Card Overview
This section provides an overview of the 9229-QS components.
Figure 2.1 Card-edge Components
1) CompactFlash™ Card 3) JP5, JP6
2) Board Reset Button (SW1) 4) Reference Termination (JP7)
1. CompactFlash™ Card
The CompactFlash™ card is reserved for future usage.
2. Board Reset Button (SW1)
Pressing this button resets the microprocessor and re-initializes the card. This is a hard reset of the card
and settings are not saved. This may cause loss of data and should only be performed as advised by
Cobalt Digital Inc. Technical Support.
3. JP5, JP6
These jumpers are not yet implemented and must be left in the default position of Pin 1 (top) and Pin 2
(center).
4. Reference Termination (JP7)
JP7 is a 3-position jumper block used to configure the 75ohm termination on the local analog
reference input on BNC 11 of the RM20-9229-C Rear Module.
ƒ Pin 1 (left) + Pin 2 (center) position — In this position, the analog reference is terminated
with an 75ohm resistor. This configuration is to be used for point-to-point cabling, or on
the last card of a daisy chain topology. This is the default position (Figure 2.2 ).
Figure 2.2 JP7 — Default Position
ƒ Pin 2 (center) + Pin 3 (right) position — In this position, the 75ohm terminator is
removed and the analog reference is not terminated. This configuration is used in a daisy
chain cabling topology where only the last card needs to be terminated.
Card-edge LEDs
This section describes the card-edge LEDs. Figure 2.3 outlines the locations of the card-edge controls.
