4.2.8. Displaying the Firmware Version
Software operating on the 7707MTA-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.
VER x.x BUILD xxx
Software version. Character string scrolls across four digit display.
4.2.9. Selecting the Laser Output Mode on LOS
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. Note that the Output Mode on LOS selection (section 4.2.10) determines the output signal
content. The 7707MTA-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
(Fiber Output) and
LASR
(Laser) menu items.

4.2.10. Selecting the Video Output Mode on LOS
In order to maintain audio transport during input video loss, a generated output video signal may be
enabled during this condition. A black or gray active picture may be selected. Alternately, to force a
downstream signal loss during this condition, output generation may be disabled. Note that the Laser
Enable Mode supersedes this selection. To configure the output mode on LOS, select the
CTRL
(Control)
menu item in menu level 1 followed by the
FOUT
(Fiber Output) and
GEN
(Generation) menu items.
