Integrator Series Room Combine 788
Network Configuration
TThe 788 is setup and controlled by a host computer via
Ethernet. This requires the host computer to be connected
to the 788 directly via a standard CAT5 Ethernet cable,
indirectly via an Ethernet switch, or via an existing Ethernet
network.
The primary difference between the three methods of
connection is that in the first two, the 788 software
application assumes there is no DHCP server or other
network infrastructure in place. It assumes the 788 is using
a self-generated IP address and adjusts its connection steps
appropriately. In the third method, it is assumed that a DHCP
server and/or router with DHCP server are already present
on the existing network so the 788 may already have
obtained an IP address. Consult your network administrator
if in doubt.
General Notes
1. The 788 boots up with DHCP enabled by default. This
means that as soon as you connect it to a network, it will
look for a DHCP server in order to obtain an IP address. If
a DHCP server is present, the 788 will get its IP address
from it. This process may take several minutes. With your
PC attached to the same network and thus getting its IP
address from the same DHCP server, all will be ready to
go.
2. If your network does not have a DHCP server, the 788
will not be able to obtain an IP address. While waiting,
the 788 will default to a private IP address in the range
of 169.254.x.x where x.x is the last four alphanumeric
characters of the 788’s MAC address. The 788’s MAC
address can be found on a sticker on the bottom of the
788 or within the front panel System menu. When there is
no DHCP server present to assign IP addresses to either
the 788 or your PC, you may need to configure your PC
with a static IP in the range of 169.254.x.x with a Subnet
Mask of 255.255.0.0 in order to communicate with the
788 in a direct connect mode. However, if your PC is
using the default network settings, it should also have
automatically self-assigned a similar private IP address
in the range of 169.254.x.x, and if this is the case, you
should be able to connect to the 788 directly. Even if the
PC’s default settings have been changed, the 788 will try
to establish communications by setting up appropriate
routing table entries to reach devices with 169.254.x.x
addresses.
3. In the case of the first two methods (direct connection
and indirect connection), the 788 software will attempt
to set-up appropriate routing table entries for a seamless
connection regardless of the IP addresses of your PC
and 788. However, under Windows® Vista, administrative
privileges are required to allow the 788 software to
modify the routing table. For best results, launch the 788
software while logged in as an administrator, or choose
to run the software as an administrator.
Note:
To run
a program as the Administrator under Vista, right click
on the program’s icon or shortcut and choose “Run as
administrator”.
4. The 788 will display its current IP address, subnet
mask, and gateway as well as other useful information
on the front panel display when in System Mode. To
enter System Mode, hold down the Menu button for 5
seconds. Then the up and down arrow keys can be used
to move between various displays. This information may
be useful for troubleshooting.
Network configuration of the 788:
Connecting to the 788 from a host computer on the
same LAN
Both the 788 and the host computer require the following
3 items:
1. IP Address - The unique address of a node on a network.
2. Subnet Mask - Configuration that defines which IP
Addresses are included in a particular subnet.
3. Default Gateway (optional) - The IP address of a device
that routes traffic from one subnet to another. (This is only
needed when the PC and 788 are on different subnets).
If you are putting the 788 on an existing network, a network
administrator will be able to provide the above information or
it may have been provided automatically by a DHCP server.
For security reasons, it is not recommended to put the 788
directly on the Internet. If you do, a network administrator
or your Internet Service Provider can provide the above
information.
