Getting Started
The Dashboard software is design to allow you to quickly access the feature sets of openGear form factor cards on a simple User Interface. This section will help you get up and running as quickly as possible.

Running Dashboard
Before you can successfully run the Dashboard software for the first time you must first download it from https://www.opengear.tv/frame-and-control/control-system/download/. Run the downloaded setup file and choose an appropriate installation location on your computer’s storage. Now you can run the Dashboard by double clicking on the Dashboard icon.

OG-DA-AV Dashboard
OG-HDM2.0-1×2-Dual is a very straight forward plug and play card. The Dashboard interfaces are as follows:

Onboard Buttons

7-segmented Display
Display Information The seven-segment display is generally in a non-display state. Pressing the menu button will wake up the seven-segment display to show information or enter operation mode. If there is no operation for 3 minutes, the seven-segment display will return to the non-display state. The first digit on the left indicates the menu page, while the remaining three digits represent functions or values.

Menu Button

Functional Block Diagram

Onboard Operations

Menu 1
Input loop or Termination (Loop setting is generally used for connecting multiple cards in series. Termination is typically used for a single card or for the last card in a series connection)

As shown in the figure below, Menu 1
Function set to 0 indicates that the input is configured as Loop (hi-Z) input.

As shown in the figure below, Menu 1
Function set to 1 indicates that the input is configured as Termination (75Ω) input.

Menu 2
Gain Adjustment
The adjustment range is from 0 to 100, with each unit corresponding to approximately 9.4 to 9.5 mV.

0 = 0V
1 = 0.1040V
100 = 1.0398V
This range translates from 0V to 1V, representing a gain of 0 dB to 3 dB.

As shown in the figure below, Menu 2
Value set to 0.

As shown in the figure below, Menu 2
Value set to 100.

When a signal is transmitted through a long cable, signal loss occurs. If the video becomes dim, the Gain value can be adjusted to compensate for the signal loss, making the video brighter.

Menu 3

EQ Value Adjustment
The adjustment range is from 0 to 100, with each unit corresponding to approximately 9.4 to 9.5 mV.

0 = 0V
1 = 0.1040V
100 = 1.0398V

This range translates from 0V to 1V, representing a gain of 0 dB to 20 dB at 120 MHz.

As shown in the figure below, Menu 3
Value set to 0.

As shown in the figure below, Menu 3
Value set to 100.

When a signal is transmitted through a long cable, signal loss occurs. If the video becomes blurry, the EQ value can be adjusted to compensate for the signal loss, making the video clearer.

Menu 4
Input Single-Ended or Differential
Set the input to either single-ended or differential. This setting applies to the BNC connectors labeled “IN” on the backplane.

As shown in the figure below, Menu 4
Function set to 0 indicates that the input is configured as Single-Ended input.

As shown in the figure below, Menu 4
Function set to 1 indicates that the input is configured as Differential input.

As shown in the figure below, Menu 5
Function set to 1 indicates DC Coupling Clamping (The input signal, after passing through the EQ/Gain circuit, is connected to the slow clamping circuit before being sent to the 1×8 splitter output inside the card).

As shown in the figure below, Menu 5
Function set to 2 indicates DC Coupling Fast Clamping (The input signal, after passing through the EQ/Gain circuit, is connected to the fast-clamping circuit before being sent to the 1×8 splitter output inside the card).
