Terminating resistance
If the VentoVind™ control unit is connected in a loop with several other RS485 units, take into
account whether the device is placed last in the loop or not. If the VentoVind™ unit is
not placed last
in the loop, remove jumpers 1,2,3 for RS485, as these jumpers act as terminating resistors. See
Wiring
diagram under chapter ”Control Unit
-
inputs and outputs”.
Setting ID address
.
To set the VentoVind™ unit ID number, adjust the Dip
-switch's rocker on the circuit board in the
Control unit. The Dip-switch's rocker is marked with numbers 1
–
8, where 1 represents the lowest
value zero or one, the 2nd represents zero or two, the 3rd zero or four, etc.
If all switches are positioned to zero (OFF) or one (ON) this gives = ID 3. VentoVind™ is usually
delivered with all switches in the OFF (ID=3) position. ID addressing is possible between 1
–
254.
The control unit's address on the 485 loop is set to binary using the DIP-switch as follows:
ID address example
ID 10 = Switches 2 + 4 in ON position.
ID 100 = Switches 3 + 6 + 7 in ON position.
Setting signal speed (Baud rate)
VentoVind™ is set to
Baud rate 19200 at delivery. Speed options: 1200, 2400, 4800, 9600, 14400,
19200, 38400, 56000, 57600, 115200. The Baud rate speed is set via the control panel's Setup menu.
