Pass-Through Mode
If the Module has been set to start up in pass-through mode, or is directed into pass-through
mode using the CLI command
pass
, it will transmit to the UDP target last defined with the
UDP Target IP Address
and
UDP Target Port
settings.
ƒ The UDP functions must be enabled via the CLI commands
Outbound Transmit
Mode
and
UDP Transmit Mode
.
The configuration must be saved to write the UDP settings to non-volatile memory and the
bridge restarted for the setting to have effect.
When the Host sets the Bridge for pass-through mode:
ƒ The
Serial Default
field set to
pass
causes the Module to transmit data to the
UDP Target IP Address
and
UDP Target Port
target. The module will also
broadcast the data if the
UDP Transmit Mode
is set to
bcast
or
both
.
ƒ
All data received on the serial port from the Host is sent to the
UDP Target IP
Address
and
UDP Target Port
target as UDP payload.
ƒ All data received from the LAN on the
UDP Listen Port
is delivered to the Host
on the serial interface.
Detecting and Executing the Escape Sequence
If the Module detects and executes the escape sequence from the Host:
ƒ The escape sequence is transmitted to the LAN application.
ƒ The Module sends an
OK
response to the Host.
ƒ The Host becomes the owner of the serial interface.
ƒ The Module processes data received from the Host as CLI commands.
Using Pass-Through Mode
The UDP functions are kept active until the Host breaks PASS mode.
