Matrix 6400 Audio Switcher 3 Chapter Three Using the Matrix 3200/6400 System Virtualization/Control Software
Control Software, cont’d Control Software Tutorial - Using the Matrix 3200/6400 System Virtualization/Control Software Extron’s Matrix 3200/6400 System Virtualization/Control Program The Matrix 3200/6400 System Virtualization/Control program communicates with the Extron Matrix 3200/6400 System through the RS-232/422 port on BME #0 (defaults to 9600 baud, 8 bit, 1 stop, no parity). The program is required to initially set the Virtualization and optional Room configurations for the system.
output signals. Again, traditional hardware does this by causing the paired signals to follow each other, either in a single box that is made only for S-Video or by using two boxes designed for Composite Video and forcing them to follow each other by switching to the same input (or output) number.
Control Software, cont’d FIGURE 3-2.A • The program will communicate with the Matrix 3200/6400 System to determine its hardware configuration (type and size of each connected BME). It then reads the system’s settings (Ties, Presets, Virtual Map, etc.) and draws a graphical representation of the unit’s configuration and settings (Ties) on the Main screen (Figure 3-5.A & B). It also reads the MTRX6400.
Figure 3-4.A Figure 3-4.
Control Software, cont’d Figure 3-5.A Main Screen - Ties Figure 3-5.
RRRRGG..BBB). You may also change the ordering of the planes with this screen and affect which physical connectors get which signals. For example, in a Wideband system, instead of being in RGB order, you can change it to BGR order by using the radio buttons in each plane’s choices. Note that you may play with the settings in this screen without causing any changes to the system’s map until you press the ‘OK’ button.
Control Software, cont’d • Ensure that the System has been Virtualized before creating any Rooms. Establish an RS-232 connection between the PC and BME #0 of the Matrix 3200/6400 System. Start the MTRX6400 program (under Windows) and click on the corresponding COMM PORT number when asked (Figure 3-6.A). Click OK, or...... If you wish to program a FIGURE 3-6.A system without being connected to it at this time, click on EMULATE. Follow steps in How to Off-Line (Emulate) Program the Matrix.
How to Remotely CONTROL and PROGRAM the Matrix 3200/6400 System Because the Matrix 3200/6400 Switchers store their settings in a nonvolatile memory, programming applied to the unit from the Virtualization/Control Program (or the FPC) is remembered in the unit. The Program only needs to talk to the Matrix system long enough to create (program) the settings. You can, however, leave a computer connected (dedicated) to the Matrix for real-time interactive control and monitoring if you wish.
Control Software, cont’d • If you have edited any of the configurations or assigned Icons or Captions, when you exit the program you will be prompted to save the changes. These will be written to the MTRX6400.INI file for use in your next editing session (if you agree). The information in the file also allows you to fully restore a Matrix 3200/6400 System to all the settings (Ties, Presets, etc.) from the current session.
Ports are Grouped and Titled. Selecting a Preset (if any exist) from the Presets List at the right side of the screen will cause that configuration to be read from the emulated Matrix and drawn on the screen. The displayed preset becomes the “Current configuration” by clicking the GO BUTTON. • You can Add and Erase ties (edit) when in the “Current configuration”. These edits are made using the mouse in a drag and drop operation.
Control Software, cont’d How to Create PROGRAM BYTE STRINGS for the Matrix 3200/ 6400 System The Matrix 3200/6400 System can be controlled and programmed through the RS-232 port via third party control systems. These systems need to be “told” what bytes to send to the Matrix to perform this control.

Matrix 6400 Audio BME Internal Access Upgrades or repairs may require access to internal areas of the Matrix 6400 Audio BME. This involves removing the front access panel (blank or FPC-1000) using a coin or a flat blade screwdriver to rotate the two captive screws (Figure 5-2.A) as shown in Figure 5-2.B. Pull the top of the access panel out slightly then lift up and remove it from the front panel. The FPC-1000 will have a cable connecting it to the Main Controller, unplug the connector.
Upgrades and Troubleshooting, cont’d Installing A Software Update To install a software update, IC U9 or U6 (or both) on the Main Control printed circuit card is replaced. If the system consists of multiple BMEs, the software IC(s) in each BME’s Main Control PCB may need to be updated. Use the following procedure to replace the Matrix 6400 Audio Main Control PCB IC(s). 1. Power the system OFF and unplug the AC power cord. 2. Remove the Access Panel. See Page 5-3. 3. Use the PLCC IC puller (Figure 5-3.
Swapping BME #0 RS-232 / RS-422 Ports Swapping BME #0 RS-232/RS-422 ports (not required on BME #1 - BME #5) involves moving a ribbon cable from one Main Control card connector to another. Ribbon Cable Connectors The ribbon cables used in the Matrix 6400 Audio Switcher use a self-latching style receptacle. Figure 5-4.A shows how it operates. 1. Press each of the two tabs outward, this unlocks the receptacle and ejects the ribbon cable connector part way.
Upgrades and Troubleshooting, cont’d Troubleshooting a Matrix 3200/6400 System Problem All Matrix 3200/6400 BME front panels include LEDs at the bottom of the panel which are bracketed and labeled DIAGNOSTICS. These LEDs (Figure 5-6.A) indicate the current status of the BME power supplies, the RS232/BME/MKP1 Communications RX and TX lines, and the System Status. The following descriptions include normal/failure/status conditions for each LED.

Pry the fuse-holder out, it contains the AC input fuse plus a spare. If may be obvious that the fuse is blown, if not, check it with an ohmmeter or any other continuity device if available. If the fuse is blown, replace it with the provided spare. Plug the AC power cord in and Power the BME ON. Verify that the unit powered ON correctly (check Front Panel LEDs).
Upgrades and Troubleshooting, cont’d Matrix 6400 Audio Switcher Upgrade - Changing the Matrix Size Changing the matrix size of a Matrix 6400 Audio Switcher may require adding or removing input and/or output audio circuit cards. Page 5-9 describes the procedure for determining the required number of input and output cards for the desired matrix size and which connectors the cards should be plugged into. The following procedure describes how to change the matrix size. 1.

Upgrades and Troubleshooting, cont’d Changing the Audio Output Card Gain Jumpers The gain indicated by an FPC 1000 LCD panel or a Host computer running Extron’s Matrix 6400 System Control software may be off by 6dB depending on the type of output (balanced or unbalanced) and jumper positions on the Audio Output card. If the Audio card jumpers for each output are set to match the output type, the indicated gain will match the actual gain for all outputs.
change the gain for output 51, pull the card for outputs 49-56, count from the top header pair which is for output 49. The target headers are H13 and H14; swapping their jumper positions will change the gain for output 51. Gain jumpers must be changed in pairs (H9 & H10 through H23 & H24). Do NOT change the position of the jumpers on headers 25 and 26 (H25 & H26).
Upgrades and Troubleshooting, cont’d cabinet. There are no restrictions to the order in which BMEs may be mounted relative to each other. Logically, the BME addresses in a system such as the one shown in Figure 5-10.A would be set to 0 - 5 sequentially from top to bottom, however, a different order is acceptable and will not impact system operation in any way. Equipment location within a room should be given careful consideration.
5. • The current MATRIX settings will be saved in the MTRX6400.INI file. • The Matrix 6400 Control Pgm will shut down to allow you to power down the system to make the hardware changes. Return to step 2 of the applicable procedure (Page 5-8 or 5-11). Note: The “After Hardware Changes” procedure begins on Page 5-13. After Hardware Changes Do the following steps AFTER the hardware upgrade has been installed: 1. From Windows open the Program Group or Folder called “Extron Electronics”. 2.
