Epson Projector Control Driver v1.41

Smart Home Programming

Controls Epson projectors via ESC/VP21 protocol over TCP/IP (ESC/VP.net port 3629) or RS-232 serial.

Supported Models:

- EH-TW9400 / EH-TW8400 and other EH-series (home cinema)

- H619B / EB-series / EB-L / EB-W (business projectors)

- Any Epson projector supporting ESC/VP21 protocol

Setup

Projector Family:

Select EB/H-series for business projectors (H619B, EB-G, EB-L, EB-W etc.) or EH-series for home cinema models. This affects OSD navigation key codes and volume control.

TCP/IP Connection (recommended):

1. Connect projector to your network

2. Enable Network control in the projector's Network menu

3. Set Transport = TCP/IP

4. Enter the projector's IP address

5. Port defaults to 3629 (ESC/VP.net)

Serial Connection:

1. Connect RS-232 cable (9600 baud, 8N1)

2. Set Transport = Serial

3. Select the serial port from the dropdown

Input Configuration

Configure up to 8 input slots with custom names and ESC/VP21 source codes. All 8 slots appear in Integration Designer's macro/variable lists with their configured names.

Common Source Codes (EH-series / Home Cinema):

- 30 = HDMI 1

- A0 = HDMI 2

- C0 = HDMI 3

- 10 = VGA 1

- 20 = VGA 2

- 80 = HDBaseT

- 53 = LAN

- 52 = USB

- 56 = Screen Mirroring

- 54 = WirelessHD

Common Source Codes (EB/H-series / Business):

- 30 = HDMI 1

- A0 = HDMI 2

- 11 = Computer 1

- 21 = Computer 2

- 41 = Video

- 51 = USB Display

- 52 = USB

- 53 = LAN

- 56 = Screen Mirroring

Use the "Scan Available Inputs" button (right-click the driver in Integration Designer) to automatically discover which inputs your projector supports.

Volume

EH-series: Volume is queried every poll cycle (VOL? command, range 0-20). The Volume system variable reflects the actual hardware level.

EB/H-series: Projectors do not support the VOL? query. Volume is tracked optimistically - the Volume variable is incremented/decremented on each key press. Audio-only mute (KEY D3) is not supported on EB/H-series; use A/V Mute instead.

Debug Console

A TCP debug console is available on the configured Debug Console Port (default 12513). Connect via the included tools/epson_debug_console.py tool:

python tools\epson_debug_console.py [processor_ip] [port]

Available commands: status, power on/off, source, mute on/off, query <cmd>, send <cmd>, sourcescan, getsources, scan eb, dbg, help

Notes

- The projector must have network standby enabled (Standby Mode = Communication On) to be woken via TCP/IP

- Power On takes up to 100 seconds for lamp warm-up

- A/V Mute blanks BOTH video and audio, not audio-only

- EB/H-series OSD navigation uses different key codes than EH-series - select the correct Projector Family in settings

- HDBaseT source code is 80 on EH-series; confirm on EB/H-series via debug console
