Advanced troubleshooting
In order to determine if the problem comes from communication between computer and
device, or from the software, it can be useful to "ping" the T-44/48, that is to say to carry a little
test in order to see if the T-44/48 answers to a request via the network, without using System
Engineer (a very well-known test for networking amateurs)
•
Find the T-44/48 current IP in
UTILITY
→ “Current IP”
•
Open Windows command pront: Start Menu → type “cmd” in Start Menu search bar
→ click on the “cmd” icon.
•
In the command prompt, after “>”, type “ping”, followed by a blank space, and by
the T-44/48 IP address (4 integers separated by dots). For instance, for a T-44/48
with IP address 192.168.1.100:
Ping 192.168.1.100
•
A messenger “Pinging 192.168.1.100 with 32 bytes of data” appears, followed by
several line.
1. If all lines consist in the following message: "Request timed out", the connection does
not work. In this case, verify the connection between the computer and the T-44/48:
cables, plugs, RJ45 ports LEDs blinking, as well as IP settings. Verify that your network
card works, with a working and up-to-date pilot. Try automatic and manual mode, with
or without DHCP server, with our without router if you have one.
2. If messages such as "Reply from (T-44/48 IP address)", followed by pieces of
information (time, statistics, etc.), then the computer and the T-44/48 are correctly
configured and able to see each other.
In this case, verify System Engineer settings: does Ethernet network appears in the left
panel, is " System Engineer.exe" authorized in all firewalls, is .Net Framework 3.5 or 4
installed and up-to-date?
