Using Zero Configuration
30
Metreau Entry Communicators
Notice that the serial number is appended to the name of the device.
In this case the serial number is
218001WHP2980023
.
At this point, the device can be configured (changing IP settings, NetLinx settings, User settings, etc) via
the pages in the Configuration Manager (see the
Using the Configuration Manager
section on page 33).
Connecting In a Network Without a DHCP Server
By using the MET-ECOM zeroconf feature and the
Bonjour for Windows
plug-in utility, Dealers can
install and configure MET-ECOM/D devices one at a time in a network that does not have a DHCP
Server. In this case, the MET-ECOM/D devices revert to using a minimal implementation of 'link-local
addressing'.
To establish a network connection from a PC to the MET-ECOM device:
1.
Direct connect a PC and MET-ECOM device with the AMX PS-POE-AF single-port PoE Injector.
2.
Confirm PC assigned itself an IP address:
a.
If the PC's network interface is set to DHCP wait several minutes to ensure the PC reverts to
'link-local addressing'.
b.
You can confirm that the PC has assigned itself an IP by running
ipconfig
from a CMD shell.
The example in FIG. 26 shows the
Ethernet adapter Local Area Connection:
could not find a DHCP
server and assigned itself the IP address of 169.254.83.124 with Subnet Mask 255.255.0.0. This is a
valid link-local address.
If the PC did not assign itself a 169.254.x.x address, or if the PC assigned itself the address of
169.254.2.2
then proceed to Step 3. Otherwise skip to Step
4.
3.
Manually assign an IP address, via the
Internet Properties (TCP/IP) Properties dialog
(FIG. 27):
You may need to manually assign the IP on the PC if the PC does not support link-local addressing
or if the PC assigned itself the IP address of
169.254.2.2
.
This version of the MET-ECOM assigns itself
169.254.2.2
by default when it reverts to link-local
addressing. Therefore, in order to avoid conflict the PC
cannot
be assigned IP address
169.254.2.2
.
Alternatively, connect the PC and MET-ECOM to an Ethernet switch equipped with
PoE. Make sure only one MET-ECOM that is still at its factory default settings is
connected.
