PowerScan™ PD9330/PBT9300/PM9300
Messages from Host to Reader
The general format to enable the Scanner for a 2 way communication is:
[Scanner_Addr] [Scanner_Addr_delimiter] MESSAGE [CR]
If you have enabled the Scanner Address Stamping or the Scanner
Address Delimiter, you must specify them in every message.
The format for other asynchronous messages is:
[Scanner_Addr] [Scanner_Addr_delimiter] [DC2] MESSAGE [CR]
where DC2 is ASCII 0x12 (^R) character.
• If you have not enabled the Scanner Address Stamping or the Scanner
Address Delimiter, you must not specify them. In this case all messages
will be implicitly addressed to the 'binded' Scanner of the cradle directly
connected to the serial line.
• The Scanner can only receive messages if two-way mode is enabled.
• Messages cannot start with '$+' because they would be interpreted as a
configuration command.
• You can send a message to the Scanner only while it is on. This hap-
pens when it has sent a message to the host and the radio timeout has
not yet expired.
• If you want to control the Scanner's beeper from the host, you will also
probably want to disable the good transmission beep that is emitted
when the code is received from the cradle.
The message field can store plain text and escape sequences.
• Escape sequences are interpreted as commands.
• Plain text is directly printed on the display. If writing beyond the end of
line, the display does not wrap automatically. Extra characters are
ignored. Control characters are not interpreted (i.e. LF, FF, etc.).
