Polling Mode D Protocol
Polling Mode D requires the host computer to ask the terminal for data it may have
(polling) and to request to send data to the terminal (selecting). Polling Mode D uses an
RS-232 or RS-422 interface. Use Polling Mode D if you want to connect to a 900 MHz
network via the 9189 RF Gateway.
Here are the serial port parameters you can define:
•
Baud rate
•
Flow control
Configuring the Serial Port Parameters
The values you set for the terminal serial port must match the values set for the serial
port on the connected device. There are two ways to configure the terminal’s serial port
parameters:
•
Scan the configuration command from a Code 39 or Code 93 bar code label.
•
Send a command from a host application. For help, see the next section,
“Configuring the Terminal Via the Serial Port.”
The terminal only uses the parameters that are valid for the current protocol
configuration. For example, if you are using Configurable protocol on COM1, you can
set a value for poll, but the terminal will not use it if handshake is not enabled.
Once the terminal is connected and configured, you can transfer data between the
terminal and the device that is connected to the serial port. For help transferring files,
see Chapter 5, “Programming the Terminal.”
Configuring the Terminal Via the Serial Port
You can use an application on the PC or host to configure the TRAKKER Antares
246X terminal by sending commands through the serial port. For example, you may
want to change the Beep Volume command.
To send and receive configuration data, you need to write an application for the host
that can communicate with the terminal through the serial port. You must connect the
terminal to the host by using one of the serial ports.
Once the terminal is communicating, you can configure it. If you are using the
Configurable protocol, you must enable Frame mode and the Configuration Commands
Via Serial Port command to configure the terminal through the serial port. You cannot
configure the terminal through the serial port if you are using Configurable protocol
with no EOM or Binary protocol on that port.
