Frequently Asked Questions - DCE-1 AMX

What is the AMX DCE-1 used for?

The AMX DCE-1 is an in-line controller that provides EDID emulation, CEC control, and audio de-embedding for HDMI signals. It ensures reliable video output, automatic display on/off, and audio extraction for amplification or processing.

How do I set the EDID on the DCE-1?

Use the rotary switch on the rear panel to select an EDID preset (positions 0-15). Position 0 copies the EDID from the connected display. Other positions offer fixed resolutions up to 4K60. After changing the switch, reboot the device for the new EDID to take effect.

What audio outputs does the DCE-1 support?

The DCE-1 offers two audio outputs: digital S/PDIF (RCA coaxial) supporting up to PCM 5.1, Dolby Digital, and DTS 5.1; and analog stereo via a 3-pin phoenix connector supporting 2-channel PCM.

Can the DCE-1 control a projector or screen automatically?

Yes. The DCE-1 can send CEC or RS232 commands to power displays on/off when a video signal is detected or lost. It also has relay outputs to control projection screens. Pre-load RS232 commands using the API.

How do I configure RS232 commands for display control?

Connect a PC to the DCE-1 RS232 port via a USB-UART cable. Use terminal software at 9600 baud to send API commands like CPW1PSONONT to store power-on strings. Then connect the display to the DCE-1 RS232 port for automatic control.

What resolutions and HDCP versions are supported?

The DCE-1 supports resolutions up to 4K60 4:4:4 and is compatible with HDCP 1.4 and 2.2. It can handle VESA and CEA timings including 3840x2160 and 4096x2160.

Is the DCE-1 firmware upgradeable?

Yes, the DCE-1 supports firmware upgrades via the RS232 port using the ~UPG! command. Refer to the API command list for upgrade instructions.

What should I do if there is no video output?

First, ensure all devices are powered and LEDs are on. Check HDMI cables and try a different cable. Verify the EDID switch setting matches the display's capability. Test directly connecting source to display to isolate the issue.

Can I use the DCE-1 with a non-AMX system?

Yes, the DCE-1 works as a standalone device with any HDMI source and display. RS232 control can be customized for any brand using the API command set.

How do I clean and maintain the DCE-1?

Clean the exterior with a dry cloth only. Do not use liquids or sprays. The device has no user-serviceable parts; refer all servicing to qualified personnel. Keep away from moisture and heat sources.

ESD WARNING

To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before touching any internal materials.When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive smocks, and conductive work mats are specifically designed for this purpose. These items should not be manufactured locally, since they are generally composed of highly resistive conductive materials to safely drain static discharges, without increasing an electrocution risk in the event of an accident.Anyone performing field maintenance on AMX equipment should use an appropriate ESD field service kit complete with at least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another ground cord.

WARNING: Do Not Open! Risk of Electrical Shock. Voltages in this equipment are hazardous to life. No user-serviceable parts inside. Refer all servicing to qualified service personnel.

Place the equipment near a main power supply outlet and make sure that you can easily access the power breaker switch.

WARNING: This product is intended to be operated ONLY from the voltages listed on the back panel or the recommended, or included, power supply of the product. Operation from other voltages other than those indicated may cause irreversible damage to the product and void the products warranty. The use of AC Plug Adapters is cautioned because it can allow the product to be plugged into voltages in which the product was not designed to operate. If the product is equipped with a detachable power cord, use only the type provided with your product or by your local distributor and/or retailer. If you are unsure of the correct operational voltage, please contact your local distributor and/or retailer.

WARNING: Avoid exposure to extreme heat or cold.

EDID Management

EDID (Extended Display Identification Data) is a data structure provided by a digital display to describe its capabilities to a video source.

The DCE-1 features multiple EDID presets which can be performed using the EDID rotary switch on the rear panel. By default, the EDID switch is set in position 0. Should any compatibility issues occur, use the following table for the EDID setting:

Position Description
0 (default) Copy EDID from HDMI OUT
1 Set 3840x2160@60Hz	2CH as input EDID
2 Set 3840x2160@30Hz	2CH as input EDID
3 Set 1920x1080@60Hz	2CH as input EDID
4 Set 1280x720@60Hz	2CH as input EDID
5 Set 1920x1200@60Hz	2CH as input EDID
6 Set 1680x1050@60Hz	2CH as input EDID
7 Set 1600x1200@60Hz	2CH as input EDID

E Set1280x768@60Hz	2CH as input EDID
F Set 1024x768@60Hz	2CH as input EDID

Note:

1. If EDID copy fails, 1920x1080@60Hz with stereo audio will be set as the Input EDID.
2. For the EDID settings to take effect, the DCE-1 must be re-booted.

RS232 Control

The RS232 port allows control of the DCE-1 or connected display through RS232 commands. The following diagram shows the RS232 pinout. Connect with the provide Phoenix Connector.

RS232 Port Connected RS232 Device Pins

DCE-1 Control

Connect a control PC to the DCE-1 via a USB-UART cable, and run a terminal emulation program on your PC to configure the connection parameters correctly. The baud rate for the DCE-1 is 9600. This allows execution of RS232 commands through the software. For more information, refer to the API Command List Instructions at the end of this document.

Example:

Command:

CUB1T

Response:

CUB1T

Explanation:

UB#: # = {1-6}

1. 9600
2. 14400
3. 19200
4. 38400
5. 56000
6. 57600

This command is used to set baudrate for the serial portto 9600.

Display Control

To control a display (Projector, etc.) through pre-loaded RS232 commands, configure the RS232 port of the DCE-1 according to the display parameters.

1. Connect a PC to the DCE-1 according to section "Control the DCE-1".
2. Configure RS232 parameters of the DCE-1 with the serial port software according to the display parameters. For example: set the correct baud rate, preload Power-ON and Power-OFF commands in string/hex (refer to the document "API Command Set_DCE-1).
3. Disconnect the PC from the DCE-1, and connect the display according to the diagram on page 6. The DCE-1 can automatically execute RS232 commands to Power ON or OFF the connected projector and projection screen when an input signal change is detected.

Troubleshooting

Power: Ensure all devices are powered on.

Indicator: Ensure all LED indicators of the DCE-1 are normal according to the user manual.

Devices: Ensure picture can be shown normally when directly connecting a source to a display device.

Cable: Plug the HDMI cable in and out or connect a different HDMI cable. Ensure the specific cable length is within the available transmission range according to the Specifications Section.

EDID: There are multiple EDID presets depending on the EDID rotary switch setting. Please refer to the EDID Management Section to ensure the display works properly.

Compatibility: Test other source and display devices to determine correct compatibility.

API Command List Instructions

General Rules for Using BCS Commands

• Command strings typically are not case-sensitive.
• All command strings must end with the Take command "T" which tells the system to execute the command.
• “O” is the letter O, not the number zero (0).
• Entering "X" at any point in a command string cancels the command.

- A command cannot be canceled after the "T" has been entered.

- Command strings cannot be edited. If a mistake has been made, enter an "X" and then reenter the command.

- To specify multiple outputs, inputs, levels, or local presets, enter a space “” between each number. Multiple

- inputs are only valid in Disconnect commands.

- To specify a range of outputs, inputs, or local presets, insert a colon ":" between the lowest and highest numbers of the range (not supported if the command is otherwise invalid, e.g., cannot specify a range of inputs in a Change command; the first input only would be routed).

- Colons ":" and spaces " " can be used in the same command string.

- If the level designation "L" is omitted, the command is executed on the default level, which is normally Level 0.
