User Manual and Operating Guide

Receive Clock Jumpers: The receive-clock jumpers determine whether the external receive clock
for ports 0 and 1 is driven by:
 A remote clock
 The transmit clock divided by 16
 The transmit clock divided by 32
Note: If the transmit clock for port 0 or 1 is set as the input clock, the corresponding receive-clock jumper
(JP2 or JP3) must be set to the remote-clock position.
If the transmit clock for port 0 or 1 is set as an output clock, the corresponding receive-clock
jumper (JP2 or JP3) must be set to the divided-by-16 or divided-by-32 position.
The following shows the settings for the receive-clock jumpers.
