DMD2050E Universal Satellite Modem User Interfaces

4.4.6.6 SNMP (menu)

A description of OID organization is provided in the MN-DMDREMOTEOP manual.

SNMP MENU SNMP VERSION {V1 & V2, V3} This selection controls the SNMP Version that will be used in

messaging between the equipment and it’s host. When V1 & V2 is used, RD COMMUNITY and RDWR COMMUNITY are used to determine the authorization of an incoming message. When V3 is used, three contexts are supported:

dev

. Context, Authentication and Privacy are a portion of each

SNMPV3 message.

public

The unit. This is the most restricted access possible and only allows the unit to be identified by a host SNMP Station. The access the mib2 OIDs and the SNMP OIDs. These are of interest primarily to network operators not controlling the satellite link. The access the device control portion of the MIB. These OIDs are used to control the devices satellite link and operation.

TRAP VERSION {V1, V2} This controls the type of message format used when a message

trap is generated by the equipment and bound for a SNMP Host. Messages will only be sent if the unit has been authorized to do so.

AUTHORIZATION {TRAPS OFF, TRAPS

ON}

RD COMMUNITY {16 characters of

name}

RDWR COMMUNITY {16 characters of

name}

TRAP AGENT {XXX.XXX.XXX.XXX}

Hexadecimal Mask {ddd.ddd.ddd.ddd} Decimal Mask

This controls the type of message format used when a message trap is generated by the equipment and bound for a SNMP host. Messages will only be sent if the unit has been authorized to do so. This menu is only displayed when SNMP VERSION is set to V1 & V2. This is the community that a host must be acting within when an OID variable is requested by a V1/V2 SNMP message. This menu is only displayed when SNMP VERSION is set to V1 & V2. This is the community that a host must be acting within when an OID variable is being changed by a V1/V2 SNMP message. IP address of the device receiving SNMP Traps

DMD2050E Universal Satellite Modem Theory of Operation

 Modem Status, Alarms & Contact Closures (Section 3.2.9)

3.2.6 Terminal Port

This port supports an asynchronous control protocol as described in Chapter 4. It is configured to support RS-232 signal levels. This port is intended for use in computer-based remote M&C. All functions of the modem may be monitored and controlled from this port via a common terminal connected to the Terminal Port. This function is front panel selectable.

The Terminal Mode Control allows the use of an external terminal or computer to monitor and control the modem from a full screen interactive presentation operated by the modem itself. No external software is required other than VT-100 Terminal Emulation Software (e.g. “Procomm” for a computer when used as a terminal. The Control Port is normally used as an RS–232 Connection to the terminal device. The RS-232 operating parameters can be set using the modem Front Panel and stored in Non-volatile memory for future use.

IMPORTANT Refer to the Remote Protocol Manual (MN-DMDREMOTEOP) for the Terminal, Remote and SNMP screens and protocols.

3.2.7 Modem Remote Communications (RLLP)

The Remote Port located on J20 allows for control and monitoring of parameters and functions via an RS-232 Serial Interface, or RS-485 for RLLP Protocol. ‘Equipment Remote Mode’ setup can be entered from the front panel or the Web Browser interface under the “System” menu. This requires the user to first set the Remote Port Control to “Remote” then set the Multidrop Address as needed followed by setting the Remote Interface to RS232 or RS485.

Control and status messages are conveyed between the modem and all subsidiary modems and the host computer using packetized message blocks in accordance with a proprietary communications specification. This communication is handled by the Radyne Link Level Protocol (RLLP), which serves as a protocol ‘wrapper’ for the remote M&C data. See the MNDMDREMOTEOP manual for more information.

Electrical Safety

The DMD2050E has been shown to comply with the EN 60950 Safety of Information Technology Equipment

(including electrical business machines) safety standard.

The unit is rated for these nominal operating ranges:

• 100 - 240 volts AC nominal operating range

• 48+/-5 volts DC nominal operating range for a correctly-equipped DC option

• 250 watts maximum power consumption

Battery

if the battery is incorrectly replaced. The

unit contains a Lithium Battery.

Replace the battery with the same or equivalent battery as recommended by the manufacturer.

Dispose of used batteries as required by local and national regulations.

Grounding

In Finland: "Laite on liitettävä suojamaadoituskoskettimilla varustettuun pistorasiaan."

In Norway: “Apparatet må tilkoples jordet stikkontakt.”

In Sweden: “Apparaten skall anslutas till jordat uttag.”

Fuses

The DC unit does not have fuses.

The AC unit requires two common, 2-Amp/250 volts, 20mm x 5mm Slo-Blo

of the unit, inside the power connector, behind the small plastic cover.

Always make

sure the ground stud on the rear panel of the unit is connected to protective earth.

Correct grounding protection helps prevent personal injury and equipment

damage.

: Always replace the fuses with the correct fuse type and rating. Use

correct fuses to help prevent damage to the equipment.

CAUTION:

ACHTUNG:

Preface MN-DMD2050E

Environmental

Do not operate the DMD2050E in an environment where the unit is exposed to extremes of temperature

outside the ambient range 0 to 50°C, precipitation, condensation, or humid atmospheres above 95% RH,

altitudes (un-pressurised) greater than 2000 metres, excessive dust or vibration, flammable gases, corrosive

or explosive atmospheres.

Operation in vehicles or other transportable installations that are equipped to provide a stable environment is

labor required to diagnose the necessity for repair or replacement.

The warranty excludes any responsibility by Comtech EF Data Corporation for incidental or consequential damages arising from the

use of the equipment or products, or for any inability to use them either separate from or in combination with any other equipment or

products.

A fixed charge established for each product will be imposed for all equipment returned for warranty repair where Comtech EF Data
