settings of the task package or the

task configuration (.VCF) file)

Definition Options

Character length

(xxxWordLength)

A character oriented device takes a group of bits, one after

the other, and interprets them according to a standard. The

standard typically used is ASCII (American Standard Code

for Information Interchange). Typically ASCII requires a

minimum of 7 or 8 bits to represent characters.

5, 6, 7 or 8

Speed

(xxxBaud)

Devices can also transmit data at varying speeds or bits-per-

second (bps). This is sometimes referred to as “baud” after a

French engineer, Jean-Maurice-Emile Baudot, who devised

a system to measure the speed of telegraph transmissions.

Allowing for a bit or two of overhead, the number of

characters transmitted per second is roughly equivalent to

the bits-per-second divided by 10. A transmission of 9,600

bps is approximately 960 characters per second.

50, 75, 110, 150, 200,

300, 600, 1200, 1800,

2400, 3600, 4800,

7200, 9600, 19200,

31250, 38400

Parity

(xxxParity)

To prevent errors in transmission, parity may be used in

communication. When used, the parity adds one bit to the

data being transmitted and requires that the bit be set as

follows:

None – no parity bit is used

Odd – the sum of all bits plus the parity bit will be odd

Even – the sum of all bits plus the parity bit will be even

Mark – the parity bit will always be 1

Space – the parity bit will always be zero

1 (none)

2 (odd)

3 (even)

4 (mark)

5 (space)

Stop Bits

(xxxStopBits)

A bit that is always set, used to indicate end of a sequence. 1 or 2

(xxxTermChar1)

(xxxTermChar2)

Used to indicate end of input or line. Typically this is the

sequence of codes for carriage return (move to beginning of

line) and line feed (new line). The hexadecimal values for

these are 0x0D and 0x0A respectively.

Any ASCII code

expressed as “0xYY”

where YY is the

hexadecimal value of

the code

Power

(BarcodeKeepPowerOn)

VoiceClient 3.0 or earlier only

To conserve power, the computer provides power to the

barcode port only when explicitly needed. Some barcode

devices may react slowly on power-up, or may require that

power be kept on for the duration of the work assignment.

This parameter overrides the default power saving behavior

and supplies power to the port.

0 = no (default)

1 = yes

Power

(BarcodePowerOnTaskNode)

VoiceClient 3.1 or later

To conserve power, the computer provides power to the

barcode port only when explicitly needed. Some barcode

devices may react slowly on power-up, or may require that

power be kept on for the duration of the work assignment.

This parameter overrides the default power saving behavior

and supplies power to the port.

0 = enable power when

terminal is on

1 = enable power only

when scan requested

(default)
