Configure Linux for serial communication

If you do not have a terminal emulator, such as Minicom, you must obtain one prior to completion of this task.

To configure Linux for serial communication:

IMPORTANT While Linux systems do not require installation of a device driver, it might require USB parameters as you

load the device driver to enable controller recognition.

modprobe usbserial vendor=0x210c product=0xa4a7 use_acm=1

You may also choose to incorporate the same information into the /etc/modules.conf file.

1. Determine if the operating system recognizes the USB (ACM) device by entering a command:

cat /proc/devices |grep -i "ttyACM"

If the OS discovers a device driver, it responds with the device number followed by ttyACM, for example:

116 ttyACM

2. To query the system about USB buses and the devices connected to them, use the list USB command:

lsusb

If the OSdiscovers a USB device driver, it responds with the single serial port, using the USB parameter hex codes:

ID 210c:a4a7

This confirms that the appropriate USB (ACM)device is visible to the management computer.

3. Invoke Minicom to configure it.

minicom -s

Select Serial Port Setup from the menu.

5. Select the parameter setting you want to change at the prompt by typing the related setting letter (A-G).

Setting Description Parameter settings

A Serial device /dev/ttyACM0

B Lockfile location /var/lock

C Callin program

D Callout program

E Bps/Par/Bits 11520 8N1

F Hardware flow control No

G Software flow control No

6. Press the ESC key to shift from the parameters to the configuration menu.

Select Save setup as dfl to save the parameter settings to default.

Select Exit from Minicom.

Configure Windows for serial communication

Use the terminal emulator to launch the device driver window and directly communicate with each controller module, after

meeting the following prerequisites:
