Product Introduction

Thanks for choosing the PT-C-HDCEC 18G In-line HDMI Controller, which is designed for automatic system control and HDMI signal extension in small meeting rooms and huddle spaces. The controller supports a variety of system trigger methods, via IR signal input or video signal detection (5V "Hot-Plug-Detect" or "TMDS sensing"). It automatically triggers CEC commands as well as pre-loaded RS232 and IR commands to turn on or off devices as well as relay control to lower and raise projection screens. It supports video resolutions up to 4K@60Hz 4:4:4 with HDR 10 and Dolby Vision support and is capable of 4K to 1080p down-scaling, for compatibility with 1080p display devices. Besides passing EDID information from the display, there are multiple built-in EDID settings that can be selected using the 4-pin DIP switch on the front panel. In addition, the controller supports CEC pass-through, RS232 control, IR learning and relay control.

Features

• Supports up to 4K@60Hz, 4:4:4 with HDR10 and Dolby Vision support, HDCP 2.2 compliant.

System Connection

Usage Precaution

• Make sure all components and accessories are included before installation.
• System should be installed in a clean environment with proper temperature and humidity.
• All of the power switches, plugs, sockets, and power cords should be insulated and safe.
• All devices should be connected before power on.

System Diagram

The following diagram illustrates typical input and output connections that can be utilized with this controller:

DIP Switch Operation

EDID Management

The Extended Display Identification Data (EDID) is used by the source device to match its video resolution with the connected display. By default, the source device obtains its EDID from the first connected display. Meanwhile, when a display with different capabilities is connected to the controller, the DIP switch on the front panel can be used to set the EDID to a fixed value to ensure the compatibility in video resolution.

The switch represents “0” when in the lower (OFF) position, and it represents “1” when putting the switch in the upper (ON) position.
Switch 1~3 are used for setting the EDID. The DIP switch status indicator and its corresponding setting are shown on the back of the product.

2CH: Supports LPCM 2CH.
Multi-CH: Supports LPCM 8CH, Dolby TrueHD, DTS-HD, Dolby Digital 5.1, DTS 5.1, Dolby Digital Plus.

User-defined EDID Setting

Except directly invoking the built-in EDID, the specific EDID can be customized by following the operation process below.

1. Rename the user-defined EDID as EC_11.bin .
2. Connect the FW port of the controller to the PC using a USB cable, and then power on the controller, the PC will automatically detect a virtual disk named of “BOOTDISK”.
3. Double-click to open the disk, a file named of “READY.TXT” will be showed.
4. Copy the user-defined EDID to the “BOOTDISK” disk.
5. Reopen the disk to check the filename “READY.TXT” whether automatically becomes “SUCCESS.TXT”, if yes, the user-defined EDID was imported into the controller and saved as its corresponding EDID ID successfully.
6. Remove the USB cable, and then reboot the controller.
7. Now the new EDID can be invoked by setting the DIP switch status to “111”.

HDCP Mode

Put switch 4 on “ON” position to select HDCP Active mode, or to “OFF” for HDCP Passive mode.

System Control Setting

SYSTEM ON
When the controller detects a video signal via hot-plugging (5V HPD) or TMDS sensing (active video stream) or even an input IR signal, the system will start and automatically perform the actions below, all at the same time.

• Send CEC ON to turn on display.
• Send RS232 ON + Delay Time (default 3s, range of 1~180s) + User-defined RS232 command to display.
• Send IR ON + Delay Time (default 3s, range of 1~180s) + User-defined IR command to display.
• Toggle the state of relay 1 as follow.

SYSTEM OFF
When the controller detects that all input source devices have been removed or does not receive an IR signal within the delay time (default 10mins, range of 5mins-180mins), the system will turn off and automatically perform the actions below, all at the same time.

• Send CEC OFF to turn off display.
• Send RS232 OFF to display. The number of sending command is default 1 time, it can be set to 2 times by RS232 command.
• Send IR OFF to display. The number of sending command is default 1 time, it can be set to 2 times by RS232 command.
• Toggle the state of relay 2.

RS232 Command Setting

Trigger commands SYSTEM ON and SYSTEM OFF as well as CEC, RS232, IR and relay control actions can be set using RS232 commands.

RS232 Control Software

Installation: Copy the control software file to the PC which is connected to the controller.
Uninstallation: Delete all the control software files in corresponding file path.
The software CommWatch.exe is used as an example. Double-click the following icon:

The interface of the control software is shown as below:

• Please set the parameters of COM number, baud rate, data bit, stop bit and the parity bit correctly. The RS232 commands can then be sent using the Command Sending Area.
• Baud rate: 9600;
• Data bit: 8;
• Stop bit: 1;
• Parity bit: none.

Besides configuring IR control using RS232 commands. The IR commands can be learned from the IR remote by the SET button on the front panel.
Please follow the steps below to learn the IR commands from the IR remote:

1. Press SET to choose DISPLAY ON or DISPLAY OFF command to be set. DISPLAY ON LED: Flashing indicates that DISPLAY ON mode is selected. DISPLAY OFF LED: Flashing indicates that DISPLAY OFF mode is selected.
2. Point the IR remote at the SENSOR and press the respective button on the IR remote.
3. The DISPLAY ON or DISPLAY OFF LED will stop flashing and remain lit to indicate that IR command has been learnt.

1. Pressing and holding the SET button for 5 seconds can learn user-defined IR commands, and both DISPLAY ON and DISPLAY OFF LEDs are flashing. Then repeat the step 2 and both LEDs will stop flashing and remain lit to indicate that IR command has been learnt.
2. The IR learning mode will self-terminate after 10 seconds of inactivity. Both the DISPLAY ON and DISPLAY OFF LEDs will switch off when exiting the IR learning mode.
