All the models can be interconnected in a variety of ways. For example, two VS-1211 units become 24x1 or 12x2, etc. Three or four VS-1211 units, depending on whether the system is RGB or RGBS, become a 12x1 video component switcher. Finally, the video signal bandwidth is 225MHz (typical), which permits the switchers to be used in the most demanding applications. -

RCA type connectors located on the back of the unit. DIP SWITCHES, JUMPERS AND TRIMMERS Consider the VS-1211 as an example of all the switchers in the family. It switches video and balanced stereo audio simultaneously. As mentioned previously, there are three options for operating the switcher. All are available without removing the switcher cover. -
Page 12: Jumpers, Their Uses And Set-Up Requirements
The jumper locations are illustrated in Figure , and their functional operation is described below: Each switcher input has its own internal jumper. In the VS-1211, these jumpers are numbered J21 to J33 and they are factory located in the position that provides a 75ohm input termination. If the 75ohm termination is not required, the jumper must be relocated to its alternate position (floating on the pin remote from the input socket and not connected in any circuit). - Page 13 Figure : Location of Internal Jumpers KRAMER ELECTRONICS LTD.
