If multi-channel modules, or several single channel modules, are installed on the PCI bus, multiple waveform 
displays, one from each installed channel, are overlaid on the display. 

The current channel is selected by clicking on the channel name within the upper portion of the control panel. The 
vertical settings of the current channel and the timebase and trigger of the correspondent digitizer are then indicated. 
A unique name is given to each channel installed on the PCI bus. The current channel is indicated by a dark highlight 
over the name. Settings changed on the main control panel will only affect the active channel. Always verify proper 
acquisition setting for each channel prior to collecting data. 

There is a small rectangular indicator button to the left of each channel name in the channel list. If this indicator is 
filled in, the channel waveform is active; the channel is turned on and displayed in the display window. Clicking on 
this indicator once turns it transparent. This deactivates the reading of the data from the channel and clears the 
waveform display. Clicking once again on the indicator turns the channel back on and the indicator is filled in. After 
making such changes the channel data will not be displayed until after the next acquisition. 

The image at the left shows a channel list with four active channels 
in the system. All are turned on and displayed in the display 
window as indicated by the black indicators at the left. The DC271 
Ch1 is the currently selected channel. 

The channel list image at the right shows the same system with the DC271 Ch2 
selected as the current channel. The other indicators are transparent and therefore 
their channels are turned off and not displayed.
