Pin 4 is used for the external trigger input and pin 
17 is used as the trigger output. Pin 5 is the 
common for both pins. 
The trigger input can be configured to perform an 
action such as toggling the output on/off, load a 
memory setting or apply a voltage/current setting 
when a trigger is received. The trigger input pulse 
width can also be configured. 
The trigger output can be configured to be active 
when the output is turned on/off, a setting is 
changed or when a memory setting has been 
recalled. The trigger output pulse width or level 
polarity can also be configured. 
See page 111 for details on the trigger input and 
trigger output configuration settings. 
The TRIG OUT signal is held 
high by an internal 330Ω 
resistor. The trigger output is 
pulsed or held high/low for 
each trigger (depending on 
the trigger configuration).
