respond to the input prompts. At the end of this procedure,
select the option that resets the PC COM port to match the new

Saving the Configuration
1. Before storing the new configuration in Flash, confirm that the
receiver has been configured to the desired settings.
Warning – Record the new serial port settings. If power is lost, this will
speed-up recovery. Alternatively, the receiver can always be returned to
the default configuration.
2. To save the configuration to Flash:
– Enter “=” to access the command list page for the 0x8E
command packet.
– Enter “s”, to send the 0x8E-26 command packet.
– Communication is momentarily suspended while the
configuration is being stored in Flash.
3. To confirm that the configuration changes have been saved,
turn-off the power supply and the battery back-up for a few
minutes. Then, power-up the receiver and confirm that the
configuration changes have been retained. Alternatively, you
can use Packet 1E to command a cold start.
Note – Command packet 0x8E-26 executes storage of various types of
receiver settings in addition to the port and protocol. See Table 3.2 for
a complete list of the settings that can be stored in Flash memory.
