Message Formatting
Message Formatting is available for PM9300 models only.
For this feature to be operational, the scanner must be set to
I
gnore Host Commands (see
page 23
).
A message from the Host to the base must follow these rules:
If Address stamping options or addr
ess delimiter are enabled on the
base, the Host replay must have address field and delimiter too. Other-
wise the message will be ig
nored. Address delimiter is present only
when address stamping is enabled.
Address stamping is necessary to co
rrectly route the message to the
PM9300, especially when more than one handheld is linked to the same
base. Address stamping could be disabled if the system is in point to
point configuration. If address stamping is not enabled, the messages
are addressed to the first handheld linked to the base.
The maximum character length for messages is 48.
Messages end with “CR” 0x0D ASCII character. The CR character cannot
be contained in
the middle.
Messages cannot start with '$' or # because these are reserved for Ser-
vice mode command
Base station can receive host message only if Host Commands Obey/
Ig
nore is set to Ignore.
Message could be sent to the handheld in response to a Label when
“Transmit
mode” require Ack from Host (see transmit mode parameter)
or at any time. When messages are sent not in response to a label must
start with DC2 0x12 ASCII character and could be sent in any transmit
mode setting.
Message could be sent to all handhelds linked to the base by using a
Mu
lticast message:
“00 00 00 00 2A AA”
In order to receive a message, handhelds must not be in sleep state.
The format of the ACK from Host message (used for transmission mode 02) is:
[Scanner_Addr] [Scanner_Addr_delimiter] MESSAGE <CR>
The format of a generic message From Host to HH is:
[Scanner_Addr] [Scanner_Addr_delimiter] DC2 MESSAGE <CR>
where DC2 is ASCII 0x12 (^R) character.
[Items in square brackets are optional.]
If you want to control the Scanner's beeper from the host, you will also
probably want to disable t
he good transmission beep that is emitted
when the code is received from the cradle. (See "Wireless Beeper Fea-
tures" on page 198).
The message field can store plain text and es
cape sequences.
Escape sequences are interpr
eted as commands.
