    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.

    Price: add $230 USD to any NE-8000 model

    Model: FW-1-X2

    Extra Features: X2 upgrade includes all features of the X firmware upgrade, plus increases the programming memory from 41 to 340 Phases.

    Pump Programming:

    • 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.
