Terms and Conventions
This manual refers to the JANUS 2050 RF Vehicle-Mount Data Collection
Computer as “the JANUS 2050,” “the computer,” or “the device.” The
following conventions are used to emphasize keypad and bar code input,
screen messages, command syntax, and warnings and cautions.
JANUS 2050 Keypad Input
Key icons represent keystrokes you enter on the JANUS 2050. For example, “press e
“ directs you to press the key labeled “e” on the JANUS 2050 keypad.
When you must press a series of keys in order, the keys are shown in order without
connectors. For example, “press caf.to boot the JANUS 2050” directs you to
press and release each key in the order shown.
When you must press more than one key simultaneously, the keys are shown
separated by a dash. For example, “press f- dto enter control mode.” When
keys are separated by a dash, you must press and hold them in the order
shown.
Bar Code Input
You can scan the bar codes listed in this manual to enter data or perform a
command. Each bar code includes the name and human-readable
interpretation. For example:
*$+*
Change Configuration
*$+*
Name
Bar code (Code 39)
Human-readable
interpretation
2050U.033
Screen Messages
When discussing messages displayed on the JANUS 2050 screen, the messages
are shown as in this example.
Error, too many
files exist in

Commands
• Command syntax is shown in the text as it should be entered into the
JANUS 2050. For example, to see a listing of directories on the JANUS 2050,
type the following command and press e.
dir
• Commands may be shown with special characters that are not part of the
command. Do not include the special characters when you type or scan the
command. These characters indicate information about each part of the
command.
Braces { } enclose a parameter that is required. For example, you format an
SRAM card with this command:
format {
drive:
}
where you replace {drive:}with the letter designation of the drive where
the SRAM card is located.
• Configuration commands use the convention data to indicate variable data.
For example, the configuration command for beep volume is:
BVdata
where data can be a number from 0 through 4. Replace the term data with
one of the options listed with the command syntax. For example, the
configuration command to turn the beep volume off is BV0.
• Bold type is used when keystrokes that you enter are included within
textual information. For example, “To load the protocol handler for COM1,
you would use 1” indicates you would press 1 on your keypad.
