Command Reference Guide Serial Interface Configuration Command Set

invert txclock

Use the invert txclock command to configure the serial interface to invert the Transmit Clock (found in

the transmitted data stream) before sending the signal. Use the no form of this command to return to the

default value.

Syntax Description

No subcommands.

Default Values

By default, the serial interface does not invert txclock.

Command Modes

(config-ser 1/1)# Serial Interface Configuration Mode

Command History

Release 1.1 Command was introduced

Functional Notes

If the serial interface cable is long, causing a phase shift in the data, the transmit clock can be inverted (using

the

invert txclock

command). This switches the phase of the clock, which compensates for a long cable. If the

transmit clock of the connected device is inverted, use the

invert rxclock

command to configure the receiving

interface appropriately.

Usage Examples

The following example configures the serial interface to invert the transmit clock:

(config)#

interface serial 1/1

(config-ser 1/1)#

invert txclock
