IR Emitter Control
The IR Sensor on the front panel may also accept signals from a Compass Control
®
Master
Controller or from a 3rd party control system. When using a Master Controller or 3rd party
control system, the IR Emitter must be mounted over the IR Sensor on the front of the
KD-Pro2x1/KD-Pro4x1 unit. The other end of the cable is connected to the Multi-function I/O
port on the Master Controller or the IR Extender/IR Connecting Block of the 3rd party control
system.
Auto Sensing Slide Switch
The KD-Pro2x1/KD-Pro4x1 unit may auto sense for a present HDMI signal to switch input.
There are two positions for this switch.
Auto Sensing ON
»
Unit is forced to auto sense for a present HDMI signal and will switch to the
corresponding input/source that is detected
»
The IR Remote , RS-232, or TCP/IP commands cannot change the state of the Auto
Sense mode
Auto Sensing OFF
»
Unit is in normal mode and regular switching functionality will occur
»
The IR Remote, RS-232, or TCP/IP commands may enable or disable the Auto Sense
mode
Trigger In, Serial IR, RS-232, and TCP/IP Control
The KD-Pro2x1/KD-Pro4x1 features a 6-Pin Terminal Block for Trigger In, IR, and RS-232
Control. Signals may be received from these connections as well as the Ethernet Jack for
TCP/IP Control. Serial commands may be found in the “Communications Protocol” section.
For Trigger In, a push button may be used that would externally trigger the front push button.
The external push button would be wired to Pins 1 and 3 on the 6-Pin Terminal Block. Trigger
In is Pin 1; Ground is Pin 3. The external push button would short these two pins and would
operate the unit as the front push button (Input Select) would.
For Serial IR, connect a mono cable to the Multi-function I/O port on the Master Controller or
the IR Extender/IR Connecting Block of the 3rd party control system. The other end would
then connect to Pins 2 and 3 on the 6-Pin Terminal Block. IR In is Pin 2; Ground is Pin 3.
For Serial RS-232, connect a stereo cable to the Multi-function I/O port on the Compass
Control Master Controller or the RS-232 port of the 3rd party control system. The other end
would then connect to Pins 4, 5, 6 on the 6-Pin Terminal Block. Tx Data is Pin 4; Rx Data is
Pin 6; Ground is Pin 5.
For TCP/IP control, connect an Ethernet cable from the KD-Pro2x1/KD-Pro4x1 to a network
router or connect a crossover cable from the KD-Pro2x1/KD-Pro4x1 directly to a PC.
