4.2.6. Displaying the Firmware Version
Software operating on the 7707MT-HD has a version number associated with it. This version number can
be indicated to the display. By this means, it can be verified that the module is operating with the most
recent software. To indicate the software version to the display, select the STAT (Status) menu item in
menu level 1, followed by the VER (Software Version) menu item. The following list describes possible
indications for this menu selection:
VER x.x BUILD xxx
4.2.7. Selection the Output Laser Enable Mode
In some applications it is desirable to have the laser output disabled while no input video signal is present
(VID...LOSS condition). Alternatively, it may be preferable to maintain an optical output signal, even with
no input video. The 7707MT-HD supports both modes of operation. To configure the output laser enable
mode, select the CTRL (Control) menu item in menu level 1 followed by the FOUT (Video Output) and
LASR (Laser) menu items.

4.2.8. Selecting AES Sample Rate Conversion
Audio must have a sample rate of 48KHz, and be synchronous to video for embedding. To accommodate
other input audio sample rates, or asynchronous signals, the 7707MT-HD provides sample rate
conversion. Sample rate conversion should be turned on for normal operation, however, Dolby-E audio
uses a proprietary encoding scheme that is not compatible with sample rate conversion; it should be
disabled for Dolby-E. To enable or disable sample rate conversion, select the CTRL (Control) menu item in
menu level 1, followed by the AIN1, AIN2, AIN3, or AIN4 (Audio Inputs 1 through 4) and SRC
(Sample Rate Convert) menu items.
