General Description

• The TELINK-SNMP1, manufactured by R.V.R. Elettronica SpA, is an SNMP telemetry interface via LAN that can be connected to all standard equipment manufactured by RVR.
• The TELINK-SNMP1 have been designed for installation in a 1HE box for 19” rack.
• Two major features of TELINK-SNMP1 are compact design and user-friendliness.
• Design is based on a modular concept: the different functions are performed by modules that, for the most part, are connected through male and female connectors or through fl at cables terminated by connectors. This design facilitates maintenance and module replacement.
• The TELINK-SNMP1 is an interface endowed with a microcomputer and a resident RTOS operating system specialized in the simultaneous management of data passing between 4 serial ports.
• The TELINK-SNMP1 opens the standard telemetry channel of RVR, available on connector DB9 and normally connected to high-level telemetry systems of stationlike ANTLAN, SNMP.
• It also include a Web Server that allows to be connected in ethernet network and to be explored by MIB browser. Supports E-mail messages to report possibly system errors.
• The SNMP protocol is managed by a DSP at 120 MHz inside the TELINKSNMP1.
• The Web server port can be connected to internet network and through a DNS link, the TELINK-SNMP1 can be interrogated by an IP address (i.e. 192.168.0.167).
• All signals and the power supply are provided with connectors for a quick replacement.
• The power supply is galvanically isolated and the signals are fi ltered to have an high immunity to RF disturbances.
• In rear panel there are ten led to a complete synoptic on the serial line traffi c and diagnosis on error type.
• TELINK-SNMP1 is equipped with watchdog hardware to reset the equipment automatically in case of abnormal stop of processor or in case of lowering below the threshold about power supply voltage.
• TELINK-SNMP1 has a “simulation” modality that allows to connect an ANTLAN system regularly to TELINK-SNMP1 and reading the virtual value (test of the protocol and network).
• The rear panel features the mains input connector, as well as the telemetry input connector, the dip-switch for the confi guration of the Main card and the programming connector both for the Main card and for the SNMP ANTLAN card.

Installation and configuration procedure

• This section provides a step-by-step description of equipment installation and configuration procedure. Follow these procedures closely upon fi rst power-on and each time any change is made to general confi guration, such as when a new transmission station is added or the equipment is replaced.
• Once the desired confi guration has been set up, no more settings are required for normal operation; at each power-up (even after an accidental shutdown), the equipment defaults to the parameters set during the initial confi guration procedure.
• The topics covered in this section are discussed at greater length in the next sections, with detailed descriptions of all hardware and fi rmware features and capabilities. Please see the relevant sections for additional details.

IMPORTANT: when configuring and testing the transmitter in which this telemetry unit is integrated, be sure to have the Final Test Table supplied with the equipment ready at hand throughout the whole procedure; the Final Test Table lists all operating parameters as set and tested at the factory.

Preparation

Preliminary checks

Unpack the exciter and immediately inspect it for transport damage. Ensure that all connectors are in perfect condition. Provide for the following (applicable to operating tests and putting into service):

• Mains power supply, 230 VAC (-15% / +10%), with adequate earth connection.
• Connection cable kit including:
  • Mains power cable;
  • Telemetry signal cable (cable with DB9 connector, not included);
  • Crossover RS232 cable (cable with DB9 connector, not included) for direct connection to PC;
  • Ethernet cable (cable with RJ45 connector, not included) for connection to ADSL router or LAN network;
  • Crossover Ethernet cable (cable with RJ45 connector, not included) for direct connection to PC.

Connections

1. Connect the RS232 output of transmitter to the RS232 input of the TELINKSNMP1 interface, through the RS232 cable.
   • Note: If you intend to connect it directly to a PC, it is necessary to use a crossover RS232 cable (i.e. when you need to program the Main card). This is a basic prerequisite to ensure equipment correct operation.
2. Connect the ETHERNET output of TELINK-SNMP1 interface to the appropriate input of your ADSL router or LAN network. If the connecting device is different, identify an equivalent.
   • Note: If you intend to connect it directly to a PC, it is necessary to use a crossover ethernet cable (i.e. when you need to program the SNMP ANTLAN card). This is a basic prerequisite to ensure equipment correct operation.
3. Connect the network cable to the relevant MAINS VOLTAGE connector on TELINK-SNMP1 interface.

First Power-On and Set-Up

Perform this procedure upon fi rst power-up and each time you make changes to the configuration this component is integrated into.

Web User Interface (WUI)

Once all connections previously described are performed, the equipment is ready for commissioning. The WUI (Web User Interface) allows you to adjust, modify or display the configuration variables such as IP, netmask and gateway address. Follow the procedure below to open the WUI:

1. Open your web browser on your PC, and connect to http://192.168.0.167 address to connect to the WUI (if LAN IP address was previously modified, it is necessary to use the new one). At this point the following page opens.
   • By factory the RVR uses the following adjustments:
   • IP address: 192.168.0.167
   • Netmask address: 255.255.255.0
   • Gateway address: 192.168.0.1
   • Note: If address http://192.168.0.167 does not work, check and set IP address as 192.168.0.XXX (where XXX is a figure between 0 and 255, excluding 167 thatis TELINK-SNMP1 interface default address). To change the IP address, follow the instructions in the manual or in the online guide and technical help, specifi c for the Operating System you use.
2. Modify the parameters in accordance with the own needs.
3. Now interface is ready to remotely read data and modify the various settings of the equipment.

SNMP telemetry

SNMP (Simple Network Management Protocol) is a worlwide protocol that allows the management and supervision of the equipment connected to the network. Measurements and commands are described by a MIB (Management Information Base), which is a list of OID (Object Identifi er). Each OID is a variable that can be written (SET) or read (GET) through a NMS (Network Management System) compatible with SNMP. The MIB is a text fi le written in ASN.1 and it is imported from the NMS in order to know what OID can be expected by the AGENT (proxy card, alias SNMP ANTLAN in this case) and how to interpret the information received. On request, the MIB may be associated with the transmission of e-mail.

Note: The user can not freely distribute the MIB, unless written authorization issued by the manufacturer. The MIB is property of the manufacturer. The SNMP version used in this application is the v2, and is compatible with all NMS systems.

Here is the list of MIB necessary for equipments of RVR equipments:

Note: Use a MIB BROWSER (not included) to use the MIB of RVR equipments. These are usually provided in an accompanying CD with the system in which the TELINK-SNMP1 is installed.

Management Firmware

Reading and Settings of Measurement

Each transmitter has a range of measures that can be read. Please refer to MIB for a detailed description of each measurement. The transmitter has an SCI (Serial Communication Interface) owner, that reads and stores the telemetry data in the Main card. The Main card then sends the data to the ANTLAN SNMP card for formatting/analysis which fi nally export the data obtained as SNMP. In the following you can fi nd the list of typical measures of transmitter. For simplicity are shown only those related to 10kW transmitter, but the same tree is also used to power different transmitters.

Note: In the following examples is used a MIB browser of ANTGroup, but any MIB Browser can be used.

The MIB are specified the range and description of each variable, in this case the forward power and possible alarms, which are reported into the description box at the end. If the READ ONLY and MANDATORY conditions are present, they mean that the value is been obtained.

Each input is associated to a tree for alarms settings. The tree for alarms settings (or trap settings) can be found in section 110 of each subtree. The adjustment of the class is not used in this release. For each analog measurement can be set:

• The maximum value (MAX) is the fixed point beyond which is sent a TRAP.
• The minimum value (MIN) is the fixed point below which is sent a TRAP.
• The hysteresis value is a nominal value that the system adds (or subtracts) to real value in order to exit from alarm condition. In other words, it is helpful to avoid situations of continuous alarm, if readout is very close to the set point alarm.

As you can see the hysteresis is a protected area in which the alarm is not sent, when the value exceeds the minimum value (MIN) when there is no alarm or the maximum value (MAX) alarm is active, the minimum value (MIN) alarm is set. To exit the MIN alarm condition, the value should be equal to the MIN value plus the value of hysteresis.

Note: the hysteresis value must be less than ½ referred to distance between the minimum value (MIN) and maximum value (MAX).

An example of an analog alarm setting, are included in the following section in the SNMP tree:

Reading and Settings of Status

Similarly to measurements described in the previous chapter, each transmitter has a range of states that can be read. Please refer to MIB for a detailed description of each measurement. The transmitter has an SCI (Serial Communication Interface) owner, that reads and stores the telemetry data in the Main card. The Main card then sends the data to the ANTLAN SNMP card for formatting/analysis which fi nally export the data obtained as SNMP.

Each input is associated to the tree of alarms settings. Similarly to measurements described in the previous chapter, the structure for alarms settings (or trap settings) can be found in section 110 of each subtree. For each analog measurement can be set a maximum (MAX) and minimum value (MIN). The adjustment of the class is not used in this release.

For each value state there is a alarm setting group that allows you to:

• Enable/disable the send of TRAP.
• Send TRAP only when the alarm state happens.
• Send TRAP only when the alarm state re-enters .
• Send TRAP when the alarm state happens or re-enters.

As you can see from the menus above, the operation mode is adjustable.

TRAP sending

The telemetry system is capable to sending TRAP up to five different addresses. Different addresses can be set using the OID in major MIB, in this case:

• IP address.
• Destination port.

Commands sending

Similarly to readings and settings of the measurements, the commands have a set of OID that are only in writing mode. For each transmitter, the MIB exports a specific set of OID.

The controls can regulate ON/OFF: to activate (ON) the user must send a “2” as value for the disabled (OFF) the user must send a “1” as value. No other values are accepted as a command. Usually the commands are one-shot toggle. In other words, if the transmitter is turn “ON” (value “2” to set-transmitter-on- 10ksd), the next command is a turn “OFF” (value “2” set-transmitter-off-10ksd ) and not a disable “ON” (value “1” to set-transmitter-on-10ksd).

Proxy Serial Communication

• There are a set of OID that monitoring the serial communication between the ANTLAN SNMP card and the Main card equipped inside the telemetry unit.
• The user can set the system so that all measures are sent to 0 when the serial communication fails. In this case is also issued a TRAP.

TRAP settings:
