APPENDIX H — TOUCH PILOT
ETHERNET/IP CONNECTION PROBLEMS — If the unit
is point-to-point connected to a PC (the cable can be crossed or
uncrossed) and the unit is energized, it may be necessary to
check the Ethernet connection and/or configure the PC net-
work board. See also the section Unit Is Connected to the
Local Network below.
To verify the unit's IP address, perform the following steps:
1. From the computer connected to the Touch Pilot, go to
Local Area Connection Properties and select Internet Pro-
tocol (TCP/IP). See Fig. N.
Fig. N — Local Area Connection Properties
2. Click the Properties button. The Internet Protocol Proper-
ties window opens. See Fig. O.
3. Verify the IP address.
Fig. O — Internet Protocol Properties
If no IP address is configured in the General or Alternate
Configuration tabs, the unit IP address must be config-
ured to 169.254.xxx.xxx. Modify the unit IP address and
restart the system.
If the PC has a fixed IP address configured in the General
or Alternate Configuration tabs, the IP address of the PC
and the unit IP address must have the system and sub-sys-
tem fields in common. The last part of the IP address is
the host number and must be unique on the sub-system.
For example:
Unit address: 172.30.101.11
172.30.101.182. In this example 172.30 corresponds to
the network, and 101 corresponds to the sub-system.

4. Carry out all the necessary modifications, and click OK to
accept or Cancel to discard changes.
5. Try to access the unit again.
If it is still impossible to access the unit, ping the unit by fol-
lowing these steps:
1. Open a Windows command prompt using one of the fol-
lowing methods:
• Press the Windows logo key + R to access the Run
command. Then type the CMD command and press
Enter.
or
• Click the Start button and then click Run. Type the
CMD command and press Enter.
2. At the command prompt, type the ping command fol-
lowed by the unit IP address.
In the example shown in Fig. P, the PC receives four posi-
tive responses (replies).
Fig. P — Ping — Positive Replies
In the example shown in Fig. Q, the PC receives four nega-
tive responses (request timed out).
Fig. Q — Ping — Negative Responses
If the PC receives four negative responses, check the web
browser parameters to determine if a proxy server or an auto-
matic configuration script has been configured (see the section
Proxy Server and Automatic Configuration Script below). Ad-
ditionally, Java settings may require configuration (see the sec-
tion Javanet Connection below).
Try to access the unit again. If the PC still does not re-
ceive a response from the unit, restart the unit. Contact your
system administrator.
UNIT IS CONNECTED TO THE LOCAL NETWORK —
The unit is connected to the local network by an uncrossed
cable, and the unit is energized. From a computer connected to
the same network as the Touch Pilot, open a Windows com-
mand window (Start, Execute, type cmd and press Enter), then
type the command ping, followed by the unit IP address.
