IGS-924 24 DVB Tuner to IP-Out  
Introduction:  
The BLANKOM IGS-924 is a high performance and cost-effective SPTS or MPTS IP streamer.  
Equipped with 24 DVB-S/S2x FTA (Free to Air unencrypted) tuner inputs, with BISS de-scrambling capabilities,  
up to 2x 512 SPTS Stream channels through Gigabit Ethernet ports (parallel operation as redundant stream-  
I/O). Depending on the chosen mode, the device can operate in SPTS (IPTV) Mode or 2x12 pass through MPTS-  
Mode (DVB over IP) by selecting it (device need to reboot after changing).  
To meet customers’ various requirements, this device is also equipped with 1(2) ASI input port which selected  
services can be streamed to the Gbe output. The ASI out are only used in MPTS mode.  
The BLANKOM IGS-924 is also characterized with a high integration level, high performance and very cost  
effective. This streamer is very adaptable to new generations of IPTV headend systems i.e., in hospitality  
environments serving FreeToAir (FTA) content and BISS encrypted Services.

New Front IGS-924C (V3):  
With LCD and keypad for basic information’s: E.g.: IP address of NMS -port will be shown per default.  
To access the device, press the LOCK-button first than you can use Menu/Enter and Arrow keys.  
Difference to the old IGS-924 Version: The Power-Button is now at the Front, 1 more ASI-IN port – which can  
be used for Streaming demultiplexing as well as USB- TS-Player:  
The rear panel has different Tuner now with Loop outputs. These should only be used looping if you are  
staying on the same SAT-polarization and same Low- or High band as the one you are looping from first.  
Example: Tuner 234 are looped starting with Tuner 1:  
All are in the same Low band (22KHz=Off) and using horizontal (18V): So only Tuner 1 need to tell the RF-  
Source (SAT-Multiswitch): The 18V DC must be switched ON, the other 3 do not need to switch it on and can  
stay OFF (0V).

CATV / DVB-C LOOPINGs:  
We recommend not to loop more than 3 times (same for SAT tuner) and use an external splitter  
with a pre-installed Amplifier to give the receiver – tuner inputs normed/measured levels. For long  
coax cables please also consider the slope correction in the amplifiers to compensate the  
attenuations in higher frequency ranges.  
Safety and other recommendations:  
Assure climatic environment rules for electronic machines like this, Grounding rules as well.  
Installation should be done by a certified electrician.  
Caution:  
Before connecting power cord to Tuner to IP Gateway, you should set the power switch to “OFF”.  
Do not connect the RF-cable (F-plugs) when the unit is running.

Installation Notes  
All types of the IRENIS-BLANKOM family are 19“devices with 1 RU height designed for installation in 19”  
racks. In addition to the front panel screws, an internal module support is required at the rack.  
Depending on the Frontend used and the operating adjustments, the RF-input port carries  
DC Voltage (13V /18V, max. 400 mA).  
By connecting a mains cable, the device can become functional without any auxiliary appliances. The power  
supply units are almost (! Please check rear) designed for the wide range of 100-230V AC, 50/60Hz; a  
manual adjustment of the voltage is not necessary.  
For some models, the second power connector is feeding another independent power supply for internal  
redundancy. For a maximum of redundancy, both power supplies should use different circuits.  
All the outputs are decoupled from one another. Thus, the circuit does not have any effect on the functioning  
of the device. Connections that are not required need not to be terminated.  
Suggestion: CAT 6E Ethernet cable for Gigabit-Ethernet  
Note:  
Ipv4 global scope sessions use multicast addresses in the range 224.2.128.0 – 224.2.255.255 with SAP  
Announcements being sent to 224.2.127.254 Port 9875 (note that 224.2.127.255 is used by the obsolete  
SAPv0 and MUST NOT be used).  
Ipv4 administrative scope sessions using administratively scoped IP multicast. The multicast address to be  
used for announcements is the highest multicast address in the relevant administrative scope zone.  
For example, if the scope range is 239.16.32.0 – 239.16.33.255, then 239.16.33.255 is used for SAP  
Announcements.  
Quick-Start Installation:  
The user can control and set the configuration of the device with any computer by connecting to the web  
server-Interface (WebIF) by the 100BaseT NMS Port. The user should ensure that the computer’s IP address is  
different from other device’s IP address; otherwise, it might cause an IP conflict. Be sure to set it in the same  
network range.

Usually, the device will be shipped in MPTS mode (BYPASS) and the config-Menus are logically  
different in SPTS and MPTS  
Please select the operating mode for SPTS (default) or MPTS in the Firmware section:  
Bypass means MPTS 1:1 transponder to IP stream  
output  
Note:  
If you change the SPTS mode to MPTS (and vice versa) you need to backup your settings before the change. It  
doesn’t accept the previous saved settings from the SPTS or MPTS mode because they are different. Sounds  
logical, isn’t it?  
Just to show the difference for MPTS – outputs – only 24 IP streams can be assigned. You should decide  
whether a stream goes through GbE DATA1 or DATA2 so please balance the MPTS streams if more than 800  
Mb/s are to be streamed.  
Manually reboot is needed if you switch the modes ByPass MPTS <-> SPTS and maybe better to safe the  
config first to external file on a PC…

Check whether you want to parse the CBR-stream which includes the PID8191 Zero packets for the  
Constant Bitrate or w/o Zeros as VBR-Stream:  
IMPORTANT:  
Do not use the default IP settings for the  
UDP/RTP multicast streams. At least  
increase the IP numbers. Otherwise, your  
connected L3 IGMP switch will pass all  
streams with same IP address. The Port No  
should  
be  
also  
different.  
E.g.:  
225.1.1.1:10000, next 225.1.1.2:10002, …

No PID8191dec = no Zero packets

Network Setup:  
We assume that the user is familiar with IP settings and already knows his own system to connect the unit to.  
If you use the Output Streaming: We recommend using 2 separate Switches for MNS and Streams! Attention:  
The Switch must support IGMP Filtering to not overload the NMS 100 baseT port  
At least a 100BaseT for the Management NMS RJ45 port and a second one with Gigabit Ethernet  
10/100/1000BaseT with at least Layer 2+ with IGMP V2 features. Otherwise, you might flood your IP-Streaming  
network with unnecessary Data, which might overload connected IPTV STB's because they almost have only  
100BaseT capacity (Never ones use 1GbE ports) but too many inputs into a STB can result in side effects. If you  
need to select a Switch, we recommend HP Procurve 2530 24G or 48G which are cost effective, easy to  
configure, can be trunked and supporting IGMP V2. If the switch needs routing functions, the bigger brother of  
this series might be the right choice.  
Because to not accidently put DATA and NMS port in the same sub-network, the data – port setting does not  
allow this by default. Usually, the DATA GbE Ports needing at least own and free IP addresses- otherwise the  
Switch or the receivers (i.e., IPTV STB's) cannot locate the source of the streams.  
Note: DATA1 and 2 are handled by the same Network-hardware and is addressed as (Linux users  
know that):  
eth1 and eth1.1  
So, they are not fully independent but should work independently. But please assure different IP  
addresses and avoid network conflicts.

Changing a user-account:  
Change it to your needs, but do not forget the password otherwise you would need to reset the unit with the  
Front-panel RESET switch (If this model has one, press it min. 10…15 sec) to factory default.  
ATTENTION: Do not use 'special' characters like @ or % or &… for the username and the  
password because you will be locked out. These are not accepted by the basic installed character  
table for it.  
Set Date and time as NTP:  
Tuner-Setup:  
Note: DVB-C / T Tuning is slightly different and you need to enter the center- frequency of the to be  
received DVB-C/QAM channel. The tuner will detect the inside-channel values.  
NOTE: a comma in the frequency like 624,25 MHz has to be entered in AMERICAN STYLE as a ‘.’  
Instead the ‘,’  
So, we do concentrate on Satellite first:  
Basics:  
We recommend to connect every tuner RF Input to the L-Band network by  
-Using a Multiswitch with more than one SAT-position and > 16 SAT-IF outputs: You can set every  
single Tuner Input individually.  
-Using a SAT-Splitter: Be carefully, active splitter needs at least one 13V…18V DC connection to it to  
operate. You should avoid to switch on V/H polarization Voltage 13/18V on every Input port. The  
active splitter would pass the 13V or 18V to the Multiswitch and assigning the fixed polarization to  
the Multiswitch. So, all selected Transponders should be either in Vertical (13V) or Horizontal (18V)

position.  
Passive splitters should be used with DC Passthrough and the Voltage should be passed only once  
as well.  
We recommend to check www.lyngsat.com or www.satbeams.org for correct settings.  
Example:  
LOW-Band =9750 MHz LNB-IF frequency - while  
HIGH-band = 10600.000MHz using 22KHz signal

Example ASTRA Satellite (is DiSEqC port A (1) at our Multiswitch): satindex.de - ASTRA  
You see 4 of 8 are encrypted and cannot be decrypted by this FTA receiver.:  
Entering its values: Transponder Frequency: 10964 , Low band LNB-IF=9750, 22000 KS/s, 18 V = Horizontal,  
22KHz High band switching = OFF because we are in low Band (border is 11700 MHz)  
Please be patient, the tuners need to swing into it and it takes a moment until the web-IF shows
