base, but retains any bar codes that may have been saved in batch mode. After one
hour, the scanner powers off and batch mode data is lost. Refer to Auto Reconnect
Mode, page 105, to review other events that can start the relink process.
Example: Auto Reconnect Mode set to 1
Maximum Link Attempts set to 0
Relink Time-Out set to 10
Scanner Power Time-Out Timer set to 1800
Note: See Scanner Power Time-Out Timer on page 96.
The scanner attempts to connect to the base every 15 seconds, measured from one
attempt start to the next attempt start. After one half hour, the scanner powers off.
Host Acknowledgment
Some applications require that the host terminal (or server) validate incoming bar
code data (database look-up) and provide acknowledgment to the scanner
whether or not to proceed. In Host ACK Mode, the scanner waits for this acknowl-
edgment after each scan. Visual and audible acknowledgments provide valuable
feedback to the scan operator. The Host ACK functionality is controlled via a num-
ber of pre-defined escape commands that are sent to the scanner to make it
behave in different ways.
Note: System performance degrades when using Host ACK at rates lower than 9600 baud.
The following criteria must be met for the Host ACK to work correctly:
• The cordless system must be configured for Host Port RS232 (terminal ID = 000)
or USB COM Emulation (terminal ID = 130).
• RTS/CTS is defaulted off. You must enable it if the host system requires it.
• Host ACK must be set to On (page 109).
• A comma must be used as a terminator.
• The host terminal software must be capable of interpreting the bar code data,
make decisions based on the data content, and send out appropriate escape
commands to the scanner.
The commands to which the scanner responds are listed on page 110. The [ESC] is
a 1B in hex. A typical command string is [ESC] x,. [ESC] x is the escape command,
and the comma is the terminator, which is required.
Example: Commands may be strung together to create custom response sequences. An
example of a command string is listed below.
[ESC]4,[ESC]5,[ESC]6,
The above example will make a scanner beep low, then medium, then high.
Example: A good read beep is required for any item on file, but a razz or error tone is required
if the item is not on file. In this case,
