STEREO LINE INPUT
when hooked up to the control pins with the correct polarity, will activate
the module’s channel ON and OFF switches.
REMOTE ON — Activates the module’s channel ON switch. Momen-
tary connect the plus side of a 5 volt signal to Pin 9 and the minus side of
the same 5 volt signal to Pin 11 of AMP D to latch the module ON when
input A is selected. Use pins 9 (+) and 11 (-) of AMP C to latch the module
ON when input B is selected.
REMOTE OFF — Activates the module’s channel OFF switch.
Momentary connect the plus side of a 5 volt signal to Pin 5 and the minus
side of the same 5 volt signal to Pin 7 of AMP D to latch the module OFF
when input A is selected. Use pins 3 (+) and 1 (-) of AMP D to latch the
module ON when input B is selected.
See also “Remote ON/OFF – Constant vs. Pulse” on page 3-4.
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
+5 volts at Pin 2 (C) (On Tally) relative to Pin 4 (C) (Digital Ground)
whenever the module’s channel ON switch is activated.
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-5 module’s AMP C and D connectors control pins: for A
START wire to Pin 8 (D) and Pin 4 (D); for B START use Pin 10 (C) and
Pin 2 (D).
EXTERNAL STOP — Hook up the remote machine’s “stop” control
pins to the SLD-5 module’s AMP C and D connectors control pins: for A
STOP wire to Pin 6 (D) and Pin 4 (D); for B STOP use Pin 12 (C) and Pin
2 (D).
Note that these are opto isolated outputs. START/STOP COM A Pin
4 (D) and START/STOP COM B Pin 2 (D) are opto emitters, while the
remaining connections (START A, Pin 8 (D); START B, Pin 10 (C);
STOP A, Pin 6 (D); STOP B, Pin 12 (C) are opto collectors. Correct
polarity must be observed in wiring to these connections.
See also “Remote START/STOP – Normal vs. EFS” on page 3-5.
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-5 module’s AMP C and D connectors control pins: for A READY
provide a 5 volt signal to Pin 10 (D), positive relative to Pin 12 (D); for B
READY provide a 5 volt signal to Pin 8 (C), positive relative to Pin 6 (C).
As long as the voltage is maintained, the module’s OFF LED will be
illuminated.
A diagram showing typical connections is shown on the next page.
