What is 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 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.
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.
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(s):
 There may be display devices that are not allowing other device to emulate its EDID data.
 Certain EDID data may not be compatible with some devices, in this case, it is recommended to use
scaling option

IR Control
The matrix is not only a switcher and extender of multiple HDMI signals to HDMI receivers located
remotely, it also passes IR control signal through the IR call-back system to the matrix and HDMI
sources. Two-way IR Call –back between matrix, sources and displays from multiple locations. A key
feature on matrix is discrete IR control of the matrix, sources and displays from any location –so inputs
at the matrix end can be controlled at display location and displays can be controlled at matrix location.
This is accomplished by placing a series of IR Emitters on devices to control and IR receiver at all
locations you wish to control from to enable the IR signal to travel both ways via the single
Cat5e/6/7cable.
1. At Matrix End: Inset the 3.5mm jacks of the IR TX Emitters included in package into the IR TX
Emitter ports at the rear of the matrix corresponding input. The IR signal is added to the HDMI
of the input devices, for example, if the user is watching Blue-ray on input 1, the IR signal will
be directed through the IR TX1 socket to control the device. As each IR TX port is allocated to
an individual HDMI input port, if the user is unable to control device via IR, please check if the
IR emitter and HDMI input ports match or not (Input1-TX1, Input2-TX2 etc.), and secondly, that
the IR TX emitter sensors are firmly attached directly to the front of inputs and covering
infrared sensor windows of the source devices. Some later adjustment may be needed to the
location of the sensor to achieve the best performance - sometimes moving the sensor to
different areas on the source can improve IR performance.
Note: Infrared receiving areas of devices can be located by shining a flashlight onto the front
of the device – the sensor should be able to be seen through the plastic as a small, round
object inside. Insert 3.5mm jacks of IR RX receivers into RX ports, making sure the receivers
themselves are placed in clear view to receive an infrared signal from the remote handset
used to control the display outputs.
2. At Display End: Insert the IR RX Receiver jack into the IR RX port of the display receiver balun,
with the receivers themselves placed in clear view on or near the displays to receive an infrared
signal from the remote handset used to control inputs. Insert the IR TX Emitter jack into the IR
TX port of the display receiver balun, ensuring that the emitter sensor is securely attached to
infrared sensor window of the display. Follow the same connection and position for all
baluns/displays connected to the matrix.
Note: Misplaced or poorly secured IR Emitters and Receivers may result in intermittent IR
control signals passed to and from the matrix. Check your placement and adjust if necessary.

Communication Code Configuration
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
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

Purelink’s HTX III-4400 User Manual V1.1
19
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 interested 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 -
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. For example,
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!
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.

Purelink’s HTX III-4400 User Manual V1.1
20
 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.
o (Ex., *999CI01O01,02,03! ↩ : Connects Input 01 to Output 01, 02, and 03)
 Use - (Hyphen) for range connection.
o (EX., *999CI01O01-04! ↩ : Connects Input 01 to Output 01,02,03, and 04)
