The following is an example of a GW basic program used to control from 1 to 16 DA-3212s.
The factory preset is machine #1, whose command is on line 910. The first group of
characters are used to determine which machine number is being activated in a multi
switcher system. Normally machine #1 is used a default. The second group determines the
Input that will be switched to the output once the commands are sent. Line #905 represents
the settings for the RS-232 Com. port. If you have any questions please call Compu-Video
Systems at (845) 737-7009 between the hours of 9am and 5pm (EST).
