Connect Wiring (Fig.1)
The Din Box Display housing (8) has 4 push-out panels (10), two in the top face and two in the rear face of housing.
Two of these panels must be knocked out, to allow cable connectors to be fed through the housing and into the display
board (12).
There are two rubber grommets located inside the rear face of display housing.
Remove both grommets then, using a scalpel or sharp knife, cut a slit of approximately 2cm. in each grommet.
Fit grommets (9) over display cable and keyswitch cable connectors respectively, then slide grommets along cables,
approximately 10cm. from the connectors.
Pass display lead connector through left hand aperture in housing, looking at display from front, then plug into display
connector (13) in display board (12). See Fig 1B for Tuscan controller board CN8 connection.
Pass Keyswitch connector through right hand aperture in housing, looking at display from front, then plug into 6 pin
Keyswitch connector (5) in keyswitch board (4). See Fig 1A for Tuscan controller board CN9 connection.
Fit grommets into their respective apertures, ensuring that they are correctly seated.
Install Display in Housing (Fig. 3)
When you install the display unit in the housing you
must take up the slack in both cables.
Holding assembly in both hands, with both thumbs
at top of front face, press display into the housing.
The display will snap into position.
Press both lower corners of display unit front face, to
ensure display is seated correctly in housing.
Replace Door Flap (Fig. 2)
