[CEC] must be checked to enable CEC and to apply the selected dropdown options to the VRROOM unit. Once activated it allows VRROOM to answer and process CEC requests and commands and appear on the TV CEC network map. Uncheck it if you do not want VRROOM to answer external CEC requests or process Internal CEC commands. Unchecking will remove VRROOM from the CEC Root(TV) network map but CEC commands for connected sinks or sources will still pass-thru.

[CEC TYPE] Audio Processor (Default) is the device type to choose if you want VRROOM eARC/ARC feature to be ON and retrieve sound from TV ARC/eARC to VRROOM HDMI audio out or eARC OUT, 5.1 Optical Out or Jack Analog Stereo output. Unit must be restarted after any CEC Type change. In some cases TV restart can be needed as well.

[CEC TYPE] Video Processor is the device type to choose if you have an AVR or sound system in your setup and if you use or want to use that AVR or sound system for ARC/eARC or CEC. Unit must be restarted after any CEC Type change. In some cases TV restart can be needed as well.

[eARC/ARC]: Select between AUTO (default), MANUAL HDMI or MANUAL eARC/ARC option. VRROOM can extract up to Atmos over DD+ for ARC TV offering such option and up to full audio Atmos over True HD for eARC TV. ARC/eARC extraction retrieve audio from either others devices directly connected to TV or from TV embedded streaming APPS and forward it to any AVR or sound system input via the VRROOM HDMI audio out or to any AVR or Sound system ARC/eARC output via the eARC/ARCANA output or even via optical output for a setup with ARC TV. Please note that only a very few AVR on the market can support 192kHz via optical that could support Atmos/DD+, they are usually limited to DD 5.1 via optical.

[SEND CEC TEST COMMAND]: Enter the CEC command of your choice in this text field in HEX format. If you are not sure about how to format your command, we recommend you to visit the very well done cec-o-matic website made by Kwikwai.

[RS232 COMMAND]: Allow you to test RS232 command to make sure your unit is properly configured and ready to communicate via RS232.

[RS232 BAUD RATE]: Set the RS232 link speed (default 19200)

[Send Ascii]: Once RS232 command have been entered in Ascii format, use this button to send it out.

[Send Binary]: Once RS232 command have been entered in HEX/Binary, use this button to send it out.

[REFRESH]: Refresh the current page.

Note: CEC/ARC master is TX0, if you want ARC or eARC from the TV; you need to connect your TV ARC/eARC capable input to VRROOM HDMI TX0 OUTPUT and set the unit as Audio Processor under VRROOM CEC device type.

With the help of power users from the community, special automatic and custom macro has been developed for JVC Projectors. Kindly please refer to instructions posted here. VRROOM now allow to edit each command individually so you can instruct any RS232 capable display.
