2. /dev/fd096ds15 (A:1.2M)
3. /dev/fd1135ds18 (B:1.44M)
4. /dev/fd196ds18 (B:1.2M)
5. Hard Disk /tmp/moxa
g.The shell script will install the driver files automatically.
The administration program 'npsadm' will then be activated.
3.3 Configuration
a.If the driver installation is successful, you can see the
main menu of administration utility.
- Add Server
- Delete Server
- Configure Server
- Ports Monitor
- Driver Removal
- Exit
b.Select 'Add Server' to add NPort Server, you can find two
options as follows to add NPort Server.
- Auto-Probe NPort Server
- Manual Add Nport Server
Select "Auto-Probe NPort Server", the npadm can search the
NPort Server on local LAN automatically. All of the NPort
Servers found are displayed in the list of 'Select NPort
Server to Add'. Select the NPort Server to be installed.
If you're not sure which NPort Server is the one for
installation, you may press Ctrl+B to locate the server
by observing the LED display.
If the NPort Server is not installed in the local LAN but
in different network, please select the 'Manual Add NPort
Server' to input the NPort Server's IP address manually.
c.Next, you can see a password dialog poped up. If the NPort
Server is password protected, please input the password and
select [ENTER] to continue.
Please note, if you input wrong password more than three
times, the administration program will go back to main menu.
d.Next, the 'Set Server Property' menu poped up for server
property configuration. You can modify the properties
i.e. server name, IP address, IP Netmask, Gateway, password
and DHCP setting. Select Ctrl+F to save the setting.
e.Next, the 'Set Port Property' menu poped up for serial
port property configuration. You can set the port status
i.e. mapping, device name, FIFO, interface.
The default device name of each port is '/dev/ttynxx'.
You can change the tty device name to you wanted.
Please note that each port must have a unique device name.
Select Ctrl+F to save the setting and exit.
f.After everything is set, the NPort Server will be restarted
and the driver will activate automatically.
g.The administration program stores all settinsg in '/usr/bin'.
You may run 'npsadm' to change the settings when necessary.
3.4 Check log file
You can check the driver log file 'npreald.log' in
'/usr/lib/npreal/bin'.
3.5 Add more server
Add Server allows you to add more NPort Server. You may refer
to 3.3.b for more detail.
3.6 Remove server
You may remove certain NPort Server from the list by entering
'Delete Server' function.
4. Maintenance
In addition to above functions, NPort Server administration program
also provides more utilities for better system maintenance.
4.1 Monitor
You can select the Ports Monitor of administration utility to
monitor each port's activity as well as to learn each port's
transmission status by running 'npadm' program. This utility
can report the data length and throughput of transmitting (Tx)
and receiving (Rx) when data transmission.
In this comparison table, you can see the 'Char Count', total
character counting, based on byte per second. In addition, per
Tx and Rx throughput reported in both of interval and average
based on byte per second.
The interval basis of throughput means the data transmission
rate is counted within interval setting i.e. based on 3 seconds.
And the average basis of throughput displays the average value
of entire data transmission rate.
We provide the function to change the interval number, 3 ~10
seconds, by pressing <+> and <-> key. Moreover, you can select
the port number then press <Enter> to view per port's status i.e
communication parameters, signals status, flow control status,
and idle time. If need, you can press the <Home> key to reset
the value to zero.
4.2 Serial port sharing and access right authorization
NPort Server allows multiple hosts access one serial port.
Therefore, proper access right authorization is necessary.
To configure the access right for each serial port on NPort
Server, you must enter the IP address of the host to be
authorized in this program.
Press "<Ctrl+G>: Set Grant IP" to configure port access
authorization.
4.3 Driver Removal
You can remove the Real TTY driver from your system by running
the Driver Removal function.
