Installation Guide
General Precautions
Must be operated and maintained free of dust or dirty environments
The chassis should be securely fastened, do not open the top case of the
product when power is on.
After use, securely stow away all loose cables, external antenna, and others.
Power Precautions
When you connect the power source, assure correct grounding
Make sure the power switch is off before you start to install the device
The Device Installation Flow Chart is Illustrated as following:
Environment Requirement
Item
Requirement
Machine Hall Space
When user installs machine frame array in one machine hall, the distance
between 2 rows of machine frames should be 1.2...1.5m and the distance
against wall should be no less than 0.8m.
Machine Hall Floor
Electric Isolation, Dust Free; Volume resistivity of ground anti-static
material: 1X107...1X1010，Grounding current limiting resistance: 1M
(Floor bearing should be greater than 450Kg/㎡)
Environment
Temperature
5...40°C (sustainable )，0...45°C (short time)，
air-conditioning is recommended
Relative Humidity
20%...80% sustainable 10%...90% short time
Pressure
86...105KPa
Wall
It can be covered with wallpaper, or brightness less paint.
Fire Protection
Fire alarm system and extinguisher
Power
Device power, air-conditioning power and light power should be
independent to each other. Device power requires AC 110V±10%, 50/60Hz
or AC 220V±10%, 50/60Hz. Please carefully check before installing.
Grounding Requirement
Sufficient grounding is the basic of reliability and stability of such devices. Also,
they are the most important guarantee against lightning and interferences.
Grounding conductor must be installed with copper conductor in order to
reduce high frequency impedance, and the grounding wire must be as thick and
short as possible.
Users should make sure the 2 ends of grounding wire well electric conducted

It is prohibited to use any other device as part of the grounding electric circuit
The area of the conduction between grounding wire and device’s frame as
19'' Racks should be no less than 25 mm2.
Management by Web-Interface (WebIF):
The user can control and set the configuration of the device with any computer by connecting to
web 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.
Default Login-Data on 192.168.0.136 (default factory address) are admin/admin:
Language and feedback according to your used OS.
This unit is equipped with 2x 4 HDI-Input port modules. The HDM 8512 C (or T) has 3 Modules
installed. So all configurations are similar Module by Module.
The STATUS page gives an overview of System information HW/SW Versions …. Left frame is the
menu-panel to select the different sub-menus. PARAMETER Submenu: You are seeing the Input
Module 1 … 3, DVB-C Tuner, ASI IN (Option) , TS-configuration for the outputs, Encryption (Scrambler
setup) DVB-C Output (4 ch), OSD overlay feature setup. And SYSTEM setup.
We start with the Network settings of the NMS- management port:
We assume that the user is familiar with IP settings and already knows his own system to connect the
The user can select any item here to enter
the corresponding interface and sub-menu to
check information or set the parameters.

unit to. We recommend using 2 separate Switches: 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.
The scrambler Port is the
same RJ45 connector like the
NMS Management port. But
needs its own IP address.
By default and security issue,
it cannot use the same subnet
range like the NMS port.
Same is done for DATA1 GbE
Port and DATA2 GbE Ports
where Streams can be sent IN
and OUT.

Save and Restore the configuration:
We highly recommend to safe the configuration to be able to restore it at all time just in case
the unit was accidently w/o power or any other interruptions happened.
This method is only temporary so we recommend to use the Backup and Load function instead:
Safe/Store the config.bin file on your
local PC.
