Configuration

Local On-Board Configuration

8937 Module

Two on-board jumpers are present on the 8937 module to configure module

formatting if not using the remote controls. Refer to

Figure 9 for jumper

locations on the module circuit board.

• 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 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 setting cannot be overridden by remote controls.
