6. Set the communication parameters (Baud Rate, Data Bits, Stop Bit, and Parity Bit) to
values recommended by the manufacturer of the device.
7. Ignore the Buffer Size for now. This value is dealt with using procedure
Adding an Event
Rule for a Data-recording Device, below.
8. To add a data-recording rule(s), see the next procedure.
Fig. 8–10. Some Devices can Be Searched for Data such as “No Sale”.
Adding an Event Rule for a Data-recording Device
1. While or after adding a data-recording, serial device, as explained in the procedure
Adding a Customer Device That Sends Data to a Unit, above, click in the Event Name
box and type a name, for ex. “No Sale”.
2. In the Event Rule box, type:
• A code obtained from the manufacturer of the device. For example, a no sale
message from a device is coded as one or more numbers, or text. See the
documentation for the device.
– or–
• A regular expression of your choice; see the
Search Rule and Regular
Expressions: Reference, next.
3. Click Add.
4. Compare the value in the Buffer Size box to the length of rules typed in step 2. You have
the option of changing the number of bytes in the buffer so that it is greater than or equal
to the longest rule added in step 2 of this procedure. Consider if any rules use wildcards
(see table
8–6); you may need to use a bigger buffer. The default value of 250 bytes
should be adequate for most organizations.
5. You have the option of adding more events, as many as 512 different events or regular
expressions can be processed for each data-recording device.
