Chapter 3— Operating the Terminal in a Network
52
Trakker Antares 242X Handheld Terminal User’s Manual
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 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.
Choosing a Communications Protocol
After you connect the 242X 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 port.
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. 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
Configurable Protocol
Configurable protocol is based on Intermec’s Polling Mode D protocol
except that you have the option to change some of the serial port protocol
parameters or remove specific events from the protocol, such as poll or
handshake.
