CONTROLLING THE OT-1000-HH VIA NEC

The RS-485 interface is used to manage the OT-1000-HH, such as reading data and changing settings. It
is recommended to connect this interface to a network element controller like:

The Olson network element controller OT-NEC-A allows supervising and controlling the function of the
transmitter and other equipment connected to the RS485 master interface, using the integrated Ethernet
webserver (HTTP) interface.

In order to enable the communication with a NEC, the RS485 slave port of the OT-1000-HH has to be
connected with the RS485 master port of the OT-NEC-A as shown in the figure below. In general, this is
accomplished by the sub-rack bus wiring. 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 172.23.41.65.

Starting from OT-NEC-A application software release 1.12 or higher, a picture as shown below will ap­pear on the web screen when a web browser communicates with the NEC:

Figure 1 — Display of Web Browser (Microsoft Internet Explorer)

In “Devices” all devices are shown which are connected to and recognized by the NEC. In the de­vices-column user, defined aliasnames for the OT-1000-HH are shown. In the “Devices” overview win­dow the states, models, alias name, serial number, software and hardware releases are shown. By per­forming a mouse-click on one of the devices in the devices column, a device specific menu will open as
shown below.

For details on operating the OT-1000-HH via a NEC, please refer to the NEC operating manual.

STATUS MENU

The picture below shows the status menu of the OT-1000-HH.

Figure 2 — Status Menu

The actual status of the transmitter is shown using a mark and a description. There are several marks,
filled or unfilled, used to show all events.

 A green flag indicates that the transmitter is working properly.
 An orange (yellow) flag shows a warning. A certain parameter is out of the nominal range.

The unit should be checked and the problem resolved as soon as possible.

 Red flags indicate urgent alarms. An immediate action is required to fix the failure.
 An exclamation mark provides a message about a certain mode of operation or change

PARAMETER MENU

The parameters menu displays the most important operation values of the transmitter:

 RF input power (root-mean-square value)
 Optical modulation index (total root-mean-square value)
 RF Gain
 Optical output power
 Thermo electric cooler TEC current
 Laser bias current
 Laser temperature (offset to 25°C)
 Transmitter module temperature

Figure 3 — Parameter Menu

For a proper operation, the black vertical bars should meet the green fields.
Note: The scaling of the green and yellow fields might be different in order to obtain a good reading, es-

pecially of the green field.

VOLTAGES MENU

The voltages menu displays all internal supply voltages like shown below:

Figure 4 — Voltages Menu

For a proper operation, the black vertical bars should meet the green fields.

Note: The thresholds for alarms are not user adjustable but by factory setting only.
