1. 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.
1.1 Features
Supports up to 4K@60Hz, 4:4:4 with HDR10 and Dolby Vision support, HDCP 2.2
compliant.
HDCP pass-through or conversion to HDCP 1.4 for better compatibility.
Supports 4K to 1080p down-scaling.
Comprehensive EDID management with 8 EDID options for various applications.
Display control options via CEC, RS232 and IR.
Contact closure input for the connection with a variety of periphals, such as
sensors and switches.

5. DIP Switch Operation
5.1 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.

Multi-CH: Supports LPCM 8CH, Dolby TrueHD, DTS-HD , Dolby Digital5.1, 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”.
