking the "Retrieve" button after connecting?

No tripped option in the outputs


How come I don't show a tripped option on the outputs, the tripped count doesn't seem to do anything.

1.1.6 has an issue with this. If you need it, let me know and we can send the 1.1.7 pre release which has this fixed. you can get around it by using a generic function output x status > 1 Then use that in the fault LED condition.

Permanent Power and CANBUS

I have two PDMs and I intended to leave one permanently powered for things like central locking. The second would be powered on a switch along with the ECU.


I'm finding that the can bus doesn't connect properly unless I connect to the permanently powered pdm with the laptop.


Is there any way to get around this issue? I'm assuming that the permanently powered pdm is marking the bus as dead when it can't contact the other devices.

So I have re-wires the two PDMs and ECU to all turn on simultaneously on a switch, but the front pdm can bus must be running out before the devices in the rear are available.


The ECU and rear PDM establish can Comms, but the front pdm is dark until I resend the config.


I've checked the physical cabling and I get 60ohm with all devices powered off. I can only assume that the issue is on a micro second timing level.


The rear pdm and ECU are both in the boot and are fed by a longer cable run than the front pdm.


Is there any way to delay the start up?

12v on analogue input

I am looking to put a 12v input into my PDM25 v1and monitor that its voltage is at least greater than 5v. Checking the documentation I see the following ...



Just need to check that I read that as that I can add a 12v input but I can only measure up to 6v of that input ... would that sound correct or should I put no more than 6v into the input?


Thanks in advance

you can put 12V on it no problem, but it will only read up to 6V.

PDM configurator on Linux

Hello,

Do you think it is possible to have the PDM configurator working on Linux ? It seems to be developed with a cross-platform environment. It's boring to have a Virtualbox only to configure a PDM... Maybe, I can help for this.

Best Regard,

Integrated "AI Configuration Wizard" for Seamless PDM Setup

I have been working extensively with the PDM Configurator

and I would like to propose a transformative new feature:

an Integrated AI Configuration Wizard.

Configuring a PDM is often the most time-consuming and

error-prone part of a vehicle build. Users typically start

Start / Stop and indicators

After some research I have not manged to get any answers or at least recent answers as things change.

  1. Using a PDM25+and Canbus Keypad - I have two buttons left and right for indicators. Can you make the keypad button flash on / off like on a oem vehicle?

  2. I have the Start/Stop button set as momentary to start the car. All works fine. Are you able to set "something up" so when you press it again it stops, again like an oem vehicle.

Many thanks for your time.

for 2 - you need to check if the engine is running to determine what to do, you could have 3 states, press for ignition on, again to start and then again to switch off. When starting you need to ensure the starter is switched off when engine rpm reached a threshold or timer expires. It gets complicated very quickly. Not done this on Hardwire PDM though. Good luck!
