I have MAX485 board. MAX485 is a half duplex 485 IC. There are A&B pins.
The device which i should communicate it has the following pin diagram.

I think this is full-duplex interface. Can i communicate with it using MAX485?
Which pins of TEC3000 device should be connect to A&B pins of MAX485?
NOTE: TEC3000 waits a query like "*IDN?" and response immediately. Do i manage DE&RE pins for switching first TX mode after RX mode?

Installation diagram in the datasheet. There's no specific detail about half/full duplex usage.

What's a "TEC3000" and how does the manual say to connect it? – Justme May 11 '21 at 13:47
It doesn't say how to connect to MAX485 of course. It has RS485 to RS422 converter, but i don't have orginal converter. I add a installation diagram to my post. – Berker Işık May 11 '21 at 13:56

If remote is non-switchable FD then they cannot be combined into HD, then you need MAX488 at least – Tony Stewart EE75 May 11 '21 at 14:20
