NPort W2150/2250 Plus Series User’s Manual Installing and Configuring the Software
11-18
1. Obtain the driver file from the Document and Software CD, or from 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 npreal2xx.tgz to the / directory.
5. Execute tar xvfz npreal2xx.tgz to extract all files into the system.
6. Execute /tmp/moxa/mxinst. (For RedHat AS/ES/WS and Fedora Core1, execute
“# /tmp/moxa/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/npreal2/driver
folder:
mxaddsvr (add server, map TTY port)
mxdelsvr (delete server, undo TTY port mapping)
mxloadsvr (reload server)
mxmknod (create device node/TTY port)
mxrmnod (remove device node/TTY port)
mxuninst (remove TTYport and driver files)
At this point, you may map the TTY port to the NPort serial port.
Mapping TTY Ports
Make sure that you set the operation mode of the desired NPort serial port to Real COM mode.
After logging in as a super user, enter the directory /usr/lib/npreal2/driver and then execute
mxaddsvr to map the target NPort serial port to the host TTY ports. The syntax of mxaddsvr is as
follows:
mxaddsvr [NPort IP Address] [Total Ports] ([Data port] [Cmd port])
The mxaddsvr command performs the following actions:
1. Modify npreal2d.cf.
2. Create TTY ports in directory /dev with major and minor number configured in npreal2d.cf.
3. Restart 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/npreal2/driver
# ./mxaddsvr 192.168.3.4 16
In this example, 16 TTY ports will be added, all with IP 192.168.3.4, with data ports from 950 to
965 and command ports from 966 to 981.
Mapping TTY ports manually
To map TTY ports manually, you may execute mxaddsvr and manually specify the data and
command ports, as in the following example:
# cd /usr/lib/npreal2/driver
# ./mxaddsvr 192.168.3.4 16 4001 966
