D-PRO Protection relay Technical Manual 21
4.7
The device is equipped with several communication ports for the connection to PC, modem,
networks, etc. The D-PRO protection relay is equipped with:

A B type USB connection to the PC for the FW update and the configuration of the
device parameters. See par. 4.7.3

A RS232 serial connection (max. 12M), see par. 4.7.1

A RS485 serial connection with galvanic insulation; the max. connection length in
optimal conditions is 1200m. The 120ohm terminal resistor is embedded; you can
insert it by connecting the JO pin 1 and 2. It requires the use of a shielded cable with
120ohm impedance (for example, BELDEN 3105A Multi-conductor-EIA Industrial RS-
485PLT/CM) See par. 4.7.2

A CAN-BUS connection to the DST4602 controller with galvanic insulation. The
120ohm terminal resistor is embedded; you can insert it by connecting the JQ pin 4
and 5. It requires the use of a specific shielded cable (e.g. HELUKABEL 800571).
See par. 4.8

A RJ45 connector for the Ethernet connection 10/100Mbps. See par. 4.7.4
For further details on the communication features, see the related parameters and the
document [3].
For the CAN-BUS connections, see documents [4] and [5].
4.7.1
The JP RS232 connector (serial port 1) can be used for the communication to an external
device equipped with RS232 interface, as a modem or a PC. The max. distance of the
connection is 12m.
The connection can be used for the configuration of the device parameters by means of the
BoardPrg3 program, or for the connection to a monitoring program as SicesSupervisor.
Below the specification of the connector:

JP_01: not connected

JP_02: RXD

JP_03: TXD

JP_04: DTR
