The current firmware revision number is also displayed on the bottom right-hand corner of the
Sound Devices splash screen at boot up (v2.65+). The 702 firmware version and unit serial numbers
are written to the data chunk of every WAV audio file generated by the 702.
Upgrading Firmware
From time to time Sound Devices may issue revisions (new versions) of firmware for the 702. Firm-
ware is user-upgradeable. To upgrade firmware follow the steps below.
1. Download the firmware file from the Sound Devices web site.
2. Transfer the firmware file (it will be named VERSION _ NUMBER.PRG) to a CompactFlash card in the 702
via FireWire. If there are multiple firmware files on the media, the 702 will indicate the firmware file
listed to apply. To prevent confusion, ensure that there is only one firmware file available on either 702
media.
3. Enter the firmware upgrade menu. You will be prompted to search for the firmware file. If a valid
firmware file is present on the CF card the recorder will prompt if the path is the proper file to use. Press
the Rotary Switch or the tone button to say yes. The 702 will begin firmware upgrade and validation.
Progress is indicated with a bar graph.
4. When the upgrade and verify process is complete, power cycle the 702. On power-up the LCD will turn
solid black and the green LED next to the FireWire port will blink 20 times. When the update sequence
is complete, the 702 will reboot once again.
5. Verify the firmware version using the INFO:SOFTWARE menu.
6. Reset the time-of-day clock, time code generator, and verify any recording parameters.
7. It is best practice to download the latest user guide from the Sound Devices web site, since the changes
to functionality are documented.
Firmware upgrades usually preserve all user menu settings. However, save a snapshot of the settings to
a setup file on the CF. Once a firmware upgrade is complete, restore settings from this file, if necessary.
Some firmware updates may make changes to user setups; verify all user setups after an upgrade.
CL-1 Remote Control and Keyboard Interface
The CL-1 Remote Control and Keyboard Interface is an available hardware accessory to interface
with PS/2 compliant computer keyboards and enable external devices to control the 702. When us-
ing the CL-1, front panel controls and menu selections on the 702 can be mapped to keyboard short-
cuts, allowing for full keyboard control of the recorder. Additionally the CL-1 has contact closures for
programming remote inputs or outputs. These are commonly used for machine control and “remote
rolling” using a mixing console with transport controls.
