10.4.2 Automation Cable: Reciprocating Pumps Control Cable
Part #: CBL-TTL-1
Using two SP-1000 family syringe pumps, this cable creates an automated continuous operation pumping
system, whereby one pump is refilling while the other is dispensing.
This cable is attached to two SP-1000 family syringe pumps via their ‘TTL I/O’ connectors. In this setup,
with the pumps configured for this operation, one pump will infuse while the other pump withdraws.
When one pump changes direction the other pump changes direction. When one pump starts, the other
pump starts. When one pump stops, for any reason, the other pump stops.
