Module Configuration
When installing the 8936 module, there is an eight position DIP switch (S1)
that must be checked and/or set.
DIP switch S1 determines if automatic or manual data rate selection mode
is desired. It also determines if the EQ warning alarm and video present
alarm will be indicated on the health alarm line. Refer to Figure 4 for the
location of S1 and the possible settings.
Figure 4. S1 Settings

signal present LEDs. If there is not a signal present, no LEDs will illumi-
nate. Refer to

present LEDs will only illuminate if that particular signal is present. Refer
