Chameleon256 Routing Switcher
Jumper position 2 is used to identify a board as being a BALANCED AUDIO board. This is necessary for Balanced Audio boards because the maximum number of inputs on balanced audio main board is 64; inputs from 64 to 128 require an AUX board.
Jumper positions 3 through 7 are used to modify the card’s apparent position in the chassis to allow simultaneous switching of multiple cards, as with stereo audio or component video. With these jumper positions OFF each board has an address from 0 to 15; adding the jumpers modifies the card address as follows:
Position 3: ON=subtract 2 from the real address
Position 4: ON=subtract 4 from the real address
Position 5: ON=subtract 8 from the real address
For example, to have a card in the 9th slot (outputs 65-96) switch as though it is in the first slot (outputs 1-32), add jumper 5. To have a card in the 15th slot switch as though it is in the 9th slot, add jumpers 3 and 4.
