. . . . . . . . . . . . . . . . . . . . . . . . . . . . .EDID CONTROL

EDID, extended display identification data, is information which enables a graphics adapter source to output a graphics standard best suited for the connected display monitor. This information includes the display resolution and frame rate. Linx Switcher supports EDID management providing a choice of what EDID to supply to the source and arbitrates when an input is routed to multiple output ports connected to displays of differing capabilities.

Figure 1-3 Selecting EDID

. . . . . . . . . EDID REGISTERS There are three EDID registers within the Linx Switcher:• Display EDID - Contains EDID for each output passed through

from the display device. The contents of the display register may be saved as an entry in the EDID list.

• Emulated EDID - Contains EDID for each output selected from the EDID list.

• Fixed EDID - Contains fixed EDID for each input selected from the EDID list.

The factory default resolution for each register is 1280 x 1024 at a frame rate of 60 Hz.

. . .

. .

The block diagram in Figure 1-3 illustrates the selection of EDID to be passed to the host graphics adapter. The data is stored in the EDID interface which can be read when the Linx Switcher is powered on or off.

. . . . . . . . . HOT PLUG EVENT When a display is connected to an output port, a hot plug event occurs and the Linx Switcher downloads the display EDID parameters to the display EDID register.

A hot plug event also occurs when a graphics source, host, is connected to a Linx Switcher input port. A host can read the EDID interface when the Linx Switcher is powered off.

. . . . . . . . . EDID PRIORITY When an input is routed to multiple outputs, a number of options are available. Fixed EDID can be selected from the EDID list or a priority scheme used to select EDID from one of the output ports. Priority can be set to select the active output with the lowest resolution or the lowest numbered active output. EDID priority is applied to emulated and display pass-through data.

Only active outputs are considered when establishing priority. Active outputs are those having parameters stored in the Linx Switcher EDID display register; these may be outputs currently connected or those with assigned emulated EDID.

. . . . . . . . . EDID LIST The EDID list is used to apply parameters to the fixed and emulated EDID registers. Entries in the list are numbered 1 to 100. Data contained in the list include:

• List index number• Name• Display device manufacturer’s ID• Resolution and frame rate

Advanced users may view and modify additional timing parameters with third-party software such as Phoenix EDID Designer freeware available at http://www.tucows.com/preview/329441.

. . . . . . . . . EDID MANAGEMENT EDID management may be performed through the WCP or command line operation. EDID management is discussed in the Web Control Panel Operation and Command Line Operation sections of this chapter and in Chapter 4 . Management functions include:

• Loading EDID from the EDID list to a register• Saving display EDID to the EDID list• Naming an EDID list entry• Viewing an entry in the EDID list• Deleting an EDID list entry• Exporting and importing an EDID list entry

I N T R O D U C T I O N A N D I N S TA L L A T I O NInput Equalization


. . .

. .

. . . . . . . . . . . . . . . . . . . . . . . . . . . . .INPUT EQUALIZATION Input equalization is used to compensate for the losses caused by the electrical and physical characteristics of a DVI cable. The longer the cable, the greater the need for equalization.

Input equalization is used to compensate for losses based on input cable length. A non-equalized input may result in one of the following on the displayed output:

• “Sparkles”• Drop-out• No signal

Equalization for an input can be set to OFF, AUTO, or to a level between 1 and 50. Enter a level value if the default setting, AUTO, does not yield quality output.

No equalization should be needed for cables under 5 meters (15 feet) in length or for fiber optic cables. For longer cables, set the manual equalization level to a value that corresponds to the length, in meters, of the cable. Each cable is unique relative to the amount of equalization it may require. Tune equalization by entering higher or lower levels to reach the final setting.

The input equalization command, INputEQualizer, is described on page 36; input equalization is not available on the front panel or WCP.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . .INSTALLATION

. . . . . . . . . RACK MOUNTING If the Linx Switcher is to be rack mounted, it should be done before making any cable connections. Use screws compatible with the rack to secure the front of the unit.

VIDEO INPUTS AND

. . . . . . . . . OUTPUTSThe quality of DVI cables is important to the performance when long lengths are use. Cable using 24 AWG conductors may provide good results up to 50 meters. Cable equalization is only available on input channels so operation with 50-meter output cables will require an external equalizer.

CONTROL

. . . . . . . . . CONNECTIONSUse of all the Linx Switcher commands and function requires connection through the RS-232 or 10/100 BASE-T port.

R S - 2 3 2 C O N T R O L

Connect the Linx Switcher RS-232 to a PC using a cable with standard RJ-11 connectors.

I N T R O D U C T I O N A N D I N S TA L L A T I O NInstallation


. . .

. .

1 0 / 1 0 0 B A S E - T C O N T R O L

Connection to the 10/100 BASE-T port uses cables with RJ-45 connectors.

• Direct connection — Use an Ethernet crossover cable.

• LAN connection — Use a standard Ethernet cable.

. . . . . . . . . POWER Connect the Linx Switcher to a power source using the supplied cord.

Note Computers that are set up to communicate on the network are typically configured to have a dynamic IP address. In this configuration, the computer is provided with a suitable IP address by a network DHCP server. When connecting directly to the Linx Switcher a server will not be available; a static IP address must be set manually on the computer. Refer to the Setting the PC IP Address on page 10.

Note The Linx Switcher is configured at the factory with the default IP address 192.168.1.200. Before connecting to a network, verify that this is a valid IP address on the network.

CHANGING THE LINX DVI 8X8

. . . . . . . . . . . . . . . . . . . . . . . . . . . . .MATRIX SWITCHER IP ADDRESS

With a Hyperterminal or Telnet session initiated, use the following steps to change the Linx Switcher IP address to one compatible with the local area network.

1. To change the current IP address, type IPADDR followed by the new IP Address provided by the network administrator.

Example: If the new IP address is 192.168.1.190, type:IPADDR 192.168.1.190

... and press ENTER.

The Linx Switcher responds with the following message:The system must be restarted for your changes to take effect.

Do you want to restart the system (y/n)?

2. Type y to accept the new address, or n to retain the current address.

If y is pressed in the step above, the Linx Switcher reboots and the Telnet connection is lost.

3. To re-establish the Telnet connection, press ENTER to display the command prompt. Type telnet 8000 using the new IP address.

In addition to setting the IP address, the IP subnet mask (IPSubNET) and gateway (IPGateWay) can also be set as required. This completes the procedure for setting up the IP address.The Linx Switcher can now be connected to a LAN for control over the Ethernet port using ASCII commands from the Telnet Window or from the Web Control Panel using a standard web browser.

Important When the IP address is set from the Ethernet port, the Telnet connection (and communication) will be lost. This behavior is to be expected. Restart the Telnet session using the new IP address.

Note To close a Telnet session, type EXIT and press ENTER or use the keystroke sequence Control + D.

Table 6-1 Troubleshooting Guide

Problem Symptom Action

Power No AC power.

Check that the power cord is correctly connected to the Linx Switcher and to an AC power source and that the power switch is in the ON position.

If an output from a graphics adapter is connected to a Linx Switcher output while power is off, the switcher will not power on. Check the output connections.

Telnet

Invalid password. Correct password is RGB; this must be upper case.

User name and password entered but connection to host is lost.

8000 must be entered following the IP address in the telnet command.Example:

telnet 192.168.34.70 8000

Cannot connect to host.Check that the PC has a static IP address compatible with the Linx Switcher and network.

Output No output present.

Output has been disabled. Use OUTputENable to display or change an output status.

The display is not capable of the resolution sent to it. Set the output display mode to pass-through and the EDID mode of the input to dynamic.When a single input is routed to multiple outputs, EDID priority may not yield compatible resolution. Set EDID priority to minimum resolution.When EDID priority is set to lowest output number, the output with the most universal EDID should be connected to the lowest output port.If the EDID works for some displays, try setting the display mode to emulate for all the outputs in the group.

The souce has stopped sending a signal. Check that the input status box at the bottom of the WCP routing window is green or use the INputSTATus command.
