Addressing DIP and bus termination
DIP switches 1 to 5 are for addressing the reader on the bus. On the current version, only addresses 1 to 8 are used, so DIP switches 4 and 5
must be left on OFF.
485 line termination
If the RFID reader is connected as the
fi
nal point of the bus line, you need to connect a 120 ohm 1/4W 5% resistor in parallel to the 485 bus line,
i.e. between terminals A and B.

Mounting the RFID key reader on bus
To mount the RFID key reader, you need to use an interface plate for standard Keystone RJ45 sockets that is compatible with the residential
series you intend to use.
Simply connect the adapter to the plate and then plug the reader into the adapter, pressing it fully home until you hear the two parts engage.
RFID keys (art. SK9050x/A)
The keys are made using high-security, bidirectional RFID transponders.
The technology used is such that the keys can communicate with the reader without any need for electrical contacts and hence with problems
of contact wear. This ensures that performance remains high over time.
Used in conjunction with the RFID readers (on bus, on keypad, on Safetouch, on Minitouch or on Planux Manager), they make it possible to
activate and deactivate the system without any need for electrical contact. An RFID key can be associated to each user. Each key can operate
on the zones and areas for which the associated user is enabled.
They are available in various colours and their housing is shaped in such a way that they can easily be added to a bunch of keys on a keyring,
so that they are always to hand.
Setting RFID reader speed
IMPORTANT
: when
fi
rst powered up, the RFID readers on bus automatically set themselves to a speed of 38400 baud. To change the speed
proceed as follows:
•
With the device powered up, set DIP switch n°6 to ON. The LEDs on the RFID will light up until they are all lit, and will then all go off and start
lighting up again (learning mode)
•
In this state, set DIP switch n°1 and n°2 as shown in the table below to set the desired speed
•
Once you have set the speed, return DIP switch n°6 to OFF. The speed is now set
•
Set DIP switches 1 to 5 according to the address to be set, as per the paragraph below
Note that the standard speed of the VEDO switchboards bus is 38400 baud.
