ISA One Instructions
Removing the Top Cover
Remove the 10 crosshead screws fixing the top cover to the top and sides
of the ISA One 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 three 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 three of the four supplied
crosshead screws and the three support ledges within the unit, as
shown below.
Fitting the Card
Place the card into the unit with the cable pointing towards socket J14A.
Rest the card on the ledges so that the three holes on the card line up
with the three holes on the support ledges. Screw the card into place
using three of the four crosshead screws and the three 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 One labelled J14A. The
connector should be pressed firmly down in place, until the two latches
have locked, 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 10 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 One Unit with the ADC fitted
The ISA One 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 One 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 One 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.
Notes
When syncing to an external clock, the sampling frequency should be the
same on all devices in the digital chain. If you experience any difficulties
installing the digital option, please contact Focusrite technical support at
