Sensoray 2411 User Manual

The v4l (Video4Linux) bttv is used for frame capturing driver in the 2411. All related modules are pre-
built and distributed with 2411 embedded Linux OS kernel. The version of the bttv used in the 2411 is
bttv-0.7.85.
The frame capturing can be initiated/controlled by software or triggered by a digital signal (for
example, from a push button) with hardware connection to GPIO port on 311 in the stack. A separate
device driver is used for GPIO operation (refer to Appendix-III for details).
After applying power, this system will automatically boot from the embedded Linux and be fully
functional after about 20 seconds.
The 2411 is set up to user’s desired mode of operation by modifying configuration files. Some
minimal knowledge of Linux would be helpful. There are two ways to accomplish this. The simplest is
to open a telnet session on a workstation connected to the network with the IP address (10.135.1.99,
default setting on factory 2411, which can be changed once you get accessed to the target 2411
unit). If this IP address conflicts with another node on your network, you will need to use an
alternative way connecting a dumb terminal (or terminal emulator (VT100) on a PC) to the serial port
(com1) on the 2411 (9600 baud, 8 bits, no parity). A step-by-step procedure will be given.
Procedures for setting up and getting started with 2411 are given below.
II. Setting up the 2411 via network connection (recommended):
1. Connect network cable to 2411. If the factory IP address (10.135.1.99) conflicts with your
network you need to follow the “Setting up the 2411 via serial terminal” procedure (in next
section).
2. Connect +12V to +24V DC to the Power Supply board, Model 207 in the stack. Turn on the
power.
3. Wait 20 seconds, or till system boot up.
4. Open a telnet session on a workstation connected to the network and telnet to 10.135.1.99.
HINT: From a Windows based workstation a telnet session can be opened from a DOS
window (Command prompt window), typing 'telnet 10.135.1.99' and then pressing
5. At ‘2411 login’ prompt, type ‘root’ and then press
6. At ‘Password’ prompt, type factory password and press
7. You should now see “2411SYS:~ #”. If you mistyped something and the login failed, just press
8. Type ‘cd /usr/etc’ to take you to the directory containing the user modifiable configuration files.
9. Type ‘ls’ and a listing of the files will be shown.
10. Now the IP address can be changed. At the shell prompt, type
‘netconfig eth0 -i your_ip -m your_netmask’ and then press
for example, ‘netconfig eth0 -i 192.168.1.23 -m 255.255.255.0’
Once done, reboot the 2411 (at the shell prompt type 'reboot' and then press
11. Another way to modify the IP address, is to edit the ‘system.config’ file by typing “vi
/usr/etc/system.config”.
