EMULATION MODE
Objective
To generate a facility, which allows the remote control of the metal detector via the existing serial link. The remote
MMI will be a ‘look a like’ of the local key panel, using the same display area as the LCD display (2 x 24 chars) and a
copy of all the keys present on the local key panel.
Principal of operation
Presently, the metal detector software uses the keys of the key panel as input device and the LCD screen as the
output device.
The remote hardware (e.g. PC) will duplicate the I/O devices in a suitable way and as such provide the same facility
to the operator as the local key panel.
Communication between the metal detector and the remote hardware is facilitated via the existing serial link.
Serial command-set supporting emulation mode.
