Modbus Server – DALI
TM
Intesis
Powering the device
A power supply working with any of the voltage range allowed is needed (check section 5). 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 DALI channel.
Connect + and – terminals of the DALI bus of your DALI channel to Intesis' DALI port. Bus has polarity, but most
DALI ballasts are polarity insensitive.
Having your DALI channel powered up, you can perform a quick DALI connectivity test by pressing Port A / Port B
buttons:
-
When pressing Port A / Port B button, a broadcast command that will toggle the ballasts between 100%
and 0% level will be sent.
-
After 30s timeout of not pressing the button, ballasts will return back to its original level.
DALI commands coming from Modbus will continue to be executed while doing this test.
Connection to Modbus
3.3.1 Modbus TCP
Same ethernet connection as for Mitsubishi's Centralized Controller is used. Connect the communication cable
coming from the network hub or switch to the Ethernet port of Intesis. The cable to be used shall be a straight Ethernet
UTP/FTP CAT5 cable.
3.3.2 Modbus RTU
Connect the communication cable coming from the Modbus network to the port marked as Port B of Intesis. Connect
the EIA485 bus to connectors B1 (-), B2 (+) and B3 (SNGD) of gateway's PortB. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
(without repeaters) connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. The
gateway has an internal bus biasing circuit that incorporates the termination resistor. Bus biasing and termination
resistor for EIA485 can be enabled for PortB by means of a dedicated DIP switch.
Connection to PC (Configuration tool)
This action allows the user to have access to configuration and monitoring of the device. Two methods to connect to
the PC can be used:
•
Ethernet: Using the Ethernet port of the Intesis.
•
USB cable: To connect the device to the PC, the USB cable supplied should be plugged to the USB Console
port.
