For data scanning purposes, AlphaSense looks at the data coming to it as a "block". Data is gathered continously, until an EOB ("end-of-block") character is received. To understand this, imagine the data to be a continuous stream, and the EOB character serves as a knife to chop the data into block sections. Each section, when received, is then analyzed according to the user matchstring rules. The EOB character is defaulted to the "return" character, since that is the most useful, and parses the received data line by line, as it would appear on a printer. Most all user never need to change this value. If you want to provide for multi-line capture, or your data has some other format where a "return" does not break up the data in the manner you wish, you can customize how AlphaSense parses the data by changing the EOB character value. This setup entry is found near the end of the Initialization Setups section, which is Main Menu item 3.
If your application requires a different block-separating EOB character than the standard value of "CR" (13), below is a table where you can look up the value of the character you need. Find the character you want, then look up the Decimal Value (the Dec column). That is the value you will need to use in your AlphaSense setup programming. For example, if all your data blocks ended with a "*", you would used "42" for your EOB character entry. Remember, the end of one block automatically becomes the start of the next block when AlphaSense is evaluating the data stream.
