8.3.14 'ES:nn': Setup Event Square Wave Trigger Jump Phase
nn
The 'Event Square Wave' function operates the same as the 'ET' 'Event' function, with the
exception of the triggering conditions.
This function will trigger on either the rising or the falling edge of the TTL 'Event Trigger' input (pin 4).
Therefore, a square wave function on the inupt pin can be used to toggle the pump between 2 sections of a
Pumping Program. An example of this would be a Pumping Program that switched between a slow and
fast pumping rate, controlled by a square wave input.
8.3.15 Event Reset
’Event Reset’ cancels a previously set event trap.
8.3.16 Set TTL Output Pin
n
Set ‘Program Output’ TTL I/O output (pin 5) to level ‘n’. If ‘n’ = 0, the output pin will be
set low. If ‘n’ = 1, the output pin will be set high.
8.3.17 Beep
Sounds a short beep.
