If your E-PDISO16 is connected directly to a computer via a cross-over cable or a single hub/switch, check
to see if the
ACTIVITY
LED flashes when you try to communicate with the module. The ACTIVITY LED
flashes if there is any traffic coming from the computer. If it is not flashing at all, there are two
possibilities:
There is an issue with the TCP/IP settings that is keeping your computer from transmitting. Verify that
your TCP/IP settings are correct, and that you are using a valid IP address for both your computer and
E-PDISO16. A simple way to do this is to open a DOS Command Prompt window from your
computer. Run the DOS prompt from Start►Programs►Accessories►Command Prompt. When the
DOS window opens, type in "IPCONFIG" and press the
Return
key.
Your computer should return a message similar to the message shown here.
If the IP Address or Subnet Mask information are all 0’s, or if the first three numbers in either the IP
address or IP Mask do not match the settings set in the E-PDISO16, then the computer will not be able
to communicate with the E-PDISO16. If you are unfamiliar with how to set these parameters on your
computer, check with your network administrator.
