CONTROLLING A NEC
In general the ES10/ES26 is connected to a network element controller NEC which can be
•
a NEC which is directly embedded in the 19’’ housing.
This is the case of an ES10XLa or ES26XLa.
•
a NEC-E, a network element controller in BK-housing
(with LCD, push buttons and 12 general purpose I/O ports)
•
a NEC-E-19’’, a network element controller in 19”-1RU housing
providing 12 general purpose I/O ports or
•
an embedded NEC in other BKtel products
such as an optical amplifier OVxxxxa or a direct modulated transmitter DS26
The NEC allows supervising and controlling the function of the transmitter and other equipment
which is connected to the RS485 master interface, using the integrated Ethernet webserver
(HTTP) interface.
In case of the ES10XLa/ES26XLa the NEC-E is embedded and a connection between NEC-E
and ES10/ES26 has been established internally. In order to enable the communication of an
ESxb with a NEC, the RS485 slave port of the ESxb has to be connected with the RS485 master
port of the NEC. The NEC Ethernet interface has to be connected to a PC either directly via a
crossed Ethernet cable or via a LAN. It is important to set the IP address of the NEC in order to
be compatible with the available LAN IP addresses. The IP address can be changed using the
push-buttons and the LCD (please refer to NEC operating manual). In the example below the IP
address has been set to be 172.23.41.113.
6.1 Communicating with the NEC
If a Webbrowser gets in touch with the NEC of the transmitter a display as shown below will
appear within the Webbrowser (e.g. MS Internet Explorer):
