MS-4 Imager User’s Manual 7-5

I/O Parameters

Good Read

Note: A No Read can still be transmitted if Enabled.

When to Output Symbol Data

As Soon As Possible

Note: More than one decode might in fact be required to qualify as a good read, depending

on how Decodes Before Output is set.

End of Read Cycle

Usage: Good Read is used when an application requires all symbol data to be

transmitted. It’s typically used in tracking applications in which each

object is uniquely identified.

Definition: With Good Read enabled, the Imager transmits symbol data on any good

read regardless of Matchcode Type setting.

Definition: This command allows the user to choose when symbol data can be sent

to the host.

Serial Cmd: <K705,symbol data output status,when to output>

Default: As Soon As Possible

Options: 0 = ASAP 1 = End of Read Cycle

Usage: As Soon As Possible is useful in applications in which symbol data

needs to be moved quickly to the host, typically when the host is making

decisions based on symbol data.

Definition: Enabling As Soon As Possible causes symbol data to be sent to the

host immediately after a symbol has been successfully decoded.

Usage: End of Read Cycle is useful in timing-based systems in which the host is

not ready to accept data at the time that it is decoded.

Definition: Enabling End of Read Cycle means that symbol data does not get sent

to the host until the read cycle ends with a timeout or new trigger.
