4.2.15. Selecting the Serial Data Fail Safe Bias
RS-485 applications sometimes require a failsafe bias at the serial data interface, to ensure a known
signal state while communications are in an idle state. The 7707MTA-HD provides a configurable failsafe
bias to accommodate such requirements. To configure the failsafe bias, select the
CTRL
(Control) menu
item in menu level 1, followed by the
SER
(Serial Data), followed by the
BIAS
(Failsafe Bias).

4.2.16. Selecting the Audio Embedding Groups
This user menu item provides configuration of the embedded audio groups. Incoming embedded audio
groups are cleaned from the video, and should be re-assigned as desired using this menu option. To
select the audio embedding groups select the
CTRL
(Control) menu item in menu level 1, followed by the
EMBD
(Audio Embedding),
AUD
(Audio), and
GRP1, GRP2, GRP3
or
GRP4
menu items. Then, select
from
CH1
or
CH2
(channel 1 or 2) for that audio group.
