SPV-1 DIAGRAMS: Upgrading SP1.7 Surround Processors
Older SP1.7 Surround Processors made before November 2002 may require a firmware
upgrade to enable the serial data control link between the SP1.7 and the SPV-1 Video
Switcher. If you experience any difficulties in getting your SPV-1 working properly with
your SP1.7, please contact either your dealer or the factory. SP1.7 firmware revision
41A (or greater) is required.
If you need to install upgraded firmware (Revision
41a or greater) in your SP1.7 Surround Processor,
the SP1.7’s EPROM (Erasable-Programmable Read
Only Memory) chip will have to be replaced. This
chip is located on the SP1.7’s MicroController board
(named “SP1-uC”). The EPROM chip is shown in
black in the diagram above. Detailed installation
instructions will be included with your firmware
upgrade kit. When ordering, please ask for a free
Chip Extractor tool if you don’t already have one.
This simple tool (see illustration to the left) will
make the task of replacing the EPROM simpler and
safer.
