2–14 Configuring your Reader

Publication 2755-6.14

Output/Package Detect Type Description

AC output Duration (sec)

The value entered here determines how long the

Output/alarm output remains active.

Delay Time before activating AC

output (sec)

The value entered here determines how long the

reader delays after its normal activation time before

acivating the output. The default value of 0.0 should

be sufficient for almost all applications. Use this

option only if it is impossible to mount the reader at

the Output location.

Enable programmable ‘No Read’

message

When this option is enabled, you will be able to

program your own no read message. The message

can be up to 10 characters long and can include any

of the human readable ASCII set (20h to 7fh). Note

that the message is right–justified when transmitted

from the reader. If this option is being used with

Wand Emulation output, the reader defaults to output

as Code 39 so the message must be within the

normal Code 39 range of characters.

Retain same symbol timers after

package detect cycle ends

Under normal Package Detect support conditions, the

reader resets scan buffers after a complete sensor

cycle. Same symbol timers prevent multiple reads

during the scan cycle. But as soon as the cycle

completes and the next Package Detect is

recognized, all buffers are cleared and the reader

scans any bar codes in the field. When retain same

symbol buffers with Package Detect is enabled, same

symbol timers do not automatically reset after a

completed sensor cycle. Rather, they reset after the

same symbol timer times out. This feature can be

useful under these 3 conditions: packages are spaced

relatively closely, the bar codes on consecutive

packages are the same and the possibility of a

package triggering a Package Detect while the box is

still in the scan field exists.

Save read and match bar code if

power–down

Under normal operations, when read and match mode

is used, a new read and match bar code is stored

immediately after the reader has been powered–up or

after the reader has been programmed through

StrataSet. When save read and match bar code on

power–down is enabled, the read and match bar code

is saved during a power-down, and a new read and

match is only accepted after programming the reader.

Support dual package detect

inputs

When this option is enabled, the reader uses the

current line sensor ALARM input as the second

Package Detect input. The current line sensor input

acts as the start of activation cycle, and the second

Package Detect input acts as the end of activation

cycle.
