Comtrol RocketPort Serial Hub Si 8-Port - Manual (Page 5)

Using the IP Configurator Utility 5 of 9
Note: The diagnostic is available in several places,
including Comtrol media (diskette or CD) and
the ftp/web sites.
1. Turn the Power switch to the OFF position.
2. Disconnect the Ethernet cable from the RocketPort
Serial Hub Si.
3. If necessary, extract the diagnostic if you
downloaded it from the ftp/web or if you are using
the Comtrol CD.
Note: If the RocketPort Serial Hub Si is not
located near your server, you can use
another computer or laptop to run the
Diagnostics and IP Configurator utility.
4. Execute the sidiag.exe program in a native MS-
DOS
®
environment.
Note: The Diagnostic and IP Configurator Utility
takes a few moments to load.
5. At the first screen, press the B key to start the
diagnostic.
6. Connect a null-modem cable from a COM port on a
PC (COM1 or COM2) to Port 1 on the RocketPort
Serial Hub Si.
7. Press the 1 or 2 and Enter keys to represent which
COM port on the PC to which you are connected.
8. Press the 4 or 8 and Enter keys to represent the
number of ports that the RocketPort Serial Hub Si
contains.
9. Optionally, test the ports that use RS-422 or RS-
485 mode.
a. Select a port number (2 through 4 or 8) that you
want to test for RS-422 or RS-485 and press
the Enter key.
b. Select the appropriate mode (it is not necessary
to press the Enter key).
Note: You must test RS-485 in pairs because it
requires a loopback cable.
10. Press the A and Enter keys after selecting the
appropriate mode for each port or to test all of the
ports in RS-232.
Note: You can not test Port 1 in the same way that
you can test the other ports, but if the
diagnostic is running, then RS-232 mode is
functioning properly on Port 1.
11. Plug the loopback plug (RS-232 or RS-422) or the
loopback cable (RS-485) into Port 2.
Note: If you are testing RS-485, plug the other end
of the loopback cable into the port that you
selected in Step 9
12. Turn the RocketPort Serial Hub Si Power switch to
the ON position and wait for the Port 1 LED to
start blinking.
13. Press any key after the Port 1 LED starts to blink.
14. Follow the directions on the screen when the
diagnostic directs you to move the loopback plug or
cable to a particular port.
Note: If you want to turn off the AIOPIC Memory test,
you can run the diagnostic from a DOS window
with a -s option.
If the Diagnostic reports errors, see the table in
Diagnostic and IP Configurator Error Messages .
Using the IP Configurator Utility
The IP addressing scheme has the following
advantages:
• Uses an industry standard protocol.
• Allows you to configure servers to use ports on the
RocketPort Serial Hub Si that are outside of the
server’s Ethernet segment.
The MAC addressing method has the following
advantages:
• Simplifies implementation and ongoing support by
eliminating the address administration issues
inherent in network protocols. MAC addresses are
predefined by Comtrol and there is no potential for
an “address conflict” at setup.
• It is isolated from foreign LAN segments, which
minimizes potential security issues.
There are two ways to configure IP addresses for the
RocketPort Serial Hub Si:
• If running an ARP or DHCP environment, you must
reserve an IP address for the MAC address of the
RocketPort Serial Hub Si. If you are using this
method, it is not necessary to configure an IP
address using the RocketPort Serial Hub Si IP
Configurator utility.
• If not running an ARP or DHCP environment, you
can use the IP Configurator utility mentioned in the
following discussion to set an IP address in the
RocketPort Serial Hub Si BIOS.
The IP Configurator utility uses Port 1 on the
RocketPort Serial Hub Si to communicate to a COM
port on a PC (COM 1 or 2).
