Using the TS-9449

From Technologic Systems Manuals (sandbox)

The TS-9449 is autodetected by most recent operating systems using the FTDI serial to USB chipset. In Linux, this is the ftdi_sio driver. Upon inserting this to your workstation you can get the device name from dmesg. The dmesg output is chronological order so the last output should show the connection:

 usb 2-2.1: new full speed USB device using uhci_hcd and address 4
 usb 2-2.1: New USB device found, idVendor=0403, idProduct=6001
 usb 2-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
 usb 2-2.1: Product: FT232R USB UART
 usb 2-2.1: Manufacturer: FTDI
 usb 2-2.1: SerialNumber: A501BUBF
 usb 2-2.1: configuration #1 chosen from 1 choice
 USB Serial support registered for FTDI USB Serial Device
 ftdi_sio 2-2.1:1.0: FTDI USB Serial Device converter detected
 usb 2-2.1: Detected FT232RL
 usb 2-2.1: Number of endpoints 2
 usb 2-2.1: Endpoint 1 MaxPacketSize 64
 usb 2-2.1: Endpoint 2 MaxPacketSize 64
 usb 2-2.1: Setting MaxPacketSize 64
 usb 2-2.1: FTDI USB Serial Device converter now attached to ttyUSB1
 usbcore: registered new interface driver ftdi_sio
 ftdi_sio: v1.5.0:USB FTDI Serial Converters Driver

So in this case my device is "/dev/ttyUSB1". These are allocated numerically so if you do not have another usb serial device it may be "/dev/ttyUSB0". If you do not see this device you will need to see your distribution's support for adding the ftdi_sio driver. New versions of Ubuntu/Debian/Fedora and most popular distributions include this by default.

If you're in Windows XP or above the USB FTDI driver will be autodetected if you allow it to search for drivers on Windows Update. If you go into "Device Manager" you will see the COM# device that was allocated.

In this example, my COM device is COM5.
