JANUS 2050 Vehicle-Mount Computer User’s Manual (4MB)
G-20
Reader Services
A collection of programs on the device that decode bar codes, process data
input and output, configure the device, and handle power management.
records per block
The maximum number of data records transmitted per block of data. A block
of data is transmitted during a single transmission event.
regular label
A bar code label that takes the form of <start code data stop code>. A regular
bar code label is executed as soon as you scan it. Contrast with multiple-read
label.
remark out
When you add a REM statement (short for REMark) at the beginning of a
command line in a batch file, DOS treats the line as a remark instead of as a
command. Any statement beginning with the characters REM will be ignored
by the command processor. Typically, users will remark out device drivers in
AUTOEXEC.BAT and CONFIG.SYS startup files.
REQ
Request for Acknowledgment character. Sent by the device to the host to
request a retransmission of an acknowledgment to a message.
RES
Reset character. Sent by the device to end communications with the host. The
RES character enables or disables the reset event, or resets the data
transmission event to the solicitation event.
resume
When you press
q
to turn the device back on, the device resumes exactly
where it was when you turned it off. If a program was running when you
turned off the device, the program continues running from the same point
when you turn the device back on.
RF data collection system
Radio frequency data collection system in which the individual components
communicate with each other by radio signals.
RFPH
The RF protocol handler, which enables a JANUS device to communicate as an
end device in an RF network. RFPH lets the device transmit and receive data as
specified by the RF communications protocol.
