Transmit Clock Jumpers: The transmit-clock jumpers determine whether the transmit clocks for ports 0
and 1 are an output (the data-terminal equipment provides the clock) or an input (the data-communications
equipment provides the clock).
The following shows the settings for transmit clock jumpers.
Receive Clock Jumpers: The receive-clock jumpers determine whether the external receive clock for
ports 0 and 1 is driven by:
Ÿ
A remote clock
Ÿ
The transmit clock divided by 16
Ÿ
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
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 must be set to the divided-by-16 or divided-by-32 position.
The following shows the settings for the receive-clock jumpers.
