CHAPTER 3
Start-up and Testing

If there is a problem, it may look like:
C:\> ping 152.115.61.100
Pinging 152.115.61.100 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
This means that the PC did not receive any response from this IP address. It could be due to
the following reasons:
• The front-end has another IP address than you expect (in this case different from
152.115.61.100). See section 2.7.2 for information on how to change the address
• The network interface on the front-end is not working correctly
• You are using very long network cables (not very likely)
Another problem looks like this:
C:\> ping 152.115.61.100
Pinging 152.115.61.100: 32 bytes of data:
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
This means that the IP address of the front-end is of a different address class than the PC.
This is a very typical case because the system is shipped from Brüel & Kjær with the default
IP address 10.10.10.11 and this needs to be adapted to your specific LAN/in-house network.
Normally only the last number in the IP address will differ between the workstation and the
front-end, e.g., 152.115.61.99 and 152.115.61.100.
Possible solutions:
• The simplest solution is to change the IP address of the front-end using the RS–232 inter-
face, as described in section 2.7.2
3.4 User Test Program – Verifying System Operation
The user test program can be used to verify the operation of the system or to locate a faulty
module. The program is intended to be self-explanatory.
The program is pre-installed in the PROM of all controller modules.
Basic Requirements – Hardware
The test can be performed via a VT100 terminal with a baud rate of 9600 or from a PC with
a terminal emulation program running under Windows
