When the matrix is in standby mode, operations using the front-panel buttons are suspended. However, access to the matrix, through the web GUI or API commands is still available.

1. Press the POWER button again, to power-on the matrix and return to normal operating mode.

NOTE: Firmware version 16.1.18 supports a front-panel display time-out feature. If there is no front-panel activity after 30 seconds, the front-panel display will turn off. The time-out feature only hides the text in the front panel display. Initiating a routing command, for example, or other operation will turn on ("wake up") the front-panel display and the matrix will wait for the next command to be entered.

Viewing Matrix Settings

The front panel display provides the current status of the matrix and its settings. The buttons on the front panel can be used to display the current routing settings as well as network settings.

EDID Management

EDID is an acronym for Extended Display Identification Data. Before a source can send a picture and/or audio to a display (or other sink device), the source requests information from the display on what video and audio formats it can support. Once the source has this information, it will send the supported picture and audio resolution that is supported by the display. By default, the AT-UHD-PRO3-66M loads a "default" EDID on all inputs. This particular EDID provides the source with the highest common resolution and audio information that is supported by all connected displays.

For example, if the matrix is connected to a single 1080p display and two 4K/UHD displays, the 1080p resolution will be used, allowing all three displays to display a picture. However, there may be instances where a specific EDID is desired. The AT-UHD-PRO3-66M allows EDID data to be stored, loaded, and copied.

Loading EDID Presets

Using the Front Panel

The AT-UHD-PRO3-66M provides 14 pre-programmed internal EDID selections. These EDID presets can be loaded to any one of the six inputs (HDMI or HDBaseT). Custom EDID data can also be copied to any input. Refer to Copying a Downstream EDID (page 40) for more information.

Advanced Operation

RS-232 Control

The AT-UHD-PRO3-66M provides RS-232 control between an automation system and an RS-232 device using a captive screw connector block. The AT-UHD-PRO3-66M provides two modes of RS-232 control: Pass-through mode and control mode.

RS-232 is serial data protocol that allows Data Terminal Equipment (DTE) devices, such a computer or control system, to communicate with Data Communication Equipment (DCE) devices, such as the AT-UHD-PRO3-66M, amplifier, or display. Although IP control is available, RS-232 still plays an integral part of many control systems.

Although the 25-pin D-type connector (DB-25) was defined as the RS-232 standard, it is now commonly implemented in a nine-pin (DE-9) connector package and is numbered, as shown below.

DE-9 (male) DE-9 (female)

DTE Pin Descriptions

Pin Signal Description
1 DCD	Data Carrier	Detect
2 RxD	Receive Data
3 TxD	Transmit Data
4 DTR	Data Terminal Ready
5 GND	Ground (Signal)
6 DSR	Data Set Ready
7 RTS	Request to Send
8 CTS	Clear to Send
9 RI Ring Indicator

DCE Pin Descriptions

Pin Signal Description

2 TxD	Transmit Data
3 RxD	Receive Data
4 DSR	Data Set Ready
5 GND	Ground (Signal)
6 DTR	Data Terminal Ready
7 CTS	Clear to Send
8 RTS	Ready to Send
9 RI Ring Indicator

Determining the Port Type

Most DTE devices provide a male connector, while DCE devices have a female connector. However, this is not always the case. If the port type is unknown, then a multimeter can be used to determine whether the port is DTE or DCE:

1. Turn on the multimeter and set it to measure DC voltage.
2. Connect the positive and negative leads to pins 3 and 5, respectively.
3. Check the voltage reading:

If the voltage is between -3 V DC and -15 V DC, then the device is DTE. Otherwise, it is DCE.

Voltage levels between -3 V and -15 V DC represent a logic "1". Voltage levels between +3 V and +15 V DC represent a logic "0".

Cable Assembly

When connecting a DTE device to a DCE device, a straight-through cable should be used. A straight-through cable is wired in such a way that the pins on one side of the cable are connected to the corresponding pins on the opposite side of the cable, as shown in the table below. However, the AT-UHD-PRO3-66M will use only TxD, RxD, and GND signals when communicating with a control system or computer.

Straight-Through Cable

Pin Signal Signal Pin
1 DCD DCD 1
2 RxD TxD 2
3 TxD RxD 3
4 DTR DSR 4
5 GND GND	5
6 DSR		DTR 6
7	RTS		CTS	7
8	CTS		RTS	8
9 RI		RI	9

1. Identify the DE-9 connector that will be attached to the control system or computer (DCE) equipment.
2. Remove the DE-9 connector at the opposite end of the cable with wire cutters.
3. Remove at least 1" of the cable insulation to expose each of the nine wires.
4. Locate a multimeter and set it to the "continuity" function.
5. Attach one of the leads from the multimeter to pin 2 on the DE-9 connector.
6. Take the other lead and probe each of the wires on the opposite end of the cable. When the wire connected to that pin is detected, the multimeter will emit an audible tone. Once this occurs, identify the current wire, and move it to the side.
7. Repeat step 6 for pin 3 and pin 5 on the DE-9 connector.
8. Group the remaining wires and pull them aside. Electrical tape can be use to secure the wires to the outside of the RS-232 cable.
9. Remove at least 3/16" (5 mm) of insulation from the TxD, RxD, and GND wires.

1. Locate the included 3-pin captive screw block and open each of the terminals by turning the screws counter-clockwise, using a small regular screwdriver.
2. Insert the TxD, RxD, and GND wires into correct terminal, as shown, and tighten the screws to secure each wire. Do no overtighten.
3. Connect the captive screw connector to the RS-232 port on the AT-UHD-PRO3-66M.

Control mode

In control mode, RS-232 commands are sent from a computer or control system (DTE) to the AT-UHD-PRO3-66M (DCE). This method allows direct control of the matrix for routing, IP configuration, powering-on / powering-off and other functions.

NOTE: The RS-232 port on the AT-UHD-PRO3-66M runs at a default baud rate of 115200.

The control unit must be set to the same baud rate, in order to communicate with the AT-UHD-PRO3-66M.

1. Connect the RS-232 cable between the control system and the AT-UHD-PRO3-66M. Refer to Cable Assembly (page 47) for instructions on preparing the cable.
2. Set the baud rate of the computer/control system to 115200. If the control system is not set to this baud rate, then the AT-UHD-PRO3-66M will not respond to RS-232 commands.
3. Refer to the Applications Programming Interface for a listing of available commands.

IR Control

The AT-UHD-PRO3-66M feature six IR IN ports and six IR OUT ports. Devices at either the headend or connected to the receiver unit can be controlled using IR.

The following shows how to control displays (or other sink devices) which are connected to an HDBaseT receiver. Each IR IN port provides IR control for two individual HDBaseT receivers (outputs).

1. Remove at least 3/16" (5 mm) of insulation from both the GND and Signal leads.
2. Locate the included 4-pin captive screw block and open each of the terminals by turning the screws counterclockwise, using a small regular screwdriver.

1. Insert the GND and Signal leads into correct terminal, as shown, and tighten the screws to secure each wire. Do no overtighten.
2. Connect the captive screw connector to the IR IN ports on the AT-UHD-PRO3-66M.

Controlling Display Devices

The following shows how to control displays (or other sink devices) which are connected to an HDBaseT receiver. When a control device is connected to an IR IN port, the IR signal is transmitted over Ethernet cable, from the associated ZONE OUT port, to the HDBaseT receiver. IR IN ports are “hard wired” to each ZONE OUT port. For example, IR IN 1 is wired to ZONE OUT 1ED, IR IN 2 is wired to ZONE OUT 2ED, and so on. IR IN ports cannot be routed independently.

IMPORTANT: IR IN ports cannot be routed independently. Each IR IN port is associated with a ZONE OUT port: IR IN 1 > ZONE OUT 1ED, IR IN 2 > ZONE OUT 2ED, and so on.

1. Connect the IR output of the control system to the IR IN ports on the AT-UHD-PRO3-66M, using the included 4-pin captive screw connector blocks. Refer to Cable Assembly (page 51) for more information.
2. Connect an Ethernet cable from the desired ZONE OUT port on the AT-UHD-PRO3-66M to an HDBaseT receiver. Note that the IR IN port and the ZONE OUT port numbers must match. For example, in order to send IR commands over the ZONE OUT 4 port, the IR port of the control system must be connected to IR IN 4 on the AT-UHD-PRO3-66M. This example is illustrated, below.

Controlling Headend Devices

Source devices (at the headend) can be controlled from the viewing location. IR control depends upon the current routing state: only the currently viewed source can be controlled using IR.

1. Connect the IR receiver (AT-IR-CS-RX) to the HDBaseT receiver, at the viewing location. Although a control system can be used, a basic IR receiver is commonly used.
2. Connect an IR emitter to the desired IR OUT port on the AT-UHD-PRO3-66M. Make sure the source device is within range of the IR emitter.

In the example below, the HDMI IN 4 has been routed to ZONE OUT 2. The IR remote control for the Set Top Box (STB) is connected to the HDBaseT receiver (AT-UHD-EX-100CE-RX) on ZONE OUT 2. As long as the STB is routed to ZONE OUT 2, the STB can be controlled from the viewing location. If a different source is routed to ZONE OUT 2, then the STB can no longer be controlled from the viewing location, using IR.
