Peripheral devices control the module through
the Reset and Ready logic inputs. In the example
on pages 2-52 and 2-53, only the Ready function
is used. The Ready function performs an audio
reset, which turns off the module without gener-
ating a Stop Command Pulse. In addition, it also
controls the Off lamp illumination.
In the example on pages 2-54 and 2-55,
Reset (+) and Ready (+) connect to Logic Supply
+5VDC on the module. The Ready (-) command
and the Reset (-) command are pulled low by the
active low logic relay outputs on the peripheral
device, which all tie to the module’s Logic Ground
(pin 1).
For peripheral devices that require a steady on
signal, the Start Command Sustained output can
be used.
Additional Logic Connections
There are additional logic connections on the
Meter Switcher module, Control Room module,
and optional Studio module
Three 3-pin connectors on the Meter Switcher
module interface remote timers so they can be
reset by the console timer reset logic. The Meter
Switcher module also has factory-installed cabling
for the timer, the talkback mic, and the digital
level meters. For more information on the Meter
Switcher module’s logic connections and settings,
see pages 2-28 to 2-30.
A 14-pin connector on the Control Room mod-
ule carries the logic interface for the Control Room
warning light, remote mute and dim inputs, and
the mute, dim and talkback tallies. The 8-pin Cue
Cntl connector on the Control Room module has
the External Cue logic interface. For more infor-
mation on the Control Room module’s logic con-
nections and settings, see pages 2-32 to 2-36.
The optional Studio module includes a 14-pin
connector to control the studio’s logic, including
warning lights, mutes, and dims. The Studio mod-
ule also has a 16-pin connector for the audio and
logic for an external site’s talkback audio and con-
trol. For more information on the Studio module’s
logic connections and settings, see pages 2-38 to
2-45.
