0 – NTP Servers
The device can be configured to synchronize its clock with NTP time. Enter the IP address
or DNS name of a primary and, optionally, a secondary NTP server. The device will use
NTP as a time source if the time sync source in the system configuration is set to
NTP
.
a - Connection Keep Alive
The L-IP allows to automatically ping other devices on the IP channel in order to maintain
an IP connection that might be automatically disconnected after a specific period of time
(e.g. DSL routers automatically disconnect if no activity is detected). The options to choose
are:
Select connection keep alive mode
(0 - disabled, 1 - auto IP, 2 - custom IP):
Enter 0 to disable this feature, enter 1 for auto IP mode and 2 to specify one IP address that
should receive the pings. If auto IP mode is selected and the L-IP works as a configuration
server, a ping message is sent to all devices in the device list of the configuration server. If
the configuration server is disabled on this L-IP a ping message is sent to the configuration
server for the IP-852 channel.
Please refer to Section 5.10 on how to monitor the automatic keep-alive feature and to
display the ping response times for the different devices on the IP-852 channel.
b - Link Speed & Duplex
If the L-IP is operated with an old 10Mbit/s-only hub the link speed should be switched
from “Auto Detect” to “10Mbps/Half-Duplex”. With modern 100/10Mbit/s switches this
setting can be left at its default.
5.7 CEA-852 Device Configuration Menu
This menu holds relevant information regarding the configuration of the CEA-852 device.
Depending on the configuration method of the L-IP one can either input the configuration
data in this menu and the L-IP then contacts the configuration server or the preferred
method is to enter the information at the configuration server and the configuration server
then contacts the device (L-IP) and fills in the relevant information in this menu. The device
configuration menu is shown in Figure 35.
