ISA 430 MKII Instructions
Removing the Top Cover
Remove the 11 crosshead screws fixing the top cover to the top and sides
of the ISA 430 MKII unit.
Removing the Digital Option Cover on the Rear Panel
The rear panel digital connector area is accessed by removing the rear
cover plate above the ‘DIGITAL OUTPUT’ labelling. The plate is removed by
removing the two crosshead screws shown below. Retain these screws for
securing the digital card in place later.
Installing the Digital Option
The digital card is mounted in place using the four supplied crosshead
screws and the two support brackets within the unit, as shown below.
Fitting the Card
Place the card into the unit with the cable pointing towards socket J42.
Rest the card on the brackets so that the four holes on the card line up
with the four holes on the bracket. Screw the card into place using the
four crosshead screws and the two screws retained from the rear digital
option cover.
Once the card has been secured into place, the digital card ribbon cable
can be connected to the socket on the ISA 430 MKII labelled J42. The
connector should be pressed firmly down in place to ensure a good
contact.
N.B. The cable has an orientation tab that should align with the
orientation notch in the socket. If this is not correctly aligned, the cable
will not fit correctly –
do not force it!
Replacing the Top Cover
The top cover should now be replaced, using the 11 crosshead screws to
secure firmly to the chassis.
The installation is now complete and the unit can be reconnected to the
AC power.
Initialising the ISA 430 MKII Unit with the ADC fitted
The ISA 430 MKII recognises the installation of the digital card after you
have carried out the following step:
• Press and hold down any switch on the front of ISA 430 MKII whilst
powering up the unit. Once the front panel is illuminated, release the
switch.
The digital card will now be active. This is a one-time action. Once
initialised, the ISA 430 MKII will recognise the presence of the ADC each
time the unit is powered up.
Please refer to the full User Guide for digital card operation.
