are rejected. Wait for the procedure to complete—it will take only a few
minutes. Progress bars show upload progress.
4. Click Commit Uploaded Firmware when prompted after the upload is
finished. Progress bars show progress as the file is written to flash memory.
5. Click Restart FS2 with New Firmware to restart the FS2. This will take the
FS2 offline for a minute or two. During the restart, progress is shown in the
connection area in the upper right corner of the FS2 Status screen. After
restart, the FS2 will be running the new software.
6. Once these steps are complete, the FS2 will be running the software, and
the Software Version on the Status screen shows the new version number.
Check that the new software is running by bringing up the FS2 web page
again; the software version is displayed at the top of all FS2 web screens. If
the FS2 did not update successfully, run through the update steps again.
NOTE: The configuration of the FS2 prior to the upgrade is preserved. The unit returns to
service exactly as it was before the upgrade.
If there is a power outage or glitch during the software download, the FS2 will
boot the older software version and you can restart the upgrade process. This
happens because the FS2 has been designed with a safety feature where an
internal “safe” copy of the previous software is retained in the event the updating
process fails.
System Cabling
System Video/Audio Cable Connections
When installing your system, you’ll make video and audio input/output
connections. These connectors are explained individually in Chapter 2.
GPI Connections
The FS2 has four GPI inputs and four GPI outputs. The GPI inputs and outputs
are electrically isolated from the power and ground on the FS2 frame. Electrical
isolation is provided for up to four pieces of external equipment.
See
for information on how to wire the GPI connector
to work with external devices that you want to use to control the FS2 or that you
want the FS2 to control.
FS2 Audio Level Choices—Pro or Consumer, US or EBU
Since the FS2 handles both digital and analog audio and can convert between the
two, it provides analog and digital audio level settings in the front panel menus
and the remote web browser. Standard practice typically sets the maximum
audio level approximately 20 db above the operating (alignment) level, allowing
enough headroom to handle peaks without clipping. Because different countries
and equipment types use different operating and maximum levels, the FS2 has
several audio level settings. These settings allow you to set the relationship
between the analog and digital audio levels to accommodate the equipment and
audio operating standards you use.
The FS2 offers four settings shown in the following table. The analog audio levels
listed in the table are defined in reference to 0 dBFS (where FS = full scale), which
is the maximum level that can be represented digitally. Note that the test method
for these levels uses a 1kHz sine wave.
