procedure
The Automatic sensitivity limit 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 synchronization. When the host starts
the Automatic sensitivity limit procedure remotely, with the command 'j1'given below, then the display will operate
just as if the Automatic sensitivity limit procedure had been started from the front panel keyboard.
Commands the host may transmit:
The host can send any of the following messages :-
1,2,3
',j1'
This starts the automatic sensitivity limit procedure operating for the current product number.
'j?'
This returns the current state of the automatic sensitivity limit procedure (see the 'j'n command
description below).
'j99'
This command is sent when the host wishes to abort the automatic sensitivity limit procedure and return
to normal operation. This is equivalent to pressing the front panel Security key during the automatic
sensitivity limit, and will cause the same action to occur in the metal detector.
Commands the metal detector may transmit
The following command will be transmitted in response to a 'j?' command above, or automatically during the
operation of automatic sensitivity limit.
'j' n

corresponds with the displays on the front panel display as shown below.
