Continuous Pumping Mode
The continuous pumping mode eliminates the problem of flow rate drop-off that is typical with
continuous syringe pump systems, where one pump is refilling the syringe, while the other infuses, and
then they switch directions.
In this system, the refilling pump refills at a faster rate than the infusing pump, giving it time to
prime the syringe, then it pauses and waits for the infusing pump to empty.
Then, when the pumps switch directions, the refilled pump is primed and starts infusing at the set rate
immediately. Additionally, an overlap can be set, whereby the refilled syringe begins infusing before the infusing
pump is completely empty.
Requirements
2 Pumps from the NE-1000X family of syringe pumps. Pumps can be different models.
1 dual pump cable, part #CBL-DUAL-3.
Set communications mode to Continuous Mode [Cont]
On the Master Pump only: In setup, when the network address is displayed [Ad: 00], or other address mode, press
the left-most up arrow key to select [Cont].
Note: Don’t change the default settings on the second pump: Address 0 [AD:00] and 19,200 baud rate [1920]
Set Pumping Parameters on the Master Pump
Set syringe diameter and pumping parameters on the Master pump. The syringe diameter and pumping
parameters are transmitted to the second pump when the Master pump starts. Both syringes start empty.
Pumping Parameters
Phase # Function Rate Volume
1 RATE Infusion Syringe
2 RATE Refill Overlap Optional parameters
3 RATE Prime Prime Optional parameters
Set any optional parameter to 0.000 (off) if not used, or set the function to STOP. Pumping rates not set will
default to the Infusion Pumping Rate.
Hardware Setup
Attach the cable, CBL-DUAL-3, to the “To Computer” connector on the back of both pumps.
