4. 628 monitoring system is added on to an existing or new Video Duplicator which has some VCRs stacked 8 high or 10 high or even 15 high It is possible to programme the non volatile memory inside the VS 628 01 so that the up down counter for cabinet skips unconnected inputs level on the VS 628 24 interfaces For example if some VCRs are stacked 8 high then the VS 628 24 interfaces which connect to these VCRs would have only inputs 1 to 8 wired and in the case where the VCRs are stacked 15 high two VS 628 24 interfaces could be used One would have inputs 1 to 10 wired and the other would have inputs 1 to 5 wired or any other combination which adds up to 15 Of course two successive cabinet numbers displayed on the VS 628 01 would refer to one stack of 15 VCRS To set maximun level setting for individual cabinets make sure that Pole 2 and Pole 1 of the 8 pole switch inside the VS 628 01 is switched to ON position Next power up the VS 628 01 unit and while the word ADDR appears hold down Cabinet button and Level button together The display will then show C on the right hand side and a number on the left hand side Now press Lower Limit button The letter L will now be seen in the centre of the display with a 1 under Cabinet for Cabinet 1 and a number under Level which represents the current Maximum Level for cabinet presently indicated in this case Cabinet 1 11 The Maximum Level for any cabinet between 1 and the current Maxim
