When a second balanced audio expansion card is installed, channels 5 and 6 are used. The
second card is installed in the vacant module slot and connected to the first card and the
motherboard by a 3-connector cable, rather than the 2-connector cable used with a single card.
The second card enables Channels 5 & 6 when the jumpers are set to the “Non-dotted” position.
Labeling this card is done like the first card, except it will be labeled [CH 6 CH5].
2.6.2 Sync or ASI Output Data Card Jumper Configuration
When you install one SYNC or ASI expansion card, set jumper J9 on that card to the “dotted”
position. See Section 2.6.1 for details on “Dotted” and “Non-dotted” jumper positions.
When installing a second SYNC or ASI expansion card, jumper J9 on that card must be set to the
“non-dotted” position. Leave jumper J9 on the first data expansion card set to the dotted
position.
* * * Caution! * * *
When 2 SYNC or ASI expansion cards are installed, one must have the jumpers
in the dotted position, and the other must have them in the non-dotted position.
Failure to correctly configure the jumpers WILL cause operational problems.
