Choosing a Communications Protocol

Trakker Antares 241X Handheld Terminal User's Manual

2 Choose a communications protocol. For help, see the next section,
"Choosing a Communications Protocol."
3 Configure the serial port parameters. For help, see Chapter 2,
"Configuring the Terminals."
Depending on the protocol you chose in Step 2, you must set some or all
of the serial port parameters to have the terminal communicate with a host
computer or serial device in a wired network. The values you set for the
terminal's serial port parameters must match the values set for the host's
(or other device's) serial port parameters.
After you connect the 241X to a host computer or other serial device,
you are ready to configure the serial port parameters on the two devices.
The terminal uses a communications protocol and 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
• Parity
• Stop bits
• Flow control
