Chapter 3: Installation

4.    Make any required configuration changes via the LED/button user interface, if the receiver is equipped with this capability. This 

is for skew compensation.

5.   Adjust the receiver’s EQ and/or SKEW (optional) settings. 

NOTE: If this adjustment is not made, it can result in a poor or no image on the display.

3.3 Configuration 

The transmitter has a number of configurable operating parameters, and the factory-default settings will work in most  
applications. However, some applications may require configuration changes. Nearly all settings are available from the front-panel 
buttons/LEDs. The enclosure does not need to be opened; there are no user-configuration settings or jumpers inside.

3.3.1 DDC Mode Selection

The CAT5 Multi VGA and Analog Audio Transmitter features the ability to send DDC/EDID display identifiers to the video source 
to determine display capabilities. The DDC/EDID interface is a data communications channel used between plug-and-play devices 
to accurately report a display's capabilities and identify the manufacturer. If this data is not available, the video source may revert 
to a low resolution or not display at all. The transmitter has three DDC/EDID modes of operation. When the T4 is operating in 
“normal mode” (CFG indicator is off), you can quickly select between the three operating modes simply by using the DDC MODE 
button at any time:

•  STD: Selects the default DDC profile (a default set of common video resolutions). Press the DDC MODE button until the STD 

indicator (LED 6) is on. This is the factory default setting.

•  LOCAL: Selects the DDC profile from a locally connected display. Press the DDC MODE button until the LOCAL indicator (LED 7) 

is on. The LOCAL mode allows the video source device to directly read the DDC profile from the locally connected display (if 
present). 

NOTE: LOCAL mode does not store any DDC profile information inside the transmitter.

•  COPY: Selects a previously stored copy of a DDC profile. Press the DDC MODE button until the COPY indicator (LED 8) is on. To 

use the COPY mode, a DDC profile must have already been read and stored into the transmitter.

• To perform a DDC-copy operation, make sure the COPY mode is selected (LED 8=on), then:

1. Connect a display to the LOCAL OUT port.

2.  Push and hold the COPY button until the copy-status indicator flashes three times, indicating a successful operation. If it only 

flashes once, the operation failed, and the previously stored DDC profile (if any) will remain unchanged.

3. If desired, disconnect the display from the LOCAL OUT port.

3.3.2 General Configuration Settings

For all other configuration settings, the transmitter must be in CONFIG mode (CFG indicator is on). Once in CONFIG mode, any 
changes are effective immediately and are saved in non-volatile memory.

•  To enter configuration mode1: Press the CFG button once. The CFG indicator will light, confirming that you are in configuration-

mode 1.  Once in this mode, the LED indicators 1–8 will display the current settings as described in Tables 3-1 through 3-4.

•  To enter configuration mode2: Press CFG button twice. The CFG indicator will flash, confirming you are in configuration-mode 

2.  Once in this mode, the LED indicators 1–8 will display the current settings as described in Tables 3-1 through 3-4.

• To exit configuration mode: Leave the buttons untouched for 10 seconds. The CFG indicator will turn off (normal mode).

3.3.3 Setting Factory Defaults

To quickly reset all user-configurable options back to factory default settings:

1. Disconnect the DC power cable (or AC power).

2. Press and hold the CFG button.
