5.1.3 Network Tab
This screen has information about the Ethernet interface. Most importantly, this is where you may assign a
known IP address to the EM1500. If you are using DHCP, an IP address entered here will be used as a
backup if the DHCP attempt fails.
Figure 5.4 Network Tab
IP address
To assign a static IP address to the EM1500 enter it in this text box. Make sure “Use
DHCP” is unchecked.
If “Use DHCP” is checked, any IP address entered here will be used as a fallback if
DHCP is not available.
IMPORTANT: If the EM1500 is no longer readily accessible (i.e., it’s no longer on
your desktop or maybe it’s not even in the same building) changing its IP address or
netmask should be done with great caution. It is possible to assign an IP address or
netmask to the unit that causes it to no longer be able to communicate across the
Internet. The only way to recover from this requires physically touching the unit to
reset it.
Netmask
Like an IP address, the netmask may be obtained from your network administrator. It
specifies subnetting of the IP address.
