Powering the device
A power supply working with any of the voltage range allowed is needed (check section 4). Once connected the RUN
led (Figure above) will turn on.
WARNING!
In order to avoid earth loops that can damage the gateway and/or any other equipment connected to it,
we strongly recommend:
•
The use of DC power supplies, floating or with the negative terminal connected to earth.
Never use a
DC power supply with the positive terminal connected to earth
.
Connection to Modbus
2.2.1 Modbus TCP
Connect the communication cable coming from the network hub or switch to the ETH port of Intesis. The cable to be
used shall be a straight Ethernet UTP/FTP CAT5 cable.
2.2.2 Modbus RTU
Connect the communication cable coming from the Modbus network to the port marked as Modbus of Intesis.
Connect the EIA485 bus to connectors A (B+), B (A-) and SG (SGND). Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, and in each end of the bus it must be a termination resistor of 1
20 Ω.
Connection to the configuration tool
This action allows the user to have access to configuration and monitoring of the device (more information can be
found in the configuration tool User Manual). One method to connect to the PC can be used:
