The scanner attempts to connect to the host every 15 seconds, measured from one attempt start to the next attempt start.
After one half hour, the scanner powers off.
Communication Between the Scanner and the Host
When data is scanned, the data is sent to the host system. The wireless scanner provides immediate feedback in the form of a
"good read" indication with a green LED on the scanner and an audible beep. This indicates only that the bar code has been
scanned correctly.
When using an Access Point, the host also acknowledges when it has received the data. The wireless scanner recognizes data
acknowledgment (ACK) from the host. If an Access Point cannot determine that the data has been properly sent to the host, the
scanner issues an error tone. You must then check to see if the scanned data was received by the host.
Programming the Scanner and Host
When using the scanner and host together as a system, menu parameters and configuration settings are stored in the host. If
the scanner is not linked to a host, configuration settings are stored in the scanner.
RF (Radio Frequency) Module Operation
The wireless system uses a two-way Bluetooth® radio utilizing adaptive frequency hopping (APH) to transmit and receive data
between the scanner and the host. Designed for point-to-point and multiple point-to-single-point applications, the radio oper-
ates using a license-free ISM band, which sends relatively small data packets at a fast data rate over a radio signal with ran-
domly changing frequencies. This makes the wireless system highly responsive to a wide variety of data collection applications
and resistant to noisy RF environments. The communication range between the scanner and host, depending on the environ-
ment, is 33 feet (10m). See
System Conditions
The components of the wireless system interact in specific ways as you move a scanner out of range, bring a scanner back in
range, or swap scanners between two hosts. The following information explains the wireless system operating conditions.
Scanner Is Out of Range
The wireless scanner is in communication with its host, even when it is not transmitting bar code data. Whenever the scan-
ner can't communicate with the host for a few seconds, it is out of range. If the scanner is out of range and you scan a bar
code, the scanner issues an error tone indicating that there was no communication with the host. Refer to
Alarm, page 3-8 and
Scanner Is Moved Back Into Range
The scanner relinks if the scanner or the host have been reset, or the scanner comes back into range. If the scanner
relinks, you will hear a single chirp when the relinking process (uploading of the parameter table) is complete. Refer to
of-Range Alarm
Out of Range and Back into Range with Batch Mode On
Note: See
Batch Mode,
The scanner may store a number of symbols (approximately 500 U.P.C. symbols; others may vary) when it is out of range
and then send them to the host when back in range.
You will not hear a communication error tone in this mode, but you will hear a short buzz when you press the scan button if
the radio communication is not working. Once the radio connection is made, the scanner produces a series of beeps while
the data is being transferred to the host.
About the Battery
There is a danger of explosion if the batteries are incorrectly replaced. Replace the batteries with only the same or
equivalent type recommended by the manufacturer. Dispose of used batteries according to the recycle program for
!
batteries as directed by the governing agency for the country where the batteries are to be discarded.
