Card Overview
The following figure and discussions describe the jumpers and controls on the TRA-8206.
Figure 3.1 Card-edge Controls
1. Card Control (JP1)
Use JP1 to select whether the Output Mute and Output Channel Configuration jumper settings
are respected or ignored by remote control settings. Select one of the following options:
• REMOTE — the local jumper settings are ignored and the card is configured remotely.
• LOCAL — the local jumper settings are respected and card is controlled locally. The
card controls and status can be read remotely but not changed (default setting).
2. Loss of Signal (JP2)
Use JP2 to enable or disable the Loss of Signal option as follows:
• MUTE — a channel’s outputs will be muted if the input signal degrades to the point that
the input EQ can no longer guarantee error-free performance. When the red ERROR LED
is lit, the outputs will be muted.
If you have input channels set to any rate other than Auto
mode, we recommend this jumper position. The output of the card would then mute if an
incorrect data rate is applied to the input, or if the input signal became too weak for the
input equalizer to compensate.
• NO MUTE — a channel’s outputs will work to the limits of the input stage (default
setting).
3. Channel A Rate Selection (SW1)
Channel A has a rate selection button and corresponding SD and HD LEDs. Use the rate selection
button and LEDs to set the input signal rate type that Channel A will process. Pressing the button
cycles between the HD and SD options. You can choose between the following signal rate types:
• HD — Select this option when using 1.485Gbps rate.
• SD — Select this option when using 143, 177, 270, 360, and 540Mbps rates.
4. Channel B Rate Selection (SW2)
Channel B has a rate selection button and corresponding SD and HD LEDs. Use the rate selection
button and LEDs to set the input signal rate type that Channel B will process. Pressing the button
cycles between the HD and SD options. You can choose between the following signal rate types:
1) Card Control (JP1) 4) Channel B Rate Selection (SW2) 7) BNC 2 and 4 Output Configuration (JP3)
2) Loss of Signal (JP2) 5) Channel C Rate Selection (SW3) 8) BNC 3 and 5 Output Configuration (JP4)
3) Channel A Rate Selection (SW1) 6) Bootload Button (SW4) 9) BNC 6, 7, 8 Output Configuration (JP5)
Note
— This setting applies to control of the jumpers only. Card-edge buttons and
switch settings can be configured remotely or locally in either setting.
