Note: You can continue running an application on the TRAKKER Antares terminal
while configuring the terminal from the host. If you send a configuration command that
changes the serial port parameters, you may not be able to continue sending commands
unless you also reconfigure your host.
To set up the application
•
Prepare and write a host application that can send transactions to and receive
transactions from the terminal in this format:
[ SOM] [ TMF field] configuration command EOM
where:
[SOM] is the start of message field.
[TMF field] is only used if you are using the Configurable protocol
and the Configuration Commands Via Serial Port are
enabled with TMF (Terminal Message Format). It is a
2-byte field containing one of these values:
CG
Configuration Get request sent from the host
application.
Cg
Configuration Get response sent from the
terminal to the host.
CS
Configuration Set request sent from the host
application.
Cs
Configuration Set response sent from the
terminal to the host.
Note: If the Configuration Commands Via Serial Port
are enabled without TMF or you are using a protocol
other than Configurable, do not include this field.
configuration command is the reader or configuration command or commands
you want to set on the terminal, or get the current value
of from the terminal. To save configuration changes in
flash memory, send the reader command
.+1
as the last
command.
For a list of commands, see Chapter 7, “Reader
Command Reference” or Chapter 8, “Configuration
Command Reference.”
EOM is the end of message field.
Note: To send data to an application instead of sending configuration commands,
use the letter
A
followed by a space in the TMF field. If the TMF field does not
contain CG, Cg, CS, Cs, or A, the terminal ignores the transaction.
