the connection can be given a name and saved just like the TCP/IP connections, so that the
procedure is only necessary when the address of the device changes.
Connecting via CEA-709 is most suitable when the device is not connected to the IP
network and a non-LNS network management tool is used for integration.
ADVANTAGES:
Works even when the device is not connected to an IP network, thus no need to
set up TCP/IP settings for the device.
Download is faster compared to LNS
®
connections, due to an optimized file
transfer protocol.
Works independent of the used network management tool.
LIMITS:
Only works when the device is commissioned. A download of a new project
which changes the static interface of the device will therefore break the
connection, since the device will have to reset its CEA-709 network
configuration in that case. The device must then be re-commissioned in the
network management tool and the connection must be re-established.
Especially in FT-10 mode, project downloads can still be slow. The same is true
for firmware downloads. If possible, the TCP/IP connection method should be
used for such tasks. Transfer speed is considerably improved when there are no
routers with limited buffer size between the PC and the device. Routers which are
able to handle large packets (254 byte) will have no real impact on the transfer
speed. Routers which allow a maximum packet size of 64 bytes only will degrade
the transfer speed.
Only network interface hardware from LOYTEC can be used for this type of
connection. Any LOYTEC NIC may be used to run the configuration software,
that is, the software is not registered to specific network interface hardware.
There is currently no way to conduct a network scan using this connection
method, since the built-in scanner engine on the device can only be controlled
using a TCP/IP connection.
3.2.2.3 TCP / IP Connections
As discussed earlier, this method connects to the device through a standard TCP/IP channel.
Regarding integration of CEA-709 capable devices, the following advantages and
disadvantages should be considered.
ADVANTAGES:
Very fast data transfer, suitable for large projects.
Best way to update the firmware of a device fast and secure.
Communication is possible even when the device is not commissioned or
otherwise not reachable on the CEA-709 port.
No LNS
®
or special network interface hardware is required. The standard
Ethernet port which is available on every PC is enough.
