ART.2206N BUS EXCHANGE DEVICE
The Art.2206N bus exchange device will only be tted in the 2291AB and 2291VB cabinets. It is a bus
exchange device which allows the VX2200 digital system to be expanded up to 998 apartments. There are
two applications in which this unit can be used.
The Art.2206N requires 12Vdc power and will be pre-wired in the cabinet directly from the 12Vdc output
on the VX123-A/VX123-V switching card. There are three sets of databus connections: bus out = BO, - : for
connection to the audio/videophones on the system; local bus = LB, - : for connections from the local entrance
panels (these databus connections will be pre-wired from the bus output on the VX123-A/VX123-V switching
card) : main bus = MB, - : connection from the main databus (these bus connections will come directly from
any main entrance panel and are not pre-wired). There is a busy terminal BS to connect to the local entrance
panel BS/BSY connection. The video terminal connections; V/V1, V2 : for connections from the main entrance
panel and out to the next Art.2206N in line; V/V1P, V2P : amplied video signal output connections to the
videophones of the block; V/V1L, V2L : video signal connections from the local entrance panel; V/V1O, V2O :
video signal output to the videophones of the block.
The rst application is on a system with both main entrances and sub/block entrances (main entrances can
call all apartments on a system and sub/block entrances can only call the apartments in their own block). For this
application only one Art.2206N would be required for each block.
The second application is a single level system with up to 10 entrances whereby all entrances need to call all
apartments and there are more than 180 apartments. In this application an Art.2206N would be required for
every 180 apartments on the system and could be used to expand the system up to 998 apartments (e.g. 500
apartments would require a minimum of three Art.2206N bus exchange devices).
Art.2206N Operation
In standby mode: the bus signal from the local entrance terminals LB, - are linked to the BO, - terminals (bus
out), while the video signal of the V1/V1L and V2L coming from the local entrances are sent to the video
output terminals V/V1O and V2O (video signal output to the videophones).
During the call: when a call is made from a main entrance, it sends serial data to communicate with the
Art.2206N (based on the Art.2206N’s address). If BS (local busy) is high (12Vdc = not busy) on the Art.2206N, the
call will be put through to the block and the system connects the BO, - terminals (bus out) with the main bus
(main bus entrance terminals MB, -) and also connects the video outputs V/V1O and V2O to the main video
signal input V/V1 and V2, thereby connecting the main entrance with the apartment required. If the BS is low
(0V) and the local entrance already has a call in progress then the main entrance will receive a busy signal
and must wait until the call from the local entrance has nished.
If a call is made from the local entrance while the main entrance call is already in progress to that block, the
local panel will get a busy signal and must wait for that call to end.
Programming using SW1 Dip-Switches
The Art.2206N programming and setup is carried out using the SW1 series of dip-switches. It consists of the
following settings:
• Unit Address (switches 1 - 4): The unit address, from 1 to 15, is set by using dip-switches 1 to 4
(refer to the table below).
• Operating Mode: The operating mode is set using dip-switch 5 and there are two operating
modes. The standard operating mode (dip-switch 5 = OFF) is used when a local block door panel is
connected to the Art.2206N. The other operating mode (dip-switch 5 = ON) is used when there is
no local block door panel connected and the system requires more than 180 users (this mode can
also be used on smaller systems with a single entrance).
