Message Sending Modes
FS11 messages can either be transmitted automatically at preset intervals,
or polled by commands or polling strings at intervals determined by the
host computer.
Automatic Mode
In the automatic mode the FS11 sensor sends a predefined message at
selected intervals. The automatic and default polled message can be
defined with the SET MESSAGE TYPE command. For available
messages, refer to section Message Formats on page 72. The format of
the SET MESSAGE TYPE command is presented below:
SET MESSAGE TYPE Message_number
The following command selects message 2 as the default automatic
message:
SET MESSAGE TYPE 2
The automatic message interval is selected with command SET
MESSAGE INTERVAL. The message interval is given in seconds. An
interval of zero, which disables the automatic sending, is used when the
messages are polled. The command format is as follows:
SET MESSAGE INTERVAL Message_interval
The following command selects the message to be sent once a minute:
SET MESSAGE INTERVAL 60
The following command disables the automatic sending:
SET MESSAGE INTERVAL 0
The automatic message number is also the default number for the
MESSAGE command and polling.
ACK/NAK Confirmation
In the automatic mode the FS11 system can be configured to require an
acknowledgement for the message reception from the receiver of the
message. By default the ACK/NAK confirmation is disabled. The format
of the SET MESSAGE ACKNAK is the following:
