Ethernet Web Interface

MuxLab offers users an Ethernet Web interface that provides the same functionality as manual control, with speeds of 10 Mbps or 100 Mbps.

To use the Ethernet Web interface, the Matrix Switch must first be physically connected to an Ethernet network. To do this, locate the RJ45 Ethernet jack on the back panel of the Matrix Switch, then connect it to an Ethernet network using a straight UTP cable (maximum length: 328 feet [100 meters]). There are two LEDs at the bottom of the RJ45 Ethernet jack: A green LED will go on if a link is detected, and a yellow LED will blink if Ethernet activity is detected.

Once the Matrix Switch has been physically connected to an Ethernet network, go to

http://AAA.BBB.CCC.DDD, where AAA.BBB.CCC.DDD is the device IP address.

(NOTE: The device IP address can be obtained by pressing the Info button on the front panel.)

The Login screen is the first screen to appear (Figure 18).

Figure 18: Ethernet Web Interface Login Screen

The default password for administrators is admin. The default password for regular users is user.

NOTE: Users who have previously logged in and chosen a password, but have subsequently forgotten it, may connect to the device using the RS232 or USB and reset their password using a terminal emulator.

Three items are presented to the user at the top right of every Ethernet Web interface screen:

• Logout option

• Language option

• Product status

Page 20

The Logout hyperlink logs the user out of the system. The Language drop-down list provides the user with three interface languages:

English, French, and Spanish. English is used by default. The Product status indicator provides a quick indication of device status by means of

a colored box (green, orange, red) to indicate various product statuses:

• Green = Okay

• Orange = Warning

• Red = Error

The user can configure the Product status indicator to display different statuses depending on various device conditions (internal temperature, fan speed, etc.). This configuration is performed in the Alarm tab of the Setup submenu.

After logging in, the main screen appears (Figure 19). It contains three submenus:

(1) Port Management (2) Setup (3) Help

(1) Port Management

The Port Management submenu (Figure 19) appears after the user has successfully logged in.

Figure 19: Port Management Submenu

The Port Management submenu manages the connection configurations of displays and sources.

A connection configuration is a specific set of mapping instructions between all displays and devices. A saved connection configuration is known as a preset.

Page 21

The Port Management submenu allows the user to make individual connections between specific displays and sources, or wholesale connections between all displays and sources by means of presets. Sources and displays are presented to the user in any one of four ways:

• By source name

• By source number

• By display name

• By display number

Figure 19 illustrates sources and displays presented by display number. The user can make changes to the connection configuration of the device by selecting any option in the drop-down boxes in the Source column. Once any change is made, the given row will change color to indicate that a change has taken place. Once all selections have been made, the user clicks on the Connect button to apply those selections.

Presets are pre-established connection configurations that are used to apply wholesale mapping instructions between all displays and sources (see Figure 20). The user can load any one of eight presets to the device. Once a preset is selected from the Preset drop-down menu, the user clicks on Load Preset to show the connection configuration of the given preset. To apply the preset, the user clicks on Make Connections.

To modify a given preset, its name must first appear in the Preset drop-down menu. The user then makes changes to the connections between displays and sources (any change will result in a highlighted row). Once all changes are made, the user clicks on Save Preset. This effectively modifies the connection configuration of the given preset.

Figure 20: Port Management Submenu – Presets

Page 22

(2) Setup

The Setup submenu (Figure 21) is used to perform the following tasks:

• Modify port names

• Modify present names

• Modify network connections and passwords

• Modify RS232 connections

B. IP Control Commands

1. Notice

This section is provided for informational purposes only, and should only be used by software developers with a thorough understanding of the HTTP and JSON specifications.

2. Introduction

The Matrix Switch can be controlled using basic IP commands. These commands are based on the JSON format and are sent and received in standard TCP/IP packets. To learn more about JSON, visit http://www.json.org.

Only four types of JSON arrays are used to control the product:

Array of a single integer: [2] Array of multiple integers: [1,2,3,4] Array of a single string: [“A Name”] Array of multiple strings: [“Name 1”, “Name 2”, “Name 3”, “Name 4”]

Any other notation is not permitted. Also, “null” values are not permitted. Use 0

instead.

3. Basic Usage

All read and write operations are performed via HTTP GET and HTTP POST commands, respectively. While you can perform a GET at any time, a POST command will require prior authentication.

4. Basic Authentication

Authentication is performed in two simple steps:

1. Obtain a Session ID

Perform a GET request on /var/session.json to obtain a new session ID. The return value will be a JSON array of a single integer, for example [12345]. From then on, simply append the session to any new IP requests to use this session, e.g., GET

/var/conn.json?sid=12345

2. Obtain Credentials for that Session ID

There are three permission levels that can be used to read/modify properties. These are:

0 – Guest: Can read all values. Cannot write or make changes. 1 – User: Same as Guest, but can change matrix video connections. 2 – Admin: Can perform any command without restriction.

To obtain credentials, you will need to POST an array of two strings to /var/auth.json: the userlevel, and the password associated to that user. For example:

POST /var/auth.json?sid=12345

POST data: [“2”, “mypassword”]

Page 41

4. Basic Authentication (Continued)

If successful, you will receive an HTTP 201 Created response. Sessions will automatically close after 5 minutes of inactivity. They may also be

closed at any time by a GET /var/logout.json.
