The RS485 interface can be configured to operate at the following Baud Rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200. It can
also be configured to operate with 1 or 2 Stop Bits and parity even, odd and none.
More details about the implementation of a Modbus devices network via RS485 can be found in the document "Basic RS485 and RS422 Con-
cepts", available on the website

ETHERNET CONNECTION
The Ethernet interface is located on the back of
DigiRail Connect
, as shown in
Figure 09
, and enables the communication of the device.

GALVANIC ISOLATION
DigiRail Connect
has galvanic isolation between functional sections of the internal circuitry to ensure that potential differences between parts of
the application system do not interfere with the proper functioning of the device, guaranteeing electrical isolation between them. The
DigiRail
Connect
galvanic isolation is shown in the figures below:
