The scanner attempts to connect to the base or Access Point every 15 sec-
onds, measured from one attempt start to the next attempt start. After one
half hour, the scanner powers off.
Host Command Acknowledgment
Some applications require that the host terminal (or server) approve or reject
incoming bar code data and notify the operator of these actions. These applica-
tions require that the host maintain control over the response indicators emitted
from the scanner. Turning on Host ACK configures the scanner to respond to
commands from the host system.
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 3-32).
• 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.
Escape commands are addressed to the scanner via “Application Work
Groups.” Once a command is sent, all scanners in a group respond to that com-
mand. Because of this, it is recommended that each scanner is assigned to
its own group in Host ACK mode.
The commands to which the scanner responds are listed on page 3-32. The
<ESC> is a 1B in hex. A typical command string is y <ESC> x, where “y” is the
application work group number, “<ESC> x” is the escape command, and the
comma is the terminator, which is required.
Commands may be strung together to create custom response sequences. An
example of a command string is listed below.
0<ESC>4<ESC>5<ESC>6,
The above example will make a scanner in application work group zero beep
low, then medium, then high.
Once Host ACK is enabled, the system works as follows:
• The scanner reads a code and sends data to the base or Access Point to
transmit to the host system. No audible or visual indication is emitted until the
scanner receives an escape command. The scanner read illumination goes
out when there’s a successful read.
