JA_09: not connected
To configure the use of the serial port 1 you need to configure the parameters
Parameter Description
P.0451 Use of serial port
P.0452 Modbus address
P.0453 Baud rate
P.0454 Settings
P.0470 Modbus registers order
The description of these parameters is found in document [3].
The device can be equipped with a serial portRS485 (serial port 2), which is galvanically
isolated and separated from serial port 1 (RS232), and which can be used to connect via
Modbus to a PC or other devices.
For details concerning the RS485 connection, its use and the programming of the parameters,
refer to document [3].
Connections:
•
JO-3 Connection RS485 A
•
JO-2 Connection RS485 B
The RS485 connection needs a 120-ohm termination resistor on both ends of the cable. The
device has the resistor built-in; to enable it, all you need to do is jumper connect JO-1 and JO-
2 to each other
You cannot connect a modem on serial port 2; as for the rest, you can use it for the same
connections as serial port RS232, using RS485/RS232 or RS485/USB adaptors where
necessary.
