8937/8937D — Instruction Manual 23
Configuration
8937D Module
Three onboard jumpers are present on the 8937D to configure module for-
matting. Refer to
Figure 10 for jumper locations on the circuit board.
• DA 2 BYPASS/270 Mb/AUTO – for DA 2, set jumper J5 for AUTO
(pins 1-2) to enable auto reclocking (for signal data rates of 143, 177,
270, and 360 Mb/s), 270 Mb only (jumper pin 2 only), or BYPASS
(pins 2-3) to bypass reclocking (for signals with data rates of 50 Mb/s
to 360 Mb/s). This jumper setting can be overridden by remote controls.
• DA 1 BYPASS/270 Mb/AUTO – for DA 1, set jumper J6 for AUTO
(pins 1-2) to enable auto reclocking (for signal data rates of 143, 177,
270, and 360 Mb/s), 270 Mb only (jumper pin 2 only), or BYPASS
(pins 2-3) to bypass reclocking (for signals with data rates of 50 Mb/s
to 360 Mb/s). This jumper setting can be overridden by remote controls.
• Local/Remote – set jumper J7 to LOCAL (pins 1-2) to lock out remote
control or LOCAL & REMOTE (pins 2-3) for access to remote control.
This jumper setting cannot be overridden by remote controls.
