Message Formatting
Message Formatting
NOTE
Message Formatting is only available for the QuickScan™ Wireless model.
A message from the Host to the base must follow these rules:
• If Address stamping options or address delimiter are enabled on the base, the Host replay
must have address field and delimiter too. Otherwise the message will be ignored. Address
delimiter is present only when address stamping is enabled.
• Address stamping is necessary to correctly route the message to the QuickScan I, espe-
cially 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 Service mode command
• Base station can receive host message only if Host Commands Obey/Ignore is set to
Ignore.
• Message could be sent to the HH 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 HH linked to base by using a Multicast 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 the good transmission beep that is emitted when the code is received from the
cradle. (See "
Wireless Beeper Features" on page 212
).
The message field can store plain text and escape sequences.
• Escape sequences are interpreted as commands.
