The primary difference between these two connection methods is the automatic IP address
assignment that DHCP provides in
(A)
.
(A)
DHCP Enabled Router, Server, or Router/Server/Switch Combo Connection
The Neutrino processor device boots up with DHCP enabled by default so with DHCP
enabled routers and servers Neutrino will automatically obtain an IP address upon power up
and connection. This may take a minute or two as the devices look for DHCP to obtain their
IP address.
Available DHCP is the recommended connection method.
Where our NeuPanel Series
wall controls will be used to control the processor we recommend the use of a low cost
router along with a POE switch. This combo will provide
DHCP
as well as power to the wall
controls over their Ethernet cable by way of the switches
POE
feature (Power Over Ethernet).
Note:
Linksys routers/NetGear switches have tested well (D-Link routers have not).
(B)
Non-DHCP Enabled Direct or Indirect Connection
When the processor is connected directly to a computer or indirectly via a switch or hub and
DHCP is not available to assign IP addresses - the connection process is not automatic.
(1)
A Single Processor or Device in the Network Only - No DHCP Available
Once no DHCP is detected - a single direct or indirectly connected processor device will
either try to connect using the IP address last assigned and stored in the device or
attempt to revert to is default IP address of 169.254.128.128. Under some conditions
the processor might refuse to relinquish its stored IP address or revert to its default IP
address and thus refuse to connect.
To simplify and speed this non-DHCP enabled
connection we recommend
- that before you power up your device you should
Reset
the processor to its
Default IP Address
using the
IP Reset Button
on the rear of the
processor. Resetting the processor to its default IP address of 169.254.128.128 will have
you connecting directly quickly and without problems when no DHCP is available.
