Overview
The CTC-1402 is a 4K 6x Multi-format Inputs Extender Switch with USB extension and includes a scaler for CTC-1402. The
transmitter and receiver kit offers six video inputs shared between both devices for HDMI, Display Port, VGA plus analog
audio in and USB-C video signals. To simplify conference room device management, the kit provides four USB type B
connectors for host Computers. Six built-in USB hubs, three on the transmitter and three on the receiver, allow for the use of

1. Connect input sources
Connect HDMI/VGA/DP/USB-C sources to HDMI IN/VGA IN/DP IN/USB-C IN ports of TX or RX.
Note: The CTC-1402 allows users to connect BYOD wireless systems to HDMI IN as a source.
Note: For USB-C Video sources the use of a USB 3.0 cable with minimum transfer data rate of 5 Gbps is required.
Connect the BYOD system HDMI display to the CTC-1402 HDMI IN port.
2.
Connect display
Securely connect display devices such as a TV to HDMI OUT ports of the RX, ensuring both source and display devices
are compatible and correctly configured to accept the signal.
3.
Connect TX and RX
Connect a good quality, well-terminated shielded Cat 6A/7 cable with an RJ45 connector wired to the 568B standard
at both ends from the HDBT OUT ports of TX to the HDBT IN ports of the RX.
Note: For more information regarding cabling, refer to the Cable Specification section.
4.
Connect USB HOST devices.
Connect a PC to USB HOST ports with USB cables.
5.
Connect USB devices to the USB DEVICE ports of TX and RX.
Note: For more information, refer to “USB Control” section. USB-C is automatically recognized when the USB-C input
is selected. The PC can be connected to other US.
6.
Connections additional control options:
1)
IR
Plug the IR emitter into the IR OUT port of RX and plug the IR broadband receiver into the IR IN port of TX. Users can
control the display, such as a projector, which is located at RX side with its remote.
2)
LAN Control (Telnet/Web UI)
Connect the LAN ports to an Ethernet device such as an Ethernet switch.
3)
RS232-P
Connect an RS232-enabled device to the RS232-P port of TX (or RX) and connect an RS232-enabled device to the
RS232-P port of RX (or TX) for RS232 pass through.
4)
RS232-C
Connect an RS232-enabled client device (e.g. projector) to the RS232-C port and connect the projector screen to
RELAY port (1-2). Send commands to RS232-C via NetLinx Studio.
7.
Connect power to the TX and RX. Power on all input sources and displays.

Input Source Switching
The CTC-1402 Kit supports Auto and Manual button switching between the HDBT (HDMI, VGA) and HDMI inputs.
Auto Switching
Press AUTO button. The Auto Switching function will be enabled immediately.
1.
If more than one input ports have active signal, the priority order is VGA 1 > DP IN 2 > HDMI IN 3 > USB-C 4 > RX
HDMI IN 1 > RX HDMI IN 2;
2.
New insert: LIFO (Last In-First Out);
3.
New pull out: When the selected source is pulled out, the unit switches to the last selected port. If there is no active
signal, the unit switches to the port with the highest priority;
4.
If all input ports have no active signal, the RX HDMI IN 1 is set to active.
Note:
• The Auto Switching function is enabled by default once all devices are powered on.
• Auto Switching can be set to Enabled or Disabled through NetLinx Studio and the front panel button.
• Power-off protection: When Auto Switching or Manual Switching are selected before powering off, the device will
remain in
the same mode after powering back on. When Auto Switching is selected before powering off, and the
previously selected port has active signal after powering the device back on, the port will remain selected. If the port
is not active, and more than one input ports have active signal, Auto Switching will follow priority order.
Manual Switching
Press the AUTO Button (ensure AUTO LED is off) or the specific input button (in red frames above) to enable Manual
Switching. In Manual Switching mode:
1.
When the input port with no source is selected, CTC-1402 will output no signal;
2.
If the Power is cycled, on the CTC-1402, the Manual Switching function will remain enabled.
Note:
• Manual Switching is also available when Auto Switching is on, but will only apply to active input sources.
• Manual Switching will remain available when Auto Switching is off, and can switch among inactive input ports.
