Ch / Frequency Menu; Encoder Menu; Audio 1 Menu; Audio 2 Menu - Gigawave D-Cam Clip-On Operator's Manual

3.2.3 Ch / Frequency Menu

This menu is used to select one of the sixteen pre-channels (CH1 – Ch16) or 'manual'
frequency. The 'Man' setting allows control of the transmit frequency in 0.5MHz steps
within preset limits. These limits can be confirmed using the Remote PC Interface See 6.2
for details.
The Enter button allows the ? ? buttons to select the required digit, the ? ? buttons then
select the required value. The Enter button then stores the value and returns to the Main
menu.

3.2.4 Encoder Menu

Using the ? ? buttons, this menu is used to select the require d MPEG encoder operating
parameters. These are held in eight non-volatile memories (0 – 7). The display will also
indicate the modulation mode (QPSK, 16QAM, 64QAM) and the transport stream data
rate.
A separate sheet is supplied defining the settings programmed into the D-Cam Clip-On
unit.

3.2.5 Audio 1 Menu

The Audio menus are split into two levels: Select Input and Set Level.
The ? ? buttons and Enter are used to select the required audio sub menu.
The audio input can be set for either Line or Mic input; selecting Mic gives a fixed +20dB
gain.
There is also a level adjustment providing a +/- 20dB in 0.5dB steps. This level adjustment
is intended to cater for variations in camera audio output levels, it is NOT intended to use
these adjustments to set microphone sound level. It is assumed that the mic pre -amp and
limiter within the camera is used for this purpose.

3.2.6 Audio 2 Menu

As 3.2.5 above but for setting the Audio 2 input and level.

3.2.7 Status Menu

The status menu is used to confirm the condition of the D-Cam Clip-On. If the Status LED
is red indicating a fault or warning, the Status menu will indicate the nature of the problem.
The ? ? buttons are used to scroll through the various functions:
