8.4.8 Example 8: Dispensing with Complex Synchronization
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 SP1600/SP1800.
The Pumping Program begins by canceling any previous event traps (PH:01) and raising the ‘Program
Output’ TTL line (PH:02). After 5.0 ml has been dispensed at 800 ml/hr (PH:03), the ‘Program Output’
TTL line is lowered (PH:04), sending a synchronization signal to another device.
The pump then continues to pump at 800 ml/hr (PH:06) until a synchronization signal is received at the
‘Event Trigger’ TTL input, causing the Program to jump to Phase 7 (PH:05).
The pump then withdraws 0.25 ml (PH:07), pauses for 1 second (PH:08), then repeats this process if the
Program Input TTL line is low (PH:09), otherwise it continues with the next Phase.
Next, the pump pauses for 10 seconds (PH:10). Then it pauses again for the lesser of another 10 seconds
(PH:12) or until an Event Trigger occurs (PH:11). The Program then restarts (PH:13).
