Installation instructions for professionals
The ventilation unit can be controlled via Modbus as well.
There are two alternative Modbus connection methods
available. By using the X26 connector of the Modbus
RTU eAir motherboard. Or by using the Modbus TCP/IP
(md-sw version 1.30 onwards) with a X19 connector. The
connection method is selected in the settings wizard in
the eAir control panel, on the Modbus tab (eAir control
panel software version 2.07 onwards).
Modbus RTU default values
•
Modbus address 1 (1–100)
•
Communication form RS 485
•
Speed 19,200 (9,600 or 115,200) bps
•
Parity None (Even).
Modbus RTU X26 connection termination
RS485 X26 connector has options termination and
biasing. These are selected in the short-circuit block JP5,
which is right behind the X26 connection.
The below table shows the JP5 jumper. The bottom row is
closest to the X26 RS485 connector.
In the picture below you can see the placements of the
Modbus RTU and Ethernet / Modbus TCP/IP connections
on the eAir motherboard.
Modbus registers can be found on the Enervent website at
www.enervent.fi.
Installation to a Modbus
The Modbus TCP/IP connection method does not
allow any kind of authentication or encryption. The
unit must not be connected to a network that has
open access to public internet. At the minimum,
there must be a firewall that prevents external
incoming network traffic.
NOTE
[o o]
Biasing: Jumper installed = RS485 B line earthed
via the GND 600 Ω resistor.
[o o]
Termination: Jumper installed = bus terminated
[o o]
Biasing: Jumper installed = RS485 A line
connected via the +5V 600 Ω pull-up resistor
Modbus TCP/IP usage
