Contact/Tally Mode 3
Ports
Operations
1 through 4
•
Contact ports are controlled externally, using Show Me cables or other button switches.
•
When a specific contact port is shorted (closed), the DTP T SW4 HD 4K switches to the
associated video input.
•
Firmware controls the actions of the tally port.
The tally ports indicate the input currently selected using an LED connection, similar to the front
•
panel LED buttons.
•
When an input button is selected and the contact pin (C) is momentarily shorted, the tally
follows the associated contact port. The associated tally port latches closed, lighting the button
selected. All other tally ports latch open, causing their buttons to not light.
•
Channel and contact port status (open or closed ) for the input selected can be monitored via SIS
unsolicited responses.
5 and 6
•
Contact ports are controlled externally, using button switches.
•
Firmware controls the actions of the tally ports.
•
Tally ports follow the state (opened or closed) of the associated contact port.
For example, port 5 is wired to a Volume Up button. The Volume Up button includes an integrated
•
switch and LED. The Contact pin of port 5 is connected to the switch. The tally pin of port 5 is
connected to the LED.
Port 6 is wired to a Volume Down button. The contact pin 6 is connected to the switch. The tally
pin 6 is connected to the LED.
•
The tally ports light the Volume Up and Volume Down buttons.
When the Volume Up button is pressed, the contact pin (C) is shorted and the associated tally
•
port closes, lighting the selected button.
•
When the Volume Up button is released, the contact pin (C) opens and the associated tally port
opens, turning off the button.
•
Contact status (opened or closed) can be monitored by SIS unsolicited responses sent from the
switcher to the controller via the RS-232 port.
