Unit Identification Code
The next two front panel thumbwheel switches
(Channels 3 and 4) are used to program the Unit
Identification Code. In a single unit system (Mode 3),
changes to these values are irrelevant. In multiple
unit remote configurations, this value can be any
number from 01 to 99, but care must be taken to
insure that all units have a unique ID code.
Programming
Programming the configuration information into
internal EEPROM is accomplished by first setting the
front panel thumbwheel switches (Channel 1-4) to the
desired setting. The unit is then powered up while
depressing the front panel LOAD pushbutton. Upon
power up, the internal microprocessor detects the
depression of the LOAD switch , and then programs
the internal EEPROM memory with the selected
values. The unit will flash the front panel SET LED for
a few seconds to indicate that it is programming the
system EEPROM, and will then enter the operating
mode. The unit will now enter the appropriate
operating mode whenever it is powered up. The unit
can be reprogrammed any time the user desires, and
the internal EEPROM is rated for an excess of 10,000
write operations.
Operation
The following paragraphs detail the operating
procedures for each of the four operating modes that
can be programmed into the AS8x8 Audio Crosspoint
Switch.
Mode 1 (Scanned Manual Mode)
When operated in this mode, the user sets the front
