 Since the static IP address of the M2TE also has a network ID of 192.168.1.0 (its IP address is
192.168.1.36) the PC is able to communicate with it.
 Remember IP addressing can be much more involved and complicated but the above example
should be enough to get things working.
A.2. DHCP (Dynamic Host Configuration Protocol)
 DHCP is an automated means of assigning a unique IP address to a device on a network. The
M2TE can be set up for DHCP, see section 7.7.4. If the server network to which the M2TE is
connected provides DHCP services then it may be more practical to switch to DHCP addressing.
 Keep in mind if the M2TE is set up for DHCP addressing then each time the it gets attached to
the computer network the IP address may change (depending on the configuration of the DHCP
server; the IP addresses that it issues are leased for an limited amount of time, once the leased
has expired a new IP address may be issued). Hence when the M2TE IP (Ethernet) cable is
attached to the computer network it may be necessary to find the current IP address. See
section 6.6.5.1 “Report IP Address”.
 Also be aware if the M2TE is set for DHCP addressing and the IP (Ethernet) cable of the unit has
not been attached to a computer network then the reported IP address will show all 0’s, for
example 0.0.0.0. If this is the case make sure to attach the M2TE IP cable into the network
which has a DHCP server and that the M2TE has been set for DHCP addressing.
Finally remember that through the serial port, see section 7.4 you can view the current IP settings, the
current addressing mode and the current IP. In addition you can change the mode and set a static IP
address using the serial port.
