Adding I/O Modules; Upgrading The Firmware - Prism Sound ADA-8 Operation Manual

Prism Sound ADA-8 Multi-channel A/D D/A Converter

6.2 Adding I/O Modules

WARNING: It is NOT necessary to remove the top cover of the ADA-8 to add
or remove I/O Modules. Removal of the top cover with the mains supply
connected presents a risk of electric shock.
NOTE: Inserting or removing I/O Modules should be carried out with the power
disconnected from the ADA-8. Failure to do this may result in damage to the ADA-8,
the I/O Module or both.
NOTE: To protect from static damage, I/O Modules are supplied in anti-static
packaging. When removed from this packaging, I/O Modules should be handled only
by their metal end-plates. The packaging should be retained, and Modules removed
from the frame should be stored in it.
To decide on the location of a new I/O Module, refer to the diagram of the ADA-8 rear panel in
section 3.2. When viewed from the rear, the analogue I/O (AIO) slots are the larger
castellated panels on the left (AIO1 above, AIO2 below) and the digital I/O (DIO) slots are the
smaller castellated panels on the right (DIO1 above, DIO2 below).
In general, the ADA-8 software regards the analogue slots as interchangeable, and likewise
the digital slots. When loading stored configurations, slot assignments are adjusted to take
into account the number and location of the various I/O Modules. However, it is helpful to
follow the same conventions that apply to factory-fitted Module options, as follows. Where
both Analogue Input and Analogue Output Modules are fitted, the Input Module is fitted to
AIO1 and the Output Module to AIO2. Where both general-purpose and Workstation Digital
I/O Modules are fitted, the Workstation Module is fitted to DIO1 and the general purpose I/O
Module to DIO2. It is not strictly necessary to follow this convention, but to do so eases
comparison with example configurations discussed in the manuals.
To remove an existing Module or blanking plate, first remove the small screws which secure
it. Analogue Modules have nine screws (five at the top of the panel, four at the bottom);
Digital Modules have five screws (three at the top of the panel, two at the bottom). It should
now be possible to gently easy the Module out of its slot – some Modules are more easily
removed by plugging in one or more connectors, and gently pulling the mating connectors
(NOT the cables) to remove the Module.
To fit the new Module, ensure that the edges of the Module locate in the plastic guide rails
within the Module Slot and push the Module gently home. The Module should slide easily to
within about 10mm of its final position, after which firm pressure is needed to seat the Module
in its edge connector. With the Module end-plate resting against the ADA-8 rear panel,
replace the screws. If the Module cannot be easily seated, remove it and try again.
After adding or removing an I/O Module, it is advisable to reload the factory stores (see the
Firmware Reference) since some factory configurations depend on Module fitment.

6.3 Upgrading the firmware

Firmware upgrades are available from your dealer, or can be downloaded from the Prism
Sound website, http://www.prismsound.com. Having downloaded the firmware, it must be
loaded into the ADA-8 by connecting the ADA-8 to your computer with an appropriate cable.
Details of how to do this are included in the readme.txt file included with the new firmware.
