Model R100-EC

Combines the features of the R100-E with the precision of a computer controlled USB interface and API software. Includes all necessary pump drivers and a test program to verify proper USB installation and pump operation. The CD also includes files and information necessary to use the API (Windows dynamic load library type file) with Visual Basic, C, or MED-PC®.

Note: Any program that can call a DLL can use the API to control the R100-EC.

Razel® API Software:

  • Controls up to 16 pumps.
  • Each pump reads its own ID from the switch settings on power up making it easy to change pumps without setting internal jumpers, swapping cables, or changing computer connections.
    • Commands include:
    • Simple On, Off, and Reverse commands sends that data with the command once, the pump does not rest.
    • Pump starts and stops after an exact dose is delivered using the Dose command.
    • Two Ramp commands available allowing you to continue to run or stop the pump at the end of the ramp time.
    • Read Status command returns extensive diagnostic data including a high resolution pump travel counter and a 20 millisecond timer counter.
    • Reset command clears the timer and travel counters.
    • Set Alarm command permanently sets Loud or Low volume and the limit switch alarm repeat rate.
  • Executes the Dose and Ramp commands using it’s own internal timing. The PC is not burdened with strict timing functions.
  • API error status indicates success, pump data out of range, or pump not connected eliminating trial and error checking when an error occurs.

Also includes R-Option-F and R-Option-B.
