”Next Generation” Continuous Pumping Mode
(‘X Firmware Version Only )
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 series 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: Do not change the default settings on the second pump: Address 0 [Ad:00] and 19,200
baud rate [1920]. If unsure, reset the secondary pump: While turning on power, hold the left-
most up arrow button. The display will show [rESt].
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, unless pre-filled syringes are specified.
