Selecting Output Interface

2.5.2 DEVICE NAME BROADCASTING

Device Name Broadcasting is selected by default. Deselect it to hide the scanner from

other Bluetooth

-enabled

devices such as PC or PDA. However, broadcasting must be

enabled for establishing an initial connection with other Bluetooth

-enabled

devices.

For example, you can disable device name broadcasting after successfully connecting the

scanner to WorkStation1. Such connection will be maintained automatically unless the

scanner is removed from the paired device list (called unpairing) by WorkStation1 or any

changes made to authentication and the PIN code. If you want WorkStation2 to connect

to the scanner, you have to enable device name broadcasting first.

Note: Device Name Broadcasting is selected by default (as it is required for initial

connection).

2.5.3 SNIFF MODE

This power-saving feature is selected by default for 1560/1562/1564/1660/1661/1664,

meaning the scanner will listen to the wireless network at a reduced rate.

Note: When connecting more than two scanners to a notebook computer or PDA with

Bluetooth

wireless technology, we suggest that you disable the power-saving

setting for a more reliable connection.

2.5.4 INTER-FUNCTION DELAY

By default, the inter-function delay is set to zero. Enter a value ranging from 0 to 254 by

the unit of millisecond to match the computer response time of the RS-232 interface.

Such delay time is inserted between every function code (0x01 ~ 0x1F) being transmitted.

The longer the delay time is, the slower the transmission speed will be.

2.5.5 ACK/NAK TIMEOUT

By default, the scanner sends data to the host without waiting for an ACK/NAK response

before sending more data. Set a value ranging from 1 to 99 by the unit of 0.1 second for

the time that the scanner waits for the host computer’s ACK/NAK response. If no

response is received before the specified timeout, the scanner will attempt to send the

same data three more times. If all attempts fail without any notification, data loss will

occur.

Note: We suggest that you enable the error beep so that you will be notified of such data

loss and have the scanner re-read the data.
