Refer to section “Configuring the serial port” on page 52.
Configuring the serial port
This section defines the configuration options available for the serial interface on the Model 3086FR. This
information could be used to configure the V.35 or X.21 interface available on the unit.
Configuration variables available
Click on Serial > Configuration to configure variables. The following variables are configurable through the CLI
or web interface on the unit.
Clock Mode
Determines the source of timing for the unit.
• Internal: The unit will generate the appropriate clock speed defined by the speed setting of the interface.
• External: The unit will accept the clock from the interface and will use that clock to receive and transmit
data across the interface
Clock Invert Functions: (rxClkInv – receive clock, txClkInv – transmit clock)
Setting this variable will invert the appropriate clock at the interface. This should only be used under direction
of Patton Electronics technical support in order to trouble shoot system installations. Possible settings include
both normal and inverted
Speed
The speed setting function will determine the clock rate that will be used by the interface. Appropriate settings
include any n x 64K speed setting between 64–2048 kbps.
CLI Configuration Methods
The following section defines how to configure the serial interface using the CLI. All serial interface functions
are available under the “serial” directive of the CLI.
