RS-485 modbus enable

I would like to enable modbus-rtu by enabling RS-485 communication of "SBL2360".
I tried the wiring according to the manual but there is no response.
And what does the meaning of the "^ DMOD 0" command mean to use modbus-rtu?
Can USB communication and rs-485 be used at the same time?

Hey, Sorry I missed this post. We do not support modbus RTU on our controllers, only Modbus ASCII. The controller cannot mirror the ports, but it should be able to use them both concurrently.

I am actually not sure what DMOD does, and I will have to consult with our firmware engineer. I will let you know if I get an update.

Is modbus-RTU applied in roborun v2.0?
I have read the updated document.

When will it be released?
Which products will be applied?

I am pretty sure we do not support any form of Modbus RTU, no matter which firmware.
