LSP02(10)-1B Syringe Pump RS485 setup (Release Time：2017-01-06)

 The RS485 connections are made through terminal connectors, located on the rear panel. A single PC can control up to 30 pumps. When controlled by a PC each pump must be assigned an individual address. When controlled via RS485 the pump will still respond to keypad commands. All RS485 commands settings, similar to keypad settings, are stored in EEPROM. When RS485 is enabled, RS485 interface will display communication address and band rate.

The communication address is from 1 to 30. The default address is 1. The band rate is 1200 bps, 2400 bps and 9600 bps. The default band rate is 2400 bps.

RS485 format: 1 start bit, 8 data bits, 1 even parity, 1 stop. For detailed RS485 commands please see <Longer’s RS485 Protocol for LSP>.

In parameters setting interface, press and turn RES to highlight the RS485 line. Set RS485 enabled. The LCD displays communication address and band rate. Turn RES to make the address highlighted. Press RES to highlight the numerical value. Turn RES to set the communication address. Press RES again to confirm and save the setting. Turn RES to highlight the band rate.  Press RES to make the numerical value highlighted. Turn RES to select the band rate. Press RES again to confirm and save the selection.

LSP02(10)-1B Syringe Pump External control function (Release Time：2017-01-06)

External control function, including run/stop control input and direction control input can be enabled or disabled.

1. In parameters setting interface, press and turn RES to highlight the external control line.
2. Press RES to highlight the parameter. Turn RES to select the needed parameter.
Disable: disable the external control input, that is, the input is invalid.
TTL: TTL input controls the start and stop of the pump.
Trigger: falling edge input controls the start and stop of the pump.

LSP02(10)-1B Syringe Pump Calibration (Release Time：2017-01-06)

The flowrate can be calibrated for more accurate dispense volume.

1. In parameters setting interface, press and turn RES to highlight the Calibration line. Press RES to enter calibration interface.
2. Testing time line is highlighted. Press RES to highlight the numerical value position. Turn RES to select the testing time. The testing time is from 0.5 minutes to 60 hours. Press RES to confirm.
3. Press Run/Pause key to start the testing. After testing, turn RES to highlight the testing volume line. Press RES to highlight the numerical value position. Enter the actual volume from the membrane keypad. Press RES to confirm.
4. After calibration, the linear speed of the Pusher Block changes to increase the accuracy of the dispense volume.

LSP02(10)-1B Dual Channels Syringe Pump Pause time setting (Release Time：2017-01-06)

In infusion/withdrawal mode, the pause time is set in infusion parameters setting interface. In withdrawal mode, the pause time is set in withdrawal parameters setting interface. In continuous mode, the pause time need to be set both in infusion mode interface and in withdrawal mode interface. The unit of pause time is sec, i.e. second, and the range of pause time is from 0 to 9999sec in steps of 0.1sec

LSP02(10)-1B Dual Channels Syringe Pump Flowrate setting (Release Time：2017-01-06)

In parameters setting interface, turn and press RES to highlight the infusion flowrate or withdrawal flowrate setting line. Press RES to make the numerical value position highlighted. Enter the flowrate required from the membrane keypad. Press RES to set flowrate unit. Turn RES to scroll through the list and press RES to select the unit required. Possible flowrate units are µl /h, µl/m, ml/h, ml/m. The highlighted display indicates that this parameter can be changed.

Note: If the number entered exceeds the maximum flowrate possible then the pump prompts the maximum feasible flowrate at the Time position. To continue enter a flowrate smaller than the maximum.

LSP02(10)-1B Dual Channels Syringe Pump Volume setting (Release Time：2017-01-06)

In parameters setting interface, turn and press RES to highlight the infusion volume or withdrawal volume setting line. Press RES to make the numerical value position highlighted. Enter targeted volume from the membrane keypad. Press RES to set volume unit. Turn RES to scroll through the list and press RES to select the unit required. Possible volume units are µl and ml, i.e. microliter and milliliter. The highlighted display indicates that this parameter can be changed.

Note: When the volume setting is zero, Infusion or Withdrawal modes.
Volume = 0 is interpreted as no volume and the pump will run until manually stopped or a stall occurs.
The LCD will display the flowrate setting. Infusion/withdrawal, Withdrawal/infusion and Continuous modes.
A volume setting must be entered. If no volume is entered the motor does not run.
