Module with galvanically isolated RS-485 interface.Isolation voltage: 1.5 kV The speed is up to 1 Mbit / s.  
Module with galvanically isolated RS-485 interface. The speed of 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.

==Configuration==  
==== Operation ====
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 the first slot for extension module (MOD1)
* /dev/ttyAPP2 - when installed in first slot for expansion module (MOD1)
* /dev/ttyAPP3 - when installed in the second slot for extension module (MOD2)
* /dev/ttyAPP3 - when installed in second slot for expansion module (MOD2)




For operation you need to disable hardware flow control. Additional configuration of the port as the RS485 is not required.
Для работы необходимо отключить аппаратный контроль потока. Дополнительная конфигурация порта как RS-485 не требуется.
