Videx 2206V Video block exchange device

Video block exchange for use with level systems with main entrances and clock entrances. (One per internal block) The 2206V is an electronic BUS exchanger controlled by the “Busy” link signal of the 2202 and 2203 front panels or the 2210 Concierge panel. By using this device (1 each block entrance), it is possible to have “main entrances” and “block entrances” on the same “2 wire BUS” (in this way the system can have one or more semi-independent lines or multiple speech paths). This device switches the “Main BUS” (from the main entrance) and the “Local BUS” (from the block entrance) to the "BUS out" which is connected to the apartments according to the source of the call. For video intercom applications, (4 wires no-coax for video intercom systems locally supplied or 6 wire for centrally supplied). The circuit is built into a 9 module DIN. It incorporates a 4 way Dip- switch to be configured according to the number of phones connected to the output.
