Hello,
I own an Axon S215.
I want to use the RS232 interface with a 12V RFID reader.
How should I use the "GND" pin for RS232 on the Axon ? Do I need to use it ?

I use another reader (12V as well) with the RS485 interface, but this one has no "GND" pin.

Thanks !

Ok, I'll do it on the board then.
I'll take my chances communicating directly with the modbus tcp server instead of using Evok's layer.

Cheers,
Ronan

Hello,
I am currently using an Axon S215 with the Evok API enabled.
What I'd like to do is communicate with the Evok WebSocket API, from a remote client. The goal is to have no software to install on the box.

For the moment I have relays and digital inputs working well.
But I can't find a way to interact with the RS485 port, other than the setup (baud rate, etc...) request.

Is it possible to read/write with the RS485 port using default Evok API ?

Thanks,
