Selecting Output Interface
2.2.4 STOP BIT
By default, it is set 1 stop bit. Select 2 stop bits if necessary.
2.2.5 FLOW CONTROL
By default, there is no flow control in use. Select the flow control (handshake) method.
Options
Description
No No flow control
Scanner Ready
T
he scanner will activate the RTS signal upon powering on. After each good
read, the scanner will then wait for the CTS signal to become active. Data
will not be sent until the CTS signal becomes active.
Data Ready
T
he RTS signal will be activated after each good read. The scanner will then
wait for the CTS signal to become active. Data will not be sent until the CTS
signal becomes active.
Inverted Data Ready It works the same as the Data Ready flow control, except that the RTS
signal level is inverted.
2.2.6 INTER-CHARACTER DELAY
By default, the inter-character delay is set to zero. Enter a value, ranging from 0 to 254
in units of millisecond, to match the computer response time of the keyboard interface.
Such delay time is inserted between every character being transmitted. The longer the
delay time is, the slower the transmission speed will be.
2.2.7 INTER-FUNCTION DELAY
By default, the inter-function delay is set to zero. Enter a value, ranging from 0 to 254 in
units of millisecond, to match the computer response time of the keyboard 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.
2.2.8 ACK/NAK TIMEOUT
By default, the scanner sends data to the host without waiting for an ACK/NAK response
before sending more data. Enter a value, ranging from 1 to 99 in units of 0.1 second. If
no response within the specified period of time, the scanner will attempt to send the
same data three more times. If all the attempts fail without any notification, data loss will
occur.
Note: We suggest you to enable the error beep so that you will be notified of such data
loss and have the scanner re-read data.
