Using Serial Communications on the Terminal
The 2475 has a serial port to transfer data to and from another device,
such as a printer, using serial communications. Before you can use serial
communications, you must perform these steps:
1
Install the 2475 and connect the terminal to a serial device. For help, see
the
Trakker Antares 2475 Vehicle-Mount Terminal Installation
Instructions (P/N 072512).
2 Choose a communications protocol. For help, see the next section,
“Choosing a Communications Protocol.”
3
Configure the serial port parameters for the particular communications
protocol. For help, see Chapter 2, “Configuring the Terminal.”
Depending on the protocol you choose in Step 2, you must set some or all
of the serial port parameters to have the terminal communicate with a
serial device. The values you set for the terminal’s serial port parameters
must match the values set for the device’s serial port parameters.
Choosing a Communications Protocol
After you connect the 2475 to a serial device, you are ready to configure
the serial port parameters on the two devices. The terminal uses a
communications protocol, and the terminal’s built-in file operations use
XMODEM, XMODEM1K, or YMODEM to handle data
communications through the serial ports.
You can configure a different communications protocol for each COM
port. The terminal’s built-in file operations use XMODEM,
XMODEM1K, or YMODEM for file transfer.
Communications protocols determine exactly how data is transmitted
between the terminal and the connected device. Each protocol has
parameters you can set, such as baud rate and parity. Both the terminal
and the connected device must use the same protocol and parameter
settings to communicate properly. For help with protocols, see the
Data
Communications Reference Manual (P/N 044737).
Binary Protocol
Binary protocol has no protocol. Characters are sent and received without
being altered. The Data Link Escape character (DLE) is
not inserted
before any character, and DLE characters are not stripped out of the
incoming data stream. No protocol characters, such as EOM or SOM, are
added. Binary mode supports CTS/RTS flow control.
You can configure the following serial port parameters:
• Baud rate
• Data bits
