8.0 E4 System Troubleshooting

8.3 FreeSpace® E4 system Error Log

The FreeSpace E4 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 E4 system hardware version numbers and records all alarms and their causes as shown in the following example.

• Host controller – The host controller monitors and controls the

operation of the E4 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 70.

• 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 70.

• 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 70. 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 70.

• 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

8.3.2 Hardware configuration

The E4 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 E4 hardware at the time of manufacture.

These version numbers do not pertain to the FreeSpace 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 E4 hardware to determine if it is capable of properly perform- ing audio processing and amplification. During the POST test, six major components of the hardware are tested.

the POST test results. If a 12C, or code failure occurs, contact

Bose Customer Service. See “Customer support” on page 70.

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, “Power-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 70.

Programmer’s Note: The USB port is not currently used for communication with the E4. If a USB failure occurs, the E4 will still function normally for audio pro- cessing and amplification.
