Linux Driver Installation
This document describes how to enable communication between a Piccolo Xpress or VetScan VS2 analyzer and Linux. In this document you will install a driver that makes a Piccolo Xpress or VetScan VS2 analyzer available as a virtual communications port in Linux.
Installation requires the following:
§ Piccolo Xpress or VetScan VS2 Blood Chemistry Analyzer
§ PC with Linux (kernel version 2.6.9 and above)
§ PC with an available USB port
§ USB cable with Type A and Type B adapters (small and big ends).
§ Abaxis Driver CD or the file "Abaxis Driver CD.zip" (download from the Abaxis web site).
Note 1: The driver is already included in the Linux OS (kernel version 2.6.9 and above). The driver is also available on the Abaxis Driver CD in the Linux folder.
Note 2: Driver installation in Linux requires root account privileges.
Note 3: The screen shots in these instructions are from a typical Ubuntu Linux installation. Some of the dialog boxes shown may vary slightly in other versions of Linux.
Note 4: USB Cables are available from Abaxis Technical Support 1-800-822-2947.
Driver Installation
1. Turn ON the PC.
| |
2. Connect the large end of the USB cable (Type A connector) to the Linux computer.
|
![]() |
3. Connect the small end of the USB cable (Type B connector) to the Analyzer. |
|
4. Turn ON the analyzer. |
|
5. Open a Terminal window in Linux 6. Login as root. 7. Navigate to the directory /etc/udev/rules.d. 8. Create and open a file named 99-usbftdi.rules.
|
|
9. Type the following text into the file. # For Abaxis Blood Chemistry Analyzer with Vendor ID = 0x0403, Product ID = 0xcd18 SYSFS{idProduct}==”cd18”, SYSFS{idVendor}==”0403”, RUN+=”/sbin/modprobe –q ftdi_sio product=0xcd18 vendor=0x0403” 10. Save and close the file.
|
|
11. Terminal > Type sudo udevcontrol_reload rules > Enter. If the command udevcontrol_reload is not recognized restart the computer or use the commands: Terminal > Type stop udev > Enter. Terminal > Type start udev > Enter.
|
|
12. Confirm the USB Port is recognized as a Serial Port on the computer. Terminal > Type dmesg | grep FTDI > Enter. Identify the analyzer as FTDI USB Serial Device converter > Record the Communications Port where the Analyzer is installed (e.g. ttyUSB0).
|
|
13. Configure any PC applications (e.g. minicom or CuteCom) to communicate with the analyzer over the virtual communication port recorded in Step 12. CuteCom is configured with the parameters: Device ttyUSB0 (port recorded in step 12), Baud rate: 9600, Data bits: 8, Stop bits: 1, Parity: None.
Note: You may need to uninstall the "brltty" port before the USB to Serial driver will work in Ubuntu Linux. Terminal > Type sudo apt-get remove brltty > Enter. |
