Note that the standard
speed
of the VEDO control unit BUS is 38400 baud (see table 4).
The device address
must be unique and can only be programmed using dip switches (see table 3).

guration jumpers
JP1
If activated, enables 485 BUS input terminal resistor*
JP2
If activated, enables 485 BUS output terminal resistor*
* Always remember to insert an end-of-line resistor between A and B of the 485 connection (using the relevant jumpers) to the two ends of the
main BUS line.
LED signals
DL1
Slow
fl
ashing:
no data transfer over BUS at the speed set using the dip switch.
Flashing quickly:
data transfer over BUS in progress.
DL2
Off:
the peripheral is communicating correctly;
Very slow
fl
ashing:
(approx. 3 seconds) no data package on the BUS.

Tamper contact connection
The
24H
terminal needs the Tamper contact to be connected in single balanced con
fi
guration. A resistance
of
1.8K
Ω
, in series with the contact, is required.
In the event of V+ V- power supply shortage, the auto-reset fuse intervenes. For the reset to take place correctly, the power supply must be
cut off for one minute.
ALARM
SINGLE BALANCED
To guarantee system certi
fi
cation, the isolator must be positioned in boxes protected by an anti-opening switch, or in the control panel
housing. The 24h input must be connected to a balanced line.
