AWK-1121/1127 Software Installation and Configuration
4-15
Hardware Setup
Before proceeding with the software installation, make sure you have completed the hardware installation.
Note that the default IP address for the LAN interface of AWK-1127 is 192.168.127.253.
NOTE
After install
ing the hardware, you must configure the operation mode of the serial port on your AWK-1127
to
RealCOM
mode.
Installing Linux Real TTY Driver Files
1. Obtain the driver file from the included CD-ROM or the Moxa website, at http://www.moxa.com.
2. Log in to the console as a super user (root).
3. Execute cd / to go to the root directory.
4. Copy the driver file moxa_oncell_realtty.tgz to the / directory.
5. Execute tar xvfz moxa_oncell_realtty.tgz to extract all files into the system.
6. Execute /tmp/oncell_realtty/mxinst.
For RedHat AS/ES/WS and Fedora Core1, append an extra argument as follows:
# /tmp/oncell_realtty/mxinst SP1
The shell script will install the driver files automatically.
7. After installing the driver, you will be able to see several files in the /usr/lib/oncell_realtty/driver
folder:
> mxaddsvr (Add Server, mapping tty port)
> mxdelsvr (Delete Server, un-mapping tty port)
> mxloadsvr (Reload Server)
> mxmknod (Create device node/tty port)
> mxrmnod (Remove device node/tty port)
> mxuninst (Remove tty port and driver files)
At this point, you will be ready to map the AWK-1127 serial port to the system tty port.
Mapping TTY Ports
Make sure that you set the operation mode of the desired AWK-1127 serial port to RealCOM mode. After
logging in as a super user, enter the directory /usr/lib/oncell_realtty/driver and then execute mxaddsvr
to map the target OnCell serial port to the host tty ports. The syntax of mxaddsvr is as follows:
mxaddsvr [OnCell IP Address] [Total Ports] ([Data port] [Cmd port])
The mxaddsvr command performs the following actions:
1. Modifies oncellreald.cf.
2. Creates tty ports in directory /dev with major & minor number configured in oncellreald.cf.
3. Restarts the driver.
Mapping tty ports automatically
To map tty ports automatically, you may execute mxaddsvr with just the IP address and number of ports, as
in the following example:
# cd /usr/lib/oncell_realtty/driver
# ./mxaddsvr 192.168.3.4 1
In this example, one tty port will be added, with IP 192.168.3.4, with data port 950 and command port 966.
