The following procedure describes how to fit an Easysound module into the
chassis of an Imagestore. Full precautions should be taken to eliminate static
when handling these units, as they contain components that are susceptible to
static damage. It should be noted that there are several screws that may be
hard to reach and connectors that are liable to misalignment if the following
procedure is not followed carefully.
1. Disconnect the mains supply of the host unit before removing its cover.
2. Undo the two screws holding in the PC card (on the rear of the unit), and
carefully extract this card from the ISA bus. Do the same with the
network card, if one has been fitted.
3. Remove the nuts and washers from the rear panel BNC connectors.
4. Examine the rear panel and identify the seven screws that hold the rear
panel assembly in place. These screws are located one on each side of
the chassis, two by the mains inlet, and three on the underside of the unit.
Identify the two screws on the
inside of each D-type connector, which
will also need to be removed. Remove all of these screws and carefully
extract the rear panel. Remove the D-type connectors from this panel,
but retain the screws since they will be required when you reassemble
the unit.
5. Remove the ISA bus from the main PCB by extracting the two screws
from the underside of the unit, and then pulling it free of the main PCB.
Note that the Easysound module fits onto the connectors on the input and
output modules that are, in turn, fitted to the main PCB.
