The Manual Remote connector is a 25-pin D-Sub port used to remotely control
the System 8/10 P switcher by dry contact closures to ground by using an
LUS
Extron hard-wired remote (optional KP-10) or another manufacturer's remote
control device. The connector also has a remote tally lamp capability to light
remote incandescent lamps or LEDs to indicate which input has been selected.
The following specifications are provided to allow the user to match other
devices to these specifications.
Display Power. Pin 11 of the Manual Remote connector is used to switch
projector power. By making a dry momentary contact closure for one second
between pin 11 and ground (pin 25), the system switcher will command the
projector to turn ON. A subsequent one second contact closure will command
the projector to turn OFF.
Display Mute. Pin 24 of the Manual Remote connector is used to mute the
projector video. By making a dry contact closure between pin 24 and ground (pin
25), the system switcher will command the projector video image to mute (blank).
A subsequent momentary contact closure will restore the video image.
Input Channel Selection. Input channel selection is made by making a dry
contact closure between the desired input (pin 1 thru 10) and ground (pin 25).
Continuous dry contact closures can be made to select channels, but such
continuous connections made at the Manual Remote port override all other
means of input selection (i.e., takes precedence over front panel button
selections and RS-232 inputs from a host controller).
Tally outputs (pins 14-23) offer means to poll a status from the System 8/10 to
determine which input is presently selected. The tally outputs also have the
ability to drive a remote front panel with lighted display. Tally outputs are
normally high (5 volts) and drop to a low (0 volts) when selected.
The tally outputs can be used to drive either remote LEDs (right) or remote
incandescent lamps (left). Use one of the following schematics for each of the
tally pins to power a remote display.
The following relays are recommended for use with tally outputs:
