Addressing the BUS and setting its speed via dip switch
Note that the standard
speed
of the bus for VEDO control panels is 38400 baud.
The device address
must be unique and can only be programmed using dip switches.

OUTPUTS
O1
Open collector output 1.
Programmed as module Anti-Sabotage by default. The output is active when module sabotage occurs.
O2
Open collector output 2.
Programmed as module Low Battery Anomaly by default. The output is active when the programmed time has elapsed since
the moment at which the battery was no longer detected or the voltage at its terminals is 10.7 Vdc or 15 Vdc.
O3
Open collector output O3.
Programmed as module No 230V Mains Anomaly by default. The output is active when the programmed time has
elapsed since the moment at which the network was no longer detected.

* 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
Flashing slowly:
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.
DL3
On:
indicates that one of the Open Collector outputs is under protection due to a short circuit.
