REMOTE CONTROL OPERATION
The IN3504 / IN3506 RGBS switchers have a REMOTE CONTROL port which allows these units to be
remotely controlled. Channels can be selected through the remote port by providing contact closures
between the appropriate pins. The port also includes a +5V power supply and tally outputs. Several
contact closure type control devices are available including:
IN3590 - An optional hard wired remote designed to work with IN3500 Series switchers.
IN6901 / IN6902 RS232 to Contact Closure Converters - allow IN3500 Series switchers and
other INLINE devices with contact closure control ports to be controlled by RS232 sources such
as control systems and computer serial ports.
Control System - many control systems are capable of providing contact closures.
Control Parameters
In order to select a channel, the channel select pin (pins 1 - 6) must be connected to Common (pin 7 or 8).
The contact closures may be momentary or continuous (latching).
Example: To switch to Input Channel #4, apply a contact closure between Pin 4 and Pin 7.
If two channels are selected simultaneously, the output of the switcher is blanked (no output is selected).
In order to maintain blanking these two closures must be continuous.
Tally Output
The REMOTE CONTROL port also provides tally outputs (pins 10 - 15) which may be used to trigger
other devices, provide feedback to a control system, or light indicator lights on a custom remote control
panel. When a channel is selected, either from the front panel or through the REMOTE CONTROL port,
the Tally Output for that channel is switched on. The Tally Output can switch voltages of up to 50 volts
and current up to 1.5 amps.
