Model 71 Control Console
Configuration
The only configuration choice available on
a Model 71 is its device address. It must
be selected so as not to conflict with the
device address of any other connected
Model 71 or Model 77 Control Console.
The choices are A1, A2, A3, and A4. All
Model 71 units have a default device ad-
dress of A4 while the Model 77’s have a
default device address of A1. This ensures
that, in most cases, no change will have to
be made.
A small button is located on the back of
each Model 71 Control Console, adjacent
to the 9-pin D-sub connector. On any con-
nected Model 71 pressing and holding this
button for two seconds places this spe-
cific unit in its configuration mode; normal
operation of the Model 76D and other
connected Model 71 and Model 77 units
will continue. When a Model 71 enters its
configuration mode its three LEDs will no
longer perform their usual functions. In-
stead the status LED will blink to indicate
that configuration mode is active. The dim
and reference level LEDs will display the
Model 71’s current device address. The
rotary level control is used to select the
desired device address; the LEDs will
respond accordingly. Refer to Figures 7
and 8 for details.
To leave the configuration mode and return
a Model 71 to normal operation requires
one last action; again press and hold its
configure button for two seconds. The
selected device address will be stored in
a nonvolatile memory device that is located
inside this specific Model 71.
Operation
Now that you’ve installed and configured
the system, you’re ready to go. You should
find operation very easy. However, taking
time to study this section of the guide may
prove valuable.
