You could try to ask Sainsmart directly for documentation, although my experience with them has been quite disappointing in the past. But I wonder how people are supposed to use...

Well, segfault is not good. Let's try to find out what is happening. Unfortunately I don't have this type of card here. I implemented the driver with the help of...

Great, can you post the protocol specs here? Would be interested to have a look. For the driver integration look at the sample code `relay_drv_sample.c/.h` or the existing drivers. >...

Interesting. I think the bytes are the ASCII codes of the hex characters that are sent over the serial line. You can control the relay card via a serial console...

It might be worth asking Sainsmart for documentation. They will probably not understand what you are asking for but if they **do** provide some useful information it could save us...

Hi @kjatar, did you get any further with this? Were you able to check the response date from the relay card?

Hi @beaglebob , personally I am not working on this relay cards driver because I don't own that card myself. Don't know if @kjatar is planning to go ahead with...

Yes, if this is the complete C source code it should contain all the details we need to implement our own driver. At the moment I don't have any time...

Hi, the implementation of pump history handling is not working reliably in the cnl24driverlib. But this was fixed in the improved driver by @oldsterIL in [his repository](https://github.com/oldsterIL/600SeriesDriver). So starting from...
