STEREO LINE INPUT
On Tally
Lets the module’s channel ON switch control an on-air light or other
indicator at a remote location. This control function provides a continuous
voltage between Pin 12 (On Tally) and Pin 11 (Digital Ground) whenever
the module is ON. When the module is ON the voltage at Pin 12 is +5VDC.
This on-tally can be used to control an externally powered tally light
that requires a continuous closure to function, or an external tally light (i.e.,
LED) can be powered from the input module by connecting the external
LED to Digital Ground (Pin 11)* and the On Tally port (Pin 12). In either
case, current should not exceed 30 milliamps.
To START and STOP Remote Source Machines Using Module ON/
OFF Switches
EXTERNAL START — Hook up the remote machine’s “start” control
pins to the SLD-600 module’s lower DB-25 connector control pins: for
START A wire to pins 3 and 5; for START B wire to pins 8 and 6.
EXTERNAL STOP — Hook up the remote machine’s “stop” control
pins to the SLD-600 module’s lower DB-25 connector control pins: for
STOP A wire to pins 4 and 5; for STOP B wire to pins 7 and 6.
Note that these are opto isolated outputs. START/STOP COM A (pin
5) and START/STOP COM B (pin 6) are the opto emitters, while the
remaining connections (START A, pin 3; START B, pin 8; STOP A, pin
4; STOP B, pin 7) are the opto collectors. Correct polarity must be
observed in wiring to these connections.
To Control the Module’s OFF Switch LED with an External Source
Machine
READY — Hook up the remote machine’s “ready” control pins to the
SLD-600 module’s lower DB-25 connector control pins: for READY A
wire to pins 1 and 2; for READY B wire to pins 9 and 10. The module’s
Ready ports are looking for a 5VDC signal with pin 2 positive with respect
to pin 1 (READY A) and pin 9 positive with respect to pin 8 (READY B).
As long as the voltage is present in the correct polarity, the OFF switch
LED will be illuminated.
*We recommend a series
resistor between the LED
and Digital Ground when
you are powering the ex-
ternal tally from the con-
sole; a value of 220Ω (1/
4W 5%) is suggested.
