4.1.4 Capital 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.

4.1.5 Alphabets 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.

4.1.6 Digits 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.

4.1.7 Inter-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.

The available options are listed below.
• No Flow Control
• Scanner Ready: The scanner will activate the RTS signal after power on.

• Inverted Data Ready: It is like the Data Ready flow control, but the RTS
signal level is inverted.
4.2.3 Inter-Character Delay

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