Product Introduction

The PT-SW-HD41E is an ultrathin auto switcher with four HDMI video inputs and one HDMI output. This switcher supports HDMI video resolution up to 4Kx2K@60Hz 4:4:4 HDR and multichannel audio. Except passing EDID information from the display, there are multiple built-in EDID settings to simplify an installation. The switcher will de-embed digital stereo audio to provide an analog audio source for an existing audio system. The switcher also supports audio return channel (ARC) for transmitting audio back to HDMI input port from the connected display.
In auto-switch mode, it switches to an HDMI input as soon as a new source is connected. When the active input is removed, the switcher will select the first source on the lowest numbered input. The switcher may also be controlled via RS232, IR with the included remote, or from the source button on the front of the switcher.

Manual Switching

When the switcher is in manual switching mode, the Switching Mode LED will be green, and please press Auto/Source button to switch to the next input.

Automatic Switching

To enable automatic switching, press and hold the Auto/Source button for three seconds. The Switching Mode LED will turn to yellow.

When in auto-switch mode, the switcher follows the rules in the certain circumstances:

• New Input: Upon detecting a new input, the switcher will automatically select the new source.
• Reboot: Once power is restored to the switcher, if the last selected source is still available, the switcher will still output this signal, otherwise, the switcher will switch to the first available active input starting at HDMI Input 1.
• Source Removed: When an active source is removed, the switcher will switch to the first available active input starting at HDMI Input 1.

IR Remote Control

Please connect an IR receiver to the IR input port; the IR remote is used for signal switching and it can also be used to control source and display devices based on CEC function.

Note: Due to the HDMI input 4 port does not support CEC, the source device connected to this port can not be controlled by IR remote.
The source and display devices are required to support CEC when the IR remote is used to control them.

INPUTS:
1~4: Select the corresponding input source.
MANUAL/AUTO: Switch Auto or manual mode.
SOURCE: Control the input source (e.g. DVD).
DISPLAY: Control the display (e.g. HDTV).

RS232 Control

Connect the switcher to the control device (e.g. PC) with RS232 cable and set the parameters in the right manner, the control device is capable to control this switcher by RS232 commands.

RS232 Control Software

Installation: Copy the control software file to the computer connected with this switcher.
Uninstallation: Delete all the control software files in corresponding file path.

Basic Settings
First of all, please connect all needed input devices and output devices, then to connect it with a computer which is installed with RS232 control software.
Here take the software CommWatch.exe as example.
Double-click the following icon:

The interface of the control software is shown as below:

Please set the parameters of COM number, bound rate, data bit, stop bit and the parity bit correctly, then the RS232 commands can be sent in Command Sending Area.

System Control

Predefined EDID Setting

The rear panel boasts a 4-pin DIP switch to set the predefined EDID. The ten types of embedded EDID and their corresponding switch status are shown in the below list.

When in the lower position, the switch represents “ON”, while putting the switch in the up position, it represents “OFF”.

User Defined EDID Setting

Except directly invoking the embedded EDID, the specific EDID can be customized. There are five EDID can be customized following the below operations.

1. Rename the user defined EDID according the following format. EC_xx_xxxx_xxx.bin EC: Represents EDID. xx: Represents EDID ID. It is 11~15. xxxx: Represents the video parameter. xxx: Represents the audio format. Example: EC_11_720P_LPCM.bin
2. Power on the switcher, and then connect the switcher to the PC with USB cable. The PC will automatically detect a U-disk named of “BOOTDISK”.
3. Double-click the U-disk, a file named of “READY.TXT” would be showed.
4. Copy the user defined EDID (such as EC_11_720P_LPCM.bin) to the “BOOTDISK” U-disk.
5. Reopen the U-disk to check the filename “READY.TXT” whether automatically becomes “SUCCESS.TXT”, if yes, the user defined EDID was imported into the switcher and saved as its corresponding EDID ID successfully.
6. Repeat the above third to fifth step to copy other user defined EDIDs to the “BOOTDISK” U-disk.
7. Remove the USB cable, connect the adaptor to power on the switcher.
8. The new EDID also can be invoked via the 4-pin DIP switch directly. The EDID ID and its corresponding switch status are shown in the below list.

ARC Mode

Audio Return Channel (ARC) allows audio from a display to pass “upstream” through an HDMI cable to an audio processing device, such as an AV amplifier. When ARC mode is active on the switcher, the ARC stream will pass to the active HDMI source device if it can process the signal.

Only the fourth HDMI input port features ARC, when the display and AV amplifier support ARC, the audio connection diagram is shown below:

Firmware Upgrade

Please follow the steps as below to upgrade firmware by the Micro-USB port on the rear panel:

1. Prepare the latest upgrade file (.bin) and rename it as “USERAPP.bin”
2. Connect the switcher to the PC with USB cable, and then power on the switcher. The PC will automatically detect a U-disk named of “BOOTDISK”.
3. Double-click the U-disk, a file named of “READY.TXT” would be showed.
4. Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk.
5. Reopen the U-disk to check the filename “READY.TXT” whether automatically becomes “SUCCESS.TXT”, if yes, the firmware was updated successfully, otherwise, the firmware updating is fail, the name of upgrade file (.bin) should be confirm again, and then follow the above steps to update again.
6. Remove the USB cable after firmware upgrade.
