4.1.4Capital Lock Status

In order to send alphabets with correct case, the scanner needs to know the capital lock status of the keyboard. Incorrect settings may result in reversed case of alphabets being transmitted. There are 3 options to this parameter: On, Off, or Auto Detection. If this parameter is set to Auto Detection, the scanner will automatically detect the capital lock status of the keyboard before it transmits data.

4.1.5Alphabets Transmission

User can choose how alphabets are sent by this parameter configuration. The alphabets can be sent according to their case (the Case Sensitive option), or the case is ignored (the Ignore Case option) when transmitting.

4.1.6Digits Transmission

User can choose how the scanner transmits digits by configuring this parameter. The scanner can transmit digits by using the alphanumeric key or by using the numeric keypad. The Num Lock status of the keyboard should be ON if numeric keypad option is selected.

4.1.7Inter-Character Delay

An inter-character delay of 0 to 255 ms can be configured to match the computer response time of the keyboard interface. 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.

4.2RS232 Interface

User can select the desired, flow control, baud rate, parity, and data bits to be used in this output interface.

4.2.1Baud Rate / Parity / Data Bits

The supported baud rate, parity, and data bit are listed below.

•Baud Rate: 115200 / 38400 / 19200 / 9600 / 4800 / 2400 / 1200 / 600

•Parity: None / Even / Odd

•Data bit: 8 / 7

4.2.2Flow 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 waits for an active CTS signal. 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.

4.2.3Inter-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.

4.3USB Interface

A USB interface is also available. For installation instructions please refer to the separate diskette included with your scanner.

4.4Memory Parameters

The WWS800/850 reserves 4 KB flash memory as transmit buffer when the scanner is out of service range. Data will be saved into the reserved buffer when
