Transmission terminator / Timeout Value

 

When CPS Barcode Wedge reads terminator character on COM port it will consider that barcode scanner is signaling end of transmission and any data already in input buffer will be sand to log subsystem.

Terminator can be any integer value ranging from 0 to 255, which represents the ASCII code for the character or timeout value. 

 

When read timeout is selected as terminator, CPS Barcode Wedge will wait interval between two sequential characters to exceed ‘Read Timeout’ value, and then it will be considered as an End of transmission.

Folloving are examples of valid terminator selections:

 

 

 

If terminator is not TIMEOUT value but some ASCII char(s), CPS Barcode Wedge will wait for those characters to be received on COM port indefinantly or for timeout value. If Read Tiemout is set to 0, CPS Barcode Wedge will wait indefinantly. If timeout value is greater than zero, CPS Barcode Wedge will wait for terminator characters for timeout value after last read character. If no character is received after timeout interval, it will be considered as ‘end of transmission’ and any data already in input buffer will be passed to log subsystem.
