EEPROM by keying in the quote (") character. Command mode is required for access to
this command.
Note: To test if this command is active when the unit is not flowing data, send a carriage
return (or any other non-command character to the sensor, and observe if there is any
output.
7. A "+" command will suppress or restore the transmission of data. This command will
toggle the data transmission (On to Off; Off to On). Command mode is required for access
to this command.
Note: It is possible for both the ":" and the "+" commands to be active at the same time.
The "+" command determines whether the sensor is allowed to transmit data. So if this were
the case, the ":" command must also be turned off to allow the free flow of data.
8. An "*" command will suppress or restore the initialization message in the Decimal ASCII
mode. This command will toggle the transmitting of the text header during initialization
(On to Off; Off to On). This change is made non-volatile in the unit on EEPROM by keying
in the quote (") character. Command mode is required for access to this command.
9. An "&" command brings up a menu which allows any of several parameters to be set.
These are system time constants, selection of data channels for serial output, and baud rates.
This change is made non-volatile in the unit on EEPROM by keying in the quote (")
character. Command mode is required for access to this command.
The commands "~", "@", "#", "$", '(", ")", "{", "}", "|", "<", ">" and "?" are used by the Watson
factory to calibrate the unit and should be used only with the assistance of the factory. If an
undesired function is called, a "Q", and sometimes Escape or a Delete will interrupt the command
and return to operation with the least disturbance to the system. All other unspecified characters
such as carriage return, line feed and space are ignored by the system.
If there are problems with the system "hanging up" during the binary output mode, check for
crosstalk between the serial transmit and receive line in your installation. In addition, check to see
that the communications program used is not sending an echo. This will not happen in the decimal
or hexadecimal modes because command characters recognized by the system are not produced in
those modes.
