It is useful to specify the MorphoAccess® SIGMA Family terminal by its host name, when the
DHCP mode is enabled, as the IP address of the terminal can change after a power up.
LAN without DNS Server
This section helps the administrator in connecting the MorphoAccess® SIGMA Family terminal
to a LAN that does not have a DNS server or when host name cannot be added to the DNS Server
database.
The PC is not able to establish a connection with a terminal using its host name. An IP address
of the MorphoAccess® SIGMA Family. terminal is the only way to specify the terminal.
For standard use (excluding unscheduled maintenance operations), it is recommended that the
administrator should not enable DHCP mode in this case. This is because in the DHCP mode the
IP address for the terminal can change each time it is restarted.
Static IP address (DHCP disabled)
This is the easiest way for an administrator to connect a MorphoAccess® SIGMA Family terminal
to a LAN. In this case, the IP address of the terminal remains the same after each reboot and
the Host System needs to know only this IP address in order to establish a connection with the
terminal.
The IP address of the MorphoAccess® SIGMA Family terminal must be reserved in the router by
the network administrator. The network administrator must also provide and/or approve the
network parameter values for the terminal, i.e.:
The MorphoAccess® SIGMA Family terminal IP address,
Gateway IP address,
Local subnet masks value.
WARNING: If the MorphoAccess® SIGMA Family terminal uses an IP address already
assigned in the network, the connection to the terminal will be unstable.
Dynamic IP address (DHCP enabled)
When the administrator enables the DHCP mode in the terminal, the terminal IP address and
other
networking parameters
are assigned automatically from the DHCP Server (network
routers). This address could be different after each start-up as it depends on the DHCP strategy
defined for the LAN.
