When the scanner goes out of range, 15 attempts are made to link to the base unit
or Access Point. Each attempt consists of approximately 5 seconds of active time
followed by 3 seconds of idle time. After 15 cycles (8*15 =120), or about 2 minutes,
the scanner stops trying to connect to the base or Access Point, but retains any
barcodes that may have been saved in batch mode. After one hour, the scanner
powers off and batch mode data is lost.
Example:
Auto Reconnect Mode set to 0
Maximum Link Attempts set to 15
Other values at default setting
When the scanner goes out of range, no action is taken to relink. When the trigger
is pulled, 15 attempts are made to link to the base or Access Point. Each attempt
consists of approximately 5 seconds of active time followed by 3 seconds of idle
time. After 15 cycles (8*15 =120), or about 2 minutes, the scanner stops trying to
connect to the base or Access Point, but retains any barcodes that may have been
saved in batch mode. After one hour, the scanner powers off and batch mode data
is lost. Refer to
, page 72, 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
The scanner attempts to connect to the base or Access Point 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
).
