New Era SyringeTwo (NE-4000) Programmable Two Syringe Pump
The NE-4000 produces about 15 lbs (7.5 lbs/syringe) of linear force at top speed and about 100 lbs (50 lbs/syringe) at slow speeds. 10 mL/hr is an example of slow speed. The pressure that can be generated is relative to the syringe size. On a 60 mL syringe, this would roughly produce about 30 psi.

- One-click program upload from "Pumping Program Generator" spreadsheet
- Up to 340 programmable phases
- Enter programs from the keypad or from a computer.
- Download or upload pumping programs from or to a computer. Store dispensing programs in a file on your computer, then upload them to one or more pumps. Specify in the file to send a different pumping program to each pump in the pump network.
- Pre-program dispense volumes. Each volume can be different.
- Automatically change pumping rates or pumping direction.
- Ramp up or down the pumping rate.
- Set timed delays between dispenses.
- Automatically pause the program and wait for the user to continue the dispense.
- Synchronize dispenses with other equipment or pumps to change pumping rates in reaction to a sensor or signals from other pumps.
- Send logic signals to other equipment. Change pumping rates in reaction to a sensor.
- Program the audible alarm to beep at any time to alert the operator.
Bi-Directional RS-232 Interface
- Network up to 100 pumps from a single communications port on a computer. Baud rates up to 19200.
- Free terminal emulator program allows communications with syringe pump.
- Directly control one or more pumps from a computer, including setting the pumping rate, direction and volume. Set the operational and setup configurations. Also the TTL interface can be queried and the programmable output set.
- Using a computer, each pump in the pump network can be individually controlled and monitored. Or, the computer can download a new pumping program to each pump which would automatically reconfigure the dispensing system for a new job.
- Downloading control programs to the pump would unload computer overhead to the pump. computer resources could then be used elsewhere while the pumps operate independently.
- 2 modes of communications: Basic and Safe
- Basic: Basic master-slave interface. Easy to implement. Can communicate from any terminal emulator.
- Safe: A reliable interface for a real-world environment.
- High quality interface which detects communication errors via a 16 bit CCITT CRC.
- The pump will automatically transmit an alarm packet when a pump alarm occurs. For instance, if the pump stalls or resets, a message is immediately sent to the computer.
- A configurable communications time-out will stop the pump and alarm if the communications link is broken.
- Packet inter-character time-out to recover packet synchronization after communication glitches.
- Software Developer friendly communications protocol.
- Consistent and well defined communications packets.
- Constant start and end characters.
- Packets structured to be easily parsed
TTL Logic Contol Interface
- Control the pump from a foot switch or timer.
- Output signals can be used to switch a valve from an output to an input reservoir.
- Keypad Lockout: Prevent unauthorized or accidental changes to the settings by requiring a "Lockout Disable" key to be inserted to change settings.
- Pumping direction control
- Programmable output signal
- Programmable responses to input signals
- Configurable start and stop trigger:
- Start or stop the pump on each contact closure to ground. For example, a foot switch.
- Start the pump on closure to ground and stop the pump on opening the connection. For example a timer relay that starts the pump whenever closed and stops the pump whenever open.
- Only start the pump on each contact closure to ground. For example, a laboratory animal trained to press a lever can receive a drug dosage from the pump and the pump will not stop or deliver another dosage until it is permitted by the pumping program entered by the user
- Configurable trigger input:
- Edge trigger: Starts or stops the pump, such as from a foot switch
- Level trigger: Start or stops the pump, such as from a timer or relay control
- Start only trigger: Edge trigger will only start the pump, such as from a lab animal trained to press a lever to receive a dosage.
