You simply point the pen at the desired channelLED and press the button on the barrel.Figure 3-3A shows how the light pen plugs into the frontpanel, and Figure 3-3B shows how the light pen is used.When an LED is clicked, it blinks for a couple of secondsand then assumes the appropriate state.Control LEDs are also provided to perform other operationsusing the light pen. Most of these LEDs simply perform thesame operations as their front panel key counterparts. Figure3-1 summarizes the operations of all the control LEDs.There are two basic display modes; the relay status displaymode and the list display mode. In the relay status displaymode (see Figure 3-4), the channel LEDs provide the open/close status of the available channels. This is the displaymode you want to be in when closing/opening channels orscanning so that you can observe the real-time state of eachswitch in your system.In a list display mode (see Figure 3-5), the channel LEDs indicatewhich channels are included in the list (channel list orscan list). Figure 3-6 provides an example of channel statusfor the two display modes. If you create a list while in thisdisplay mode, be sure to toggle back to the relay status displaymode before closing/opening channels or scanning.3-3
