Matrix 50 Series Switchers 4 Chapter Four Programmer’s Guide Host-to-Switcher Instructions Switcher-Initiated Messages Switcher Error Responses Using the Command/Response Table Command/Response Table
Programmer’s Guide, cont’d Programmer’s Guide The switcher’s rear panel RS-232/RS-422 connector (figure 4-1) can be connected to the serial port output of a host device such as a computer, RS-232 capable PDA, or control system. This connection makes software control of the switcher possible.
The switcher does not expect a response from the host, but, for example, the host program might request a new status. Switcher Error Responses When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host.
Programmer’s Guide, cont’d Command/Response Table Symbol Definitions: = Carriage return/line feed = Carriage return (no line feed) • = space Input and output numbers in commands may be entered as either 1-digit or 2-digit numbers. All input and output numbers are specified as 2-digit numbers in the response.

Matrix 50 Series Switchers 5 Chapter Five Matrix Software Matrix Switcher+ Control Program Button-Label Generator
Matrix Software, cont’d Matrix Software Two software programs accompany the Matrix 50 Series switchers: • The Extron Matrix Switchers Control Program (Extron part number 29-015-01), which communicates with the switcher via the RS-232/RS-422 port, provides an easy way for you to set up ties and sets of ties. If your Matrix 50 Series switcher was previously set up for RS-232, and your computer comm port uses RS-422, you must change the switcher cabling to match the computer interface.
4. To make the control program easier to use, you can assign a device icon to each input and output. Click on a box that represents an input or output, and drag the desired icon onto the box from the icon palette that appears. 5. To create a tie, drag an input box to one or more output boxes. To remove a tie, drag the output box to its tied input box.
Matrix Software, cont’d Go — Activates the selected preset as the current configuration. Save as — Allows the current set of ties to be saved as a preset. Enter the preset number when prompted to do so. Changes – Take — Allows you to save to file any changes made to the displayed configuration. Changes – Cancel — Returns to the previous screen, undoing any changes you have made.
