Hardware Overview
This chapter provides a general overview of the user controls available on the SPG-8260(-W) card.
Card Overview
The configurations outlined in this section should be performed before installing the card in the
frame, but may be repeated as required.

1. Bootload Button (SW3)
Use SW3 for factory service in the unlikely even of a complete card failure. Do not press this
button unless instructed to do so by Ross Technical Support personnel. Refer to "Bootload
Button".
2. Reference In/AES Out/Word Clock Out Jumper (JP2)
An AES/Word Clock output, or a local reference input, is also available on one of the bottom
BNCs. Depending on the card model and the rear module you are using, the AES/Word Clock
output or a reference input is available on BNC 9 (8310AR-030, 8320AR-030 rear modules), or the
bottom BNC (8320AR-031 split rear module). Use JP2 to select the function of BNC 9 (bottom
BNC).
For the SPG-8260, select from the following:
› REF IN — Select this option to enable the BNC to use the local reference input.
› AES OUT — Select this option to enable the BNC to output an AES signal or a copy of the Word
Clock signal.
› For the SPG-8260-W, select from the following:
› REF IN — Select this option to enable the BNC to use the local reference input.
› WORD CLOCK OUT — Select this option to enable the BNC to output a copy of the Word Clock
signal.
3. EXT TERM Jumper (JP1)
Use JP1 to terminate the signal on the Reference input when JP2 is set to REF IN. Select from the
following:
› ON — Select this option to terminate the signal on the card. Note that it is recommended to
select this option when JP2 is set to AES OUT / WORD CLOCK OUT.
› OFF — Select this option to leave the signal un-terminated (signal terminated externally on the
cable).
4. Function Select Switch (SW1), not shown
On legacy SPG-8260(-W) cards, use SW1 to select general functions and menu items and works in
conjunction with the Mode Select Switch (SW2). Refer to "Card-edge Menus" for details.
