Command Identifier - ‘b’

Automatic setup Procedure

The Automatic setup procedure can be started remotely by the host or from the front panel keypad, in either case the
front panel display and the communications commands would be in synchronisation. If the host starts the Automatic
setup procedure remotely, with the commands given below, then the display will operate just as if the Automatic
setup procedure had been started from the front panel keyboard.

Commands the host can transmit

The host  can send any of the following messages :-

‘b1’ 

1

 

, 2

This starts the automatic setup procedure operating for the current product number.

‘b?’

This returns the current state of the automatic setup procedure (see the ‘b’n command description
below).

‘b14’

This command should be sent when the detector is in a state where a YES or NO decision is made.
Transmitting this command is equivalent to selecting YES on the keypanel.

‘b90’

This command should be sent when the detector is in a state where a YES or NO decision is made.
Transmitting this command is equivalent to selecting NO on the keypanel.

‘b99’

This command is sent when the host wishes to abort the automatic setup procedure and return to
normal operation.   This is equivalent to pressing the front panel key ‘PROG/EXIT’ during the automatic
setup, and will cause the same action to occur in the metal detector.

For a description of the states see the ‘Auto Setup Flowchart

Commands the metal detector may transmit

The following command will be transmitted in response to a ‘b?’ command above, or automatically during the
operation of automatic setup.

‘b’n

n is a number indicating the state of the automatic setup’s progress, the number, n, corresponds with
the displays normally on the front panel display as shown on the next page.

Note the special case n = 0 means that automatic setup is not running.

Notes

1

   During an Auto Setup procedure, initiated by the host, the transmission of the bargraph and detection

     messages (‘A’n and ‘R’n), will be suppressed.   After completing the automatic setup, these messages will be
     resumed if they had been enabled prior to entering the automatic setup.

2

   The command ‘b1’ cannot be sent if the current product number is 0.   Automatic setup is not available on

    

 product number 0
