3.2 RS232 Interface
The user can select the desired, flow control, baud rate, parity, and data bits to be
used in this output interface.
3.2.1 Baud Rate / Parity / Data Bits
The supported baud rate, parity, and data bit are listed below.
Baud Rate : 38400 / 19200 / 9600 / 4800 / 2400 / 1200 / 600 / 300
Parity : None / Even / Odd
Data bit : 8 / 7
3.2.2 Flow Control
The user can further configure the flow (handshake) control method to be used. The
available options are listed below.
No Flow Control
Scanner Ready : The scanner will activate the RTS signal after power on.
After each good read the scanner will then wait for the CTS signal becomes
active. The data will not be sent until CTS signal becomes active.
Data Ready : The RTS signal will be activated after each good read. The
scanner will then wait for the CTS signal becomes active. The data will not
be sent until CTS signal becomes active.
Inverted Data Ready : It is like the Data Ready flow control, but the RTS
signal level is inverted.
3.2.3 Inter-Character Delay
An inter-character delay of 0 to 255 ms can be configured to match the computer
response time. The delay time configured is inserted between transmitting every
character. The longer the delay time configured, the slower the transmission speed
will be. The inter-character delay is zero by default.
3.3 USB Interfaces
Two USB interface models are also available and must be specified at time of
order. The ordered USB model type is indicated on the packaging.
3.3.1 Serial USB (Virtual Com):
The configuration of Serial USB scanner is the same as RS232 interface. For
installation instructions please refer to the separate diskette included with your
scanner.
3.3.2 HID USB:
The configuration of HID USB scanner is the same as Keyboard Wedge interface.
(3~5 ms of Inter-Character Delay is suggested when using HID USB interface).For
installation instructions please refer to the separate diskette included with your
scanner, only required for Windows 98. For Windows Me, Windows 2000 AND
Windows XP, no installation required. Just Plug in and scan.
