• Square Wave: Active data is detected at the data input.
Please refer to the Video Output Mapping Menu described earlier for important notes
regarding channel mapping and instructions on how to enable mappings.
Main -> Local -> Data -> Format Select:
This menu allows the user to view and change the format for a specified data channel.
The first line of this menu shows the currently selected channel. The second line shows
the current data format. If the switch on the Data Module for the corresponding data
channel is set to position 0, then the data format can be modified. If the switch is set to
any other position then the format cannot be changed. The third line indicates the status
of a test pattern ("OFF" or "ON 1-0-Z"). The test pattern is generated at the specified
output channel, so an Input Data Module is not required and channel mappings will
have no affect on the test pattern.
Use "+" and "-" to change selections at each line in the menu. Press "left" to exit this
screen. When leaving this menu with test patterns enabled, a warning message comes
up alerting that test patterns have been disabled to allow real data to pass.
