Introduction

“Extron MGP-641” Driver helps integrate Extron’s Multi-Window Processors with RTI control processors.

Driver Features

Supports 4 Input Windows and 2 Outputs.

Entering Admin “Password” is supported in this version of driver.

Can automatically detect & process authentication request from MGP-641.

Works even without Password authentication. When disabled in MGP-641.

Provides Integer, String & Boolean Variables for inputs, outputs & other parameter settings.

Provides Events for Important Feedbacks.

Can connect to MGP-641 on TCP/IP or RS232 port.

Polling for Status / Values:

Extron MGP-641 will not provide proactive (automatic) feedback when any parameter changes within the system. The current Status or Values of various parameters in MGP-641 can be obtained in following 2 ways.

Using Polling option provided in “Driver Settings”: This option will continually send status requests (that are selected under “Poll Requests” in Driver Settings) to MGP-641 & update variables at a frequency set in Poll Settings. Please note that this option will keep sending requests even when MGP-641 controlling in not active on any of the controllers. To avoid load on RTI processor and not overload the MGP-641 with continuous requests, it is strongly recommended that this option is used only when events are required & select the requests which are necessary. Please Note, when selecting several requests, ensure that the “Delay between Polling Cycles” is more than 3 seconds.

Using “Get Status” command(s) along with “Page Open” macros: You may request statuses / values for all the parameters that are programmed on current page. This option will poll for status only once when opening the page & that are required to be displayed on page. Using “Get Status” Functions are provided for all supported parameters. Further the status is updated whenever a command is sent. See “Extron MGP-641 Sample.apex” file on how to use this feature.

Prerequisites

Installation, Commissioning & Programming of Extron MGP-641.

Configure Static IP to use with TCP/IP connectivity.

Enable “Telnet” communication & assign suitable Port No. (23 Default) in MGP-641 using Extron’s VCS or any similar application.

Configure Baud Rate, etc. as necessary if RS232 connectivity is to be used.

Driver Configuration

Debug Settings:

Driver provides 3 Levels of Debug information for driver performance monitoring & troubleshooting. Select any or all options to get “Error”, “Warning” and/or “Info” debug messages as necessary in RTI’s “TraceViewer” debug console. Note: The option(s) are to be enabled only for reasons mentioned & shall be deselected during handover of project. Keeping this option(s) selected will consume extra Processor resources.

General & Connection Settings:

MGP-641 Name - Enter ‘Name’ to identify this MGP-641 in Debug Console.

Admin Password - Enter Password for Authentication. This is needed only when password is enabled in MGP-641.

Event Trigger - Here you can select the behaviour of how Events are triggered. Select either to trigger events only when the previous status is different from current status or trigger events whenever the status is reported.

Communication Type - Select either TCP/IP or RS232 to connect to MGP-641. Note: Telnet Option shall be enabled in Extron MGP-641 to use TCP/IP control.

IP AddressT - Enter IP address of MGP-641.

TCP/IP Port No.T - Enter TCP/IP port No. on which RTI processor will connect to MGP-641. Default port No. is 23.

Serial PortR - Select one of the unused RS232 ports of RTI processor.

Baud RateR - Select Baud Rate as configured in MGP-641. Default rate is 9600.

Max No. of Windows to use - Enter Maximum No. of Input Windows used. This provides ease of programming.

Poll Settings:

Enable Polling - Select this option if you wish to use continual polling for statuses. See 2.8.1 for details.

Delay between Poll Cycles - Enter the delay in seconds [between 2 to 30]. Note, this is not poll frequency but the delay between polling cycles. Selected poll requests are sent one after the other at a frequency allowed by Extron device, sending one complete set of requests is known as a cycle.

Poll Requests:

Select Requests that are to be added to polling list. All Selected requests will be sent to Extron device to get statuses. Select the requests that are really necessary. See 2.8.1 for further details.

Window Settings:

Use Window-x - Select, if window-x is active on Extron device.

Window-x Name - Enter Name to identify this window in programming.

Note:

Options 4.2.5 & 4.2.6 marked with (T) are available only when TCP/IP is selected at 4.2.4.

Similarly, options 4.2.7 & 4.2.8 marked with (R) are available only when RS232 is selected at 4.2.4.

X = Window No. between 1 ~ 4. Options like 4.5.1 & 4.5.2 will be available for each of the Windows as selected in 4.2.9.

Option to enter Name for Window (eg. 4.5.2) is available only when Use Window (eg. 4.5.1) of that particular Window is Selected.

Option availability to configure Use Window or Window Name depends on value of Max No. of Windows entered at 4.2.9.
