35 TPC-650 User's Manual
Note: To verify that your TPC-650 has joined the network
and is properly connected with your host PC, just try
to access your host PC through the Windows CE
Explorer by typing //host_name_of_host_PC in the
address bar. Press Enter to search for the host PC.
If the connection is successful, you can see the
network shares that are available from the host PC.
Or you can simply "ping" your TPC-650 from your
host PC to make sure TCP/IP is working. (e.g.
c:\ping IP_address_of_your_TPC-650 or device_name_of
_your_TPC-650 )
4.3 Networking via RS-232
RS-232 is a time-honored standard interface for industrial automation.
It is very convenient to implement, albeit much more limited in its
communication distance. The TPC-650 is provided with a RS-232 port,
from which it can be connected to your host PC via a NULL modem
cable.
Please follow the procedures described below to set up network
connection between the TPC-650 and a host PC via an RS-232
interface:
1. Before connecting to RS-232, first make sure your COM port
service on the host PC has been enabled.
Note: If you are running Windows 95/98 on the host PC, the
COM port service should be enabled on default
without extra installation of other components. On the
other hand, if you are running Windows NT on the
host PC, make sure the RAS (i.e. Remote Access
Service) on your host PC system is running properly.
If you have not installed the RAS, you must install it
on your system.
2. Use the DB-9 NULL modem cable (that accompanies your TPC-650)
to connect the TPC-650 through its RS-232 port to the COM port of
your host PC.
