2. Scan a value for data from the “Full ASCII Bar Code Chart” in Appendix C.
The preamble can be from 1 to 25 characters.
3. Scan this bar code:

Example: You want to set the preamble to the letters “BV,” which also represents the
Beep Volume configuration command. Enter the preamble by scanning this bar
code:
Records Per Block
Set Preamble to BV
*$+AD/BBV/B*
$+AD"BV"
If you omit the quotation marks, the reader interprets the command as two
commands: AD to set the preamble to no characters, and BV to change the
beep volume.
Purpose: Defines the maximum number of data records transmitted per block of data.
Usually files are transmitted record by record. This configuration allows you to
transmit multiple records per data block. A block of data is transmitted during
a single transmission, like an individual data record is normally.
Note: The configured option may be overridden when you use certain communications
protocols. Records Per Block will not be overridden when you use User-Defined
protocol.
You must select the communications port and protocol before you set the parameters
that define the protocol. For help, see “Communications Protocol, Configure” earlier in
this chapter.
Default: 1 record transmitted per block
