NOTE: A list of characters supported by the MDA for display of message text is provided in Appendix B.
NOTE: Positioning the title/ time/date text in the top or middle of the screen in the Position Text dialog box ensures that you will be able to view the message text that is displayed on a moni- tor. (For information about the Position Text dialog box, refer to the Set Display section of this manual.)
SET MESSAGE TEXT
The CM9760-MDA accepts message text to meet the needs of applications that require real-time information overlaid on the video being viewed. Up to five lines of message text can be sent to the MDA simultaneously. Each line can contain up to 24 alphanumeric characters. The message text can be inserted onto any MDA channel independently.
The CM9760-MDA Setup program provides a tool that demonstrates support of the message text feature of the MDA. The program allows message text to be sent from the PC to an MDA or to an MDA daisy chain. The PC application is designed as an example of message text operation for third parties who wish to develop their own message text interface to the MDA. (Refer to the Applications section of this manual for an application diagram and to Appendix C for a listing of the message text insertion commands supported by the MDA.)
To set message text using the CM9760-MDA Setup program, proceed as follows:
1.Open the Position Text dialog box and do the following:
a.Position the title/time/date text in the top or middle of the screen (the text should not be positioned at the bottom of the screen).
b.Close the Position Text dialog box.
2.Open the Message Text Editing dialog box by clicking Edit on the CM9760-MDA SETUP dialog box and then clicking Message Text. The Message Text Editing dialog box, Figure 31, appears.

4.Enter the channel (camera) number (1-16) for which you want to set message text, and then press Return. Note that all subsequent changes using the CM9760-MDA Setup program will be applied to the channel number that was entered.
