E-4 system Error Log
The FreeSpace E-4 system Error Log is displayed when the
Installer
™ software is in the Service Hardware mode.
8.3.1 Contents of the Error Log
The Error Log displays E-4 system hardware version numbers
and records all alarms and their causes as shown in the following
example.
8.3.2 Hardware configuration
The E-4 system hardware version numbers appear at the top of
the Error Log listing. These are the version numbers of the soft-
ware installed in the E-4 hardware at the time of manufacture.
These version numbers do not pertain to the FreeSpace system
Installer
™ software installed on your PC.
8.3.3 Power-on self-test results
The power-on-self test (POST) results are only displayed when an
error has occurred. The POST test checks the basic operation of
the E-4 hardware to determine if it is capable of properly per-
forming audio processing and amplification. During the POST
test, six major components of the hardware are tested.
•
Host controller
– The host controller monitors and controls the
operation of the E-4 hardware. A host controller failure will
cause the message, “Power-on self-test incomplete” to appear
in the host controller test section. The failure type for a host
controller is an SRAM address failure. If this occurs, contact
Bose Customer Service. See “Customer support” on page 69.
•
Flash memory test
– The flash memory contains the configu-
ration, design file, and system event schedule. A flash failure
will cause the message, “Power-on sel-test incomplete” to
appear in the host controller flash test section. If this occurs,
contact Bose Customer Service. See “Customer support” on
page 69.
•
Peripheral controller
– The peripheral controller monitors con-
tact closures, front panel connections and user interface con-
nections for incoming event messages. Any failures in these
areas will cause the message, “Power-on self-test incomplete”
to appear in the peripheral controller flash test section. If a 12C,
or code failure occurs, contact Bose Customer Service. See
“Customer support” on page 69. If a user interface failure
occurs, check the user interface wiring for shorts.
•
DSP test
– The DSP performs all signal processing and routing
functions. If a DSP error occurs, contact Bose Customer Ser-
vice. See “Customer support” on page 69.
•
Upper and lower amplifier test
– The upper and lower ampli-
fier test determines if the amplifiers are operating properly. An
amplifier failure will cause the message, “Power-on self-test
incomplete” to appear in the upper or lower amplifier section of
the POST test results. If a 12C, or code failure occurs, contact
Bose Customer Service. See “Customer support” on page 69.
Additional details on the exact cause of an amplifier failure can
be found in the amplifier section of the Error Log.
•
Front panel board test
– The front panel board test deter-
mines if the USB port is working properly. A USB failure will
cause the message, “Powe-on self-test incomplete” to appear
in this section of the POST results. If a USB failure occurs, con-
tact Bose Customer Service. See “Customer support” on
page 69.
Programmer’s Note:
The USB port is not currently
used for communication with the E-4. If a USB failure
occurs, the E-4 will still function normally for audio pro-
cessing and amplification.
