•
Except the data link " D+" , " D-" and " GND" - connection may no further cable cores of
the data line be used.
•
Max. allowed wire length 1000 m (CAT5/7 500 m)

Bits = 8
Patity = Even (None, exception of devices agriculture)
Stop bits = 1
Handshake = none
Information
If any matters are unclear, please contact our V-STE support department for control systems -
ventilation technology. The information sheet "Network structure of Modbus" R-TIL08_01 contains
detailed information about Modbus.
5.14.3 LON
®
Bus system is possible via add-on module
Connection to the LON ® bus system is possible via add-on module type “ Z-Modul-L ” (Part-No.
380053). Communication to controller via the RS-485 interface, FTT-10A transceiver.
5.15 Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
earthed conductor. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50V (between “ GND ” terminals and “ PE ” earthed conductor). If necessary,
a connection to the earthed conductor potential can be established, install bridge between “ GND ”
terminal and the “ PE ” connection (terminal for screening).
