This example demonstrates a complex interaction with external equipment, such as synchronizing with another
syringe pump. The Program includes a variety of interactions with external equipment, which demonstrates the
various control possibilities of the SP2200.
The Pumping Program begins by canceling any previous event traps (PHASE 01) and raising the ‘Program
Output’ TTL line (PHASE 02). After 5.0 ml has been dispensed at 800 ml/hr (PHASE 03), the ‘Program
Output’ TTL line is lowered (PHASE 04), sending a synchronization signal to another device.
The pump then continues to pump at 800 ml/hr (PHASE 06) until a synchronization signal is received at the
‘Event Trigger’ TTL input, causing the Program to jump to Phase 7 (PHASE 05).
The pump then withdraws 0.25 ml (PHASE 07), pauses for 1 second (PHASE 08), then repeats this process if
the Program Input TTL line is low (PHASE 09), otherwise it continues with the next Phase.
Next, the pump pauses for 10 seconds (PHASE 10). Then it pauses again for the lesser of another 10 seconds
(PHASE 12) or until an Event Trigger occurs (PHASE 11). The Program then restarts (PHASE 13).
