Command Reference Guide Serial Interface Command Set
invert rxclock
Use the invert rxclock command to configure the serial interface to expect an inverted receive clock
(found in the received data stream). 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 expect an inverted receive clock (rxclock).
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 (refer to invert txclock on page 1889). 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 receive clock:
(config)#interface serial 1/1
(config-ser 1/1)#invert rxclock
