11.2 TTL I/O Control from the Pumping Program
Various Pumping Program functions can define how the pump reacts to levels on the TTL I/O connector or
set output levels. These are summarized in the following table:
Pumping
Program
Function
TTL I/O Control Pin Pin # Action
OUT.n Program Output 5 Set logic level output to ‘n’
EV:nn Event Trigger 4 Falling edge triggers a jump to Phase ‘nn’
ES:nn Event Square wave
Trigger
4 Rising or falling edge triggers a jump to Phase 'nn'
IF:
Programmab
le Syringe
Pump nn
Program Input 6 Low level causes a jump to Phase ‘nn’
PS:00 Operational Trigger 2 Trigger activation resumes Program operation
11.3 TTL I/O Control from RS-232
The logic levels of pins 2, 3, 4, and 6 can be queried from an attached computer using the RS-232 ‘IN’
command.
The output logic level of pin 5 can be set with the RS-232 ‘OUT’ command.
