IDC Satellite Receivers

The SR2000pro


Since 1984, International Datacasting Corporation (IDC) has been a recognized market leader in the point-to-multipoint distribution of broadband multimedia content over satellite. IDC is publicly traded on the Toronto Stock Exchange (TSX:IDC).

 International Datacasting Corporation (TSX: IDC) is a global leader in digital content distribution for the world’s premiere broadcasters in radio, television, data and digital cinema. IDC offers a broad portfolio of advanced solutions including Pro Audio, Pro Video, Pro Cinema, and Pro Data for implementing broadcast content contribution and distribution applications. IDC’s products and solutions are in demand for radio and television networks, digital cinema, 3D live events, targeted ad insertion, satellite news gathering, sports contribution, VOD, and IPTV among others. IDC is head quartered in Ottawa, Canada, with regional offices in Arnhem, the Netherlands and in San Diego, California. IDC has installations in over 100 countries and service offices in Thailand and Singapore, with an international network of value-added partners and resellers.
In New Zealand  there are many commercial and non commercial radio stations that use IDC products to transit their program material from their broadcast studios to remote single or multiple transmitter sites and to capture and insert program material from outside providers, such as news bulletins, sports events, advertising and the likes.
This page is going to deal with the International Datacasting Corporation (IDC) SR2000pro.
The SR2000pro is found in IDC's Superflex, FlexRoute IP Pro Audio Suite For Professional Radio Broadcast Networks, publication.
In those receivers listed are the SR2000pro - SR for Satellite Receiver - 2000 for the model series and - pro for Professional Audio or could equally be for Program Audio.
The Pro or Pro Audio receivers have inbuilt audio decoders which output a Balanced Audio Signal from connectors on their rear panels, ready for insertion into the Broadcast Station's RF Exciter or RF Transmitter.
Some receivers also have the Plus (suffix). Receivers with the Plus (suffix) have unbalanced audio output.
The SR2000pro uses mini XLR sockets on the rear panel to feed out Balanced Audio from its inbuilt decoder. The SR2000pro has two audio output channel streams, each outputting audio in stereo. Each channel stream has a left and a right stereo output socket (Mini XLR) and a AES output socket (Mini XLR). Consequently there are three output sockets per channel stream, a total of six sockets for the two channel streams.
Some models, instead of having stereo output, have quad mono Balanced Audio output sockets.
The SR2000pro is only produced in one case size which is (1U) or (1RU) = single Rack Unit Size - single height. As a consequence the case size is not referred to in the model number.

The SR2000pro has non removable XPC860PZ80D4 Processor which is a 32 bit processor that can operate up to a speed of 80 MHz. This is located on the Main Board near the Flash Memory card. It does not have any heat sink. The Main Board has two RAM chips which are non removable. They are 48LC16M16A2 which are PC133 compliant, 16 MB each, giving a total of 32 MB of RAM
Listed below are the range of receivers in IDC's Superflex, FlexRoute IP Pro Audio Suite For Professional Radio Broadcast Networks, publication. Other receivers are referred to here as the SR2000pro  shares some of its specifications with other receivers in the Superflex, FlexRoute IP Pro Audio Suite .

DVB/I P DIGITAL AUDIO RECEIVER


IDC SR2000pro Picture


The SR2000pro is the newest addition to IDC’s family of professional DVB audio receivers. Drawing from our highly functional and proven reliable DVB/IP satellite receivers,we have added exciting new features to create the SR2000pro.

• fully DVB compliant

• 256ks/s to 45 Ms/s for full carrier
range

• 10/100 Base-T Ethernet output (RJ-45)

• FlexKey system encryption for
data security

• web browser based status and
control

• remotely manageable over satellite
and/or terrestrial networks

FINALLY, a professional audio
over IP solution

• two built-in stereo audio
decoders

digital audio

• balanced audio outputs

• all the MCPC advantages of DVB

• ideal for professional audio networks


Extended Carrier Range – Operates on carriers ranging anywhere from 256ks/s to 45Ms/s. For use on DVB shared service uplinks and/or simple enough to operate as a standalone uplink. At 256ks/s (the lowest in the industry) it’s easy to save on the cost of bandwidth—the most expensive component of any data network— and grow as your business grows.

Enhanced FlexKey Security – The SR2000pro features IDC’s own built-in FlexKey decryption, an affordable alternative to high-end encryption and conditional access systems. FlexKey is a flexible key encryption system allowing keys to be changed over the satellite, providing superior security and reduced cost of ownership compared to low-end receivers that use only fixed or no encryption key capability.

Enhanced Monitoring and Control – A browser based status and control GUI allows satellite carrier frequency, data rates, port authorization and other operating functions to be set locally or remotely. Terminal Interfacing facilitates easy local installation while receivers can be remotely controlled using IDC’s NetManager2 via the satellite network. This can occur either individually, in groups, or globally and/or using SNMP via terrestrial networks for monitoring and control. Metadata and relays
are user-controlled with IDC’s EventManager software.

AUDIO NETWORKS VIA IP MADE EASY - The SR2000pro features dual stereo MPEG audio decoders and IP based Forward Error Correction (FEC), making this receiver ideal for professional audio networks and hybrid systems combining digital audio with IP content delivery. The SR2000pro’s Ethernet port allows for store & forward distribution of audio files and associated data, as well as IP streaming of audio to a remote LAN.The SR2000pro provides all of the advantages of DVB multichannel per carrier (MCPC) operation in a receiver designed to accommodate the needs of audio networks.

DVB OPERATION MADE EASY- IDC’s SR2000pro, along with other components from our proven SuperFlex and Datacast XD product lines make it easy for professional audio networks to convert to DVB.The SR2000pro is backed by IDC’s 20 years of experience with satellite networks, network management & control, as well as our tradition of making innovative, professional-grade products for the radio broadcast industry.

Below are photographs of the internals of the SR2000pro

IDC SR2000pro Internal View

The picture above shows the combined Satellite receiver board and Processor board on the left. On the upper right is the audio decoder board which also has the relays (white components), four for each audio channel stream. To the lower right is the front panel control board.

IDC SR2000pro Main Processor Board

The picture above shows the SR2000pro combined Satellite Receiver and Main Processor Board. Four cables connect to the board, 1 for power supply to the Front Panel Control Board (lower right), 1 for front panel LEDs (upper left ribbon cable) 1 FDD style cable (takes data to Audio Decoder Board) and one ribbon cable (upper right) that also connects to the Audio Decoder Board). Note that this picture has a looped cable at upper left which is not standard. This cable is connecting a damaged Net Port (Ethernet) socket to an external corded socket. Note that there are a number of connector sockets that do not have cables connected to them. The processor speed on this board is 70 MHz.


IDC SR2000pro Audio Decoder Board


The picture above shows the SR2000pro Audio Decoder Board. On the left is the FDD style ribbon cable which connects to the Main Board. On lower right is the ribbon cable that connects to the Main Board near the front of the unit. The two ribbon cables at the top of the picture connect to the two 9 pin male DB9 connectors on the rear panel. The two DB9 connectors provide unbalanced left and right audio outputs for each channel stream.

IDC SR2000pro Front Panel Control Board

The above picture shows the Front Panel Control Board which has the LCD panel and the set up button pad on the other side. The ribbon cable on the left goes to Display connector toward the rear of the Main Board. Note there are four connectors which do not have any cable connections to them.


IDC SR2000pro Main Board Memory Card

The above picture is of the SR2000pro 32MB Compact Flash memory card that is on the Main Board. This memory card contains the software (Linux, Apache & XD client) that loads when the receiver is powered up. Note this machine does not have a hard drive.

IDC SR2000pro Rear Panel


The above picture is of the SR2000pro Rear Panel. The Channel 1 and Channel 2 Audio Stream connectors are toward the left. The lower Mini XLR connectors provide Balanced left and right outputs for each channel. An AES connector is also included. The upper DB9 connector provides Unbalanced left and right outputs for each channel. The Channel 1 and Channel 2 Relay Connectors are next to the Audio Output sockets and have screw up wire connectors. Near the centre is the Ethernet Net Port. Note that on this machine photographed, the Net Port suffered contact damage so a wired Ethernet connector has been fitted - that is the cable seen coming through the rear panel to the left of the Net Port. To the right are the Async Port, the L Band LNB Connector and the DC Power Socket.

The SR2000pro Power Supply.


The SR2000pro does not have an internal power supply but has a DC power socket on the rear panel of the receiver, toward the right side when looking at the rear panel of the receiver.
The receiver requires three voltages for operation. + (plus) 12 volts, + (plus) 5 volts, and - (minus) 12 volts. A common or GND (ground) connection is also required. The three voltages are measured in relation to the ground. The power supply that is supplied standard with the receiver from the factory, is similar in size and design to a power pack for a laptop computer - that is it has a mains power cord which supplies power to a rectangular shaped power pack and a cable from the rectangular shaped power pack has a cylindrical shaped DC plug which inserts into the Power Socket on the rear of the receiver.

Below is a picture of the DC Power Socket on the rear of the receiver. The picture is labelled with the voltages that are supplied to each pin of the socket.
IDC SR2000pro DC Power Socket Picture

Note that the two upper holes of the socket are wider spaced than the two lower holes. This feature is to ensure that the DC Power Plug can not be inserted in an other than the correct position. The plug also has a metal barrel around its outer edge, protecting its pins from coming into contact with foreign objects. That metal barrel of the plug inserts into the outer circular groove of the DC Power Socket and forms a second ground connection.


Improvising A Power Supply


Many times if you have purchased a receiver from a surplus trader, for one reason or another the trader does not have the power supply to go with the receiver. This leaves you having to hunt for an original or improvise.
A standard desk top computer power supply can be adapted to operate the SR2000pro. A length of cable with either 4 cores and a sheild (like the outer shield of coax) or  a five core cable is required. The correct plug to attach to the end of the cable is also required. These should be able to be purchased from an electronics store.

(To be continued)

Defeating The Passwords;


As radio stations and networks upgrade their IDC equipment to newer models, there are numbers of these older receivers becoming available second hand. Often they are sold by surplus equipment dealers who have no connection to the stations or networks that the receivers operated in and so do not know the passwords that have been set in the machines. Often these receivers have been in service till the day they are switched off and new equipment installed. The previous users have no interest in returning the passwords to factory default and neither do they provide the passwords with the used receivers. As a consequence the new owner is left to their own devices to defeat the passwords that have been set.

The IDC machines have two levels of passwords, monitor and admin. When logged into the receiver's setup as "monitor", activity is restricted to viewing settings only and does not allow changing of any settings. To change settings it is required to be logged in as "admin". As a consequence, the "monitor" login may only use a low strength of passwood or may use only the default password, but the "admin login" may have been set to a higher strength password. Without being logged in as "admin" it is not possible to edit settings in the control cockpit.

It is thought that the factory default password for the SR2000pro  may be 12345 so this is the first option to try. Other possible tries are admin, user and usr, login, abc, abcd, abcde - etc. If these are not successful then continue with the instructions below.

The Flash Card must be removed from the IDC machine so it can be inserted into a Card Reader adapter and connected to another computer. If using a computer running a Linux operating system, you have immediate access to files on the hard drive. If you have a computer running Windows, because Windows can not read Linux files, you must install a programme that enables the viewing and editing of Linux files. In this case, a program called DiskInternals Linux Reader 1.6.4.0
Once this program is installed and run on the Windows computer, the SFX Linux based Flash Card will be visible in the list of Drives.

It may show up as Linux Ext Volume 1. Below that in the list it may show Volume 1 and Volume 2 but they do not appear to be files that can be opened.

Note that the following procedure has not been done in practice but it is presumed it will work.

Open Linux External Volume 1 (if that is what shows on your computer) by double clicking on it and a number of Folders will be visible. Double click on the etc Folder to open it. Single click on the Shadow File to highlight it and then choose "Save As" and change the name of the file to "shadow-old" and save. This gives you a copy of the file in case you do something not intended to the file while changing it. Now double click on the "shadow-" file to open it for editing. Select All and choose delete. When the contents of the file are deleted then Copy and Paste the following to replace the contents of the file.

root:$1$nbi.g1p5$fokbTAI9fewfZYRPCq9DG0:12221:0:99999:7:::
apache:!!:11884:0:99999:7:::
admin:$1$CGk6QvYB$bSRqNVQs.7c8HxrCEZwEe/:11914:0:99999:7:::
monitor:$1$zoa4ztY9$C.UyWMVu41fEVLZeUFNm2.:12005:0:99999:7:::

Now choose save. If this has worked as planned it should have set the admin password to 12345.

Look also for a file named Shadow.bak which should also be in the folder called etc. If this file exists (it did not on the machine in this instance) then perform the same operations as above for the Shadow.bak file.

The following file called passwd file was found in the etc folder but the paths listed in the file did not exist
(it did not on the machine in this instance)

root:x:0:0:root:/root:/bin/sh
apache:x:48:48:Apache:/var/www:/bin/false
admin:x:500:500::/home/admin:/bin/admin_sh
monitor:x:501:501::/home/monitor:/bin/monitor_sh

This is mentioned for the point that if these paths exist on a machine it may also be of signifacance.
