6. Troubleshooting
6.1 The em.exe cannot find the unit
The em.exe will not find the device if it is not in the same sub-net
as the client PC. If you connect the PC to unit directly instead of
via a Ethernet Hub, you have to use a cross-over LAN cable if
your host Ethernet port does NOT support auto cross-over feature
(the Gigabit Ethernet supports auto-cross over feature, in this
case either straight or cross-over LAN cable will work). Then you
have to change your Ethernet Port’s Internet Protocol (TCP/IP) to
Static IP instead of Dynamic IP. Set the Its IP address to the same
sub-net as the Gateway unit (the Gateway’s default IP address is
192.168.1.254, DHCP is disabled), for example 192.168.1.1 as the
following screen shot.
