Start troubleshooting from a known state. Power the unit OFF and ON to reboot. Is a proper IP address configured in the unit and PC? “Ping” it to see if it responds. From the Windows command prompt or “Run” dialog box, use thecommand:ping IP_AddressWhere IP_Address is the IP Address of the unit (e.g. ping 192.168.0.1 ). If it does notrespond, then check all LAN connections. If the LAN connection are OK, the problem is in theLAN addresses or routing The most common problem cause is incorrect IP addressconfigurations. Make sure the workstation and PR have compatible IP addresses. It may be that your "ARP table" contains invalid entries. You can clear the "ARP table" byrebooting, or, on Windows, by typing the following command at the command prompt or Rundialog box.: ARP * -d . This is a common problem with test-benchsetups. In some cases, “smart” hubs and switches must be power-cycled to clear their internal ARP cache.This is often a problem on test bench setups where IP addresses are moved between differentequipment or a unit is moved between Ethernet switch receptacles.45 |
