Module with galvanically isolated RS-485 interface.Isolation voltage: 1.5 kV The speed is up to 1 Mbit / s.
The module contains a 150 Ohm terminator between lines A and B. To enable it, you need to close the jumper on the top side of the board.
Pinout
RS485 signals go to extansion module terminals signed O1-O3.
Terminal | Function |
---|---|
O1 | A (D+) |
O2 | B (D-) |
O3 | Isolated GND (Common, C) |
Configuration
Configuration of the web interface is carried out in the section Configs => Hardware Modules Configuration.
No special configuration is required. You need to make sure that the corresponding slot (Internal slot 1 or Internal slot 2) is set to "None".
Operation
Port is available in the system as
- /dev/ttyAPP2 - when installed in first slot for expansion module (MOD1)
- /dev/ttyAPP3 - when installed in second slot for expansion module (MOD2)
For work you need to disable hardware flow control. Additional configuration port as the RS485 is required.
