EDID HTX series matrix switcher provides Auto EDID management system; easy and fail safe way to handle EDID, via EDID library system and EDID emulation.

What's EDID?

Extended Display Identification Data (EDID) is an information set that digital display provides to describe its capabilities to a Video source. Video source will know what kinds of displays are connected and it will determine which resolution to Output according to the EDID information received from the display.

The EDID normally includes manufacturer name and serial number, sets of capable resolution including native resolution, supported timing, pixel mapping data (for digital displays only) and etc.

In a digital connectivity environment; in order to support the maximum resolution of connected monitor, EDID handshake is a critical because improper EDID handshake between sources to the display will result in no image on the display.

EDID handshake may sound simple; however, with multiple peripheral devices within the chain, display's EDID information easily get lost or blocked while it is traveling to the source device.

HTX series matrix switcher provides Auto EDID management system to meet today's sophisticated digital connectivity integration environment.

Auto EDID management system

EDID library

15 most widely used EDID data is pre-programmed internal EEPROM chipset which user can take and save onto the any of the matrix switcher's Input EEPROM.

EDID library list

• 1080p, 2 ch audio 1080p, dolby/dts 5.1 1080p, HD audio
• 1080i, 2 ch audio 1080i, dolby/dts 5.1 1080i, HD audio
• 3D, 1080p, 2 ch audio 3D, 1080p, dolby/dts 5.1 3D, 1080p, HD audio
• 4K@30Hz, 2 ch audio 4K@30Hz, dolby/dts 5.1 4K@30Hz, HD audio
• 4K@60Hz, 2 ch audio 4K@60Hz, dolby/dts 5.1 4K@60Hz, HD audio

Note: Factory default EDID is set to 1920 x 1080p@60Hz

By optimizing factory default EDID and EDID library feature, in most cases, HTX series matrix switcher will work out of the box without any additional configuration.

Emulation

The user can easily save an EDID data from any display devices directly onto the matrix switcher’s input port. By saving display device's EDID information on the matrix switcher input port, input port will act as a display to the video source.

Note: There may be display devices that are not allowing other device to emulate its EDID data.

Note: Certain EDID data may not be compatible with some devices, in this case, it is recommended to use scaling option

Chapter 2. Communication Code Configuration

2.1 Control Programmer’s Guide (Code Structure and Examples)

This section is designed for programmers who wish to create their own control programs using the command code. All PureLink digital matrix routers provide a simple character stream control used by external control devices attached to a PureLink device. Command codes are used primarily for control, during system installation and setup, and for diagnostic purposes.

2.2 Overview

Command code is a set of alphanumeric characters that combine to form control commands. Command code strings are entered into a terminal emulation program (such as windows HyperTerminal) running on an external control device. The control device (PC, third-party controller) sends the commands to the system. Control devices must be able to send and receive ASCII or HEXA code via an RS-232 or Ethernet port.

2.3 Command Code Formats

A command code is a series of command characters and numbers used to send commands to the system. Commands include basic formulas for creating and disconnecting switches, as well as for verifying the status of switches.
In a command code, each character is either general command (e.g., C for connect) or an identifier that indicates what the following number designates (e.g., “O” and the number following it designate an “output number”). The command code *999CI01O01! can be interpreted as follows: (*) Starting the command code (999) Router ID is 999 (C) Create connection on (I01) Input 01 to (O01) Output 01 (!) take the command. For a complete list of command characters and their functions, see pages 16 -

Note: Ack value (Acknowledge value: Response from Pure Link device) will be echoed back to the terminal screen as the unit accepts them. When a command is successfully executed, all of the characters appear containing the character “s” which stands for status.

Ex 1) Command (Connect Input 1 to Output 1)
*999CI01O01! ↵
Ack value
*999sC I01O01!

Ex 2) Command (Check Input connection status on Output 3)
*999?O03! ↵
Ack Value
*999s? I03O03!

2.4 General Rules for Command Codes

The commands are coded in ASCII and HEXA. Please refer to Table 2.1 on pg. 17 for detailed descriptions of keys and functions. A basic command code setup is shown below;
Ex) *999CI01O01! ↵
Start (*) + Router ID (999) + Command (C) + Input number (I01) + Output number (O01) + End (!) + Enter (↵ )

• A command line allows execution of only one command. Multiple commands require execution of multiple strings; one command per string.
• All s begin with * (Start) byte.
• All s end with ! (End) byte.
• All s will be executed when ↵ (Enter) is entered.
• The correct Router ID must be entered in a command code. Systems will not react to the command if a wrong Router ID is entered. The Factory Default Router ID is set to 999 and the universal Router ID is 999. Systems will react to the command whenever universal Router ID is entered in command code.
• Command codes typically are not case-sensitive.
• To specify multiple inputs and outputs, enter a “,” (Comma) between numbers. (Ex., *999CI01O01,02,03! ↵ : Connects Input 01 to Output 01, 02, and 03)
• Use - (Hyphen) for range connection. (EX., *999CI01O01-04! ↵ : Connects Input 01 to Output 01,02,03, and 04)

Table 2.1 Command Codes Characters Table

The table below shows command code characters (keys), which are used to generate control commands, their functions, and short function descriptions.

2.5 Command Ack (Acknowledge) Value Response

When command codes are entered into a terminal emulation program (such as HyperTerminal) and are accepted by the system, they respond back to the terminal screen one at a time, as noted below in the table. The complete command has executed successfully when all of the entered characters including “s” which stands for status, appear. If a command character is not accepted, a different character than the one entered appears and all or part of the command has not been executed.

Ack (Acknowledge) Value Response Table

Command Code Ack Value Examples

2.6 Connecting Switches

A switch is an active connection between an input (source) signal and one or more output (display) devices. The signals connected in a switch command are either individual signals or groups of signals coming through the connectors on the rear of the unit.
The “C” key initiates a Connect command for routing a switch. The characters and numbers that follow the “C” command tell the system, which inputs and outputs to connect. The last character “!” is found at the end of a command code which tells the system to execute the command.
For example, the command code *999CI01O01! ↵ can be interpreted as follows: (*) Starting the command code (999) Router ID is 999 (C) Create connection on (I01) Input 01 to (O01) Output 01 (!) take the command. For a complete list of command characters and their functions, see examples below.

1. Enter the Connect command below. Replace the “#”s with the input and output number(s).
2. *999CI#O#! ↵

Examples (Connect) :

*999CI01O01-04!Connect Input 1 to Output 1, 2, 3, and 4

*999PTP!Connect Input 1 to Output 1, Input 2 to Output 2, Input 3 to Output 3 and Input 4 to Output 4

Disconnecting Switches

The characters and numbers in a Disconnect command tell the system which input or output to disconnect. The “D” key initiates a Disconnect command for routing a switch. The characters and numbers that follow the “D” command tell the system that inputs and outputs to disconnect. The last character “!” is found at the end of the Command code, which tells the system to execute the command.
For example, the command code
*999DI01O00!
It can be interpreted as follows: (*) Starting the command code (999) Router ID is 999 (D) Disconnect on (I01) Input 01 to (O00) Output 00 (!) take the command. For a complete list of command characters and their functions, see the command list below

1. Enter the Disconnect command below. Replace the “#”s with the input and output number(s).

Status Check

A connection status can be checked to confirm that the switch has been correctly executed or to confirm correct routing to multiple outputs. The characters and numbers in a status command tell the system which input or output to check.

1. Enter the Connection status check command below. Replace the “#”s with the input and output number(s).
