mands set up Model 2500 triggering as follows:
• Arm layer source: bus
• Arm layer count: 2
• Trigger layer delay: 0.1s
• Trigger layer count: 10
• Trigger layer output events: source and sense
• Trigger layer trigger link output line: 1
After the unit is set up, :INIT is sent to take the unit out of idle. *TRG is sent to trigger the

trigger the unit the second time, and it then completes the second cycle through the trigger
layer.
