Type HDA-4510
1.485 Gb/s HD 6 O/P
Reclocking Distribution Amplifier
General Description
The HDA-4510 1.485 Gb/s serial digital video reclocking distribution amplifier provides the user with a single
standard module to cover a wide range of distribution and monitoring functions for High Definition (HD) digital
signals.
As well as accepting an HD signal, the HDA-4510 will also accept Standard Definition (SD) rates such as SDI. ASI
is also possible, however as three of the six outputs are inverted only the non-inverted output ports are suitable for
ASI.
Serial digital signals suffer severe deterioration over relatively short cable distances. This is especially so with the
HD high data rate. The HDA-4510 provides a means of extending the working distances that can be achieved by
equalising and re-transmitting the data mid route.
The HDA-4510 will automatically reclock either a 1.485 Gb/s HD signal or a lower rate SD signal and automatically
adjust the output driver slew rate to suit.
Front panel LEDs indicate when an input signal is present and also whether it is either an HD or SD type of signal.
A relay alarm output, with a selectable N/O or N/C switch to ground contact, is available for indication of loss of
input signal or loss of power.
An optional SNMP (Simple Network Management Protocol) plug in module is available for remote monitoring when
used in conjunction with IRT’s 4000 series frame fitted with SNMP capability.
The HDA-4510 is designed to fit IRT’s 4000 series frame for use with IRT’s SNMP system as well as being suitable
with IRT’s Standard 1000 and 3000 series Eurocard frames and may be used alongside any other of IRT’s analogue
or digital Eurocards.
Standard features:
• Automatic selection of either High Definition or Standard Definition digital signals
• 6 reclocked outputs
• Automatic input equalisation
• Locked signal presence LED and external relay alarm contact
• Optional plug-in SNMP monitoring module

Installation
Pre-installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling precautions
should be observed.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Power:
AC mains supply: Ensure that operating voltage of unit and local supply voltage match and that correct rating fuse
is installed for local supply.
DC supply: Ensure that the correct polarity is observed and that DC supply voltage is maintained within the
operating range specified.
Earthing:
The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure that
the frame is connected to earth for safety reasons. See frame manual for details.
Signal earth: For safety reasons a connection is made between signal earth and chassis earth. No attempt should be
made to break this connection.
Installation in frame or chassis:
See details in separate manual for selected frame type.
Digital Input and Outputs:
Input and outputs are all 75 ΩBNC type for connection with high quality 75 Ωcoaxial cable suitable for either
1.485 Gb/s high definition digital signals for HD use, or for 270 Mb/s standard definition signals for SD use.
Ensure that links settings are correctly set for the mode of operation required as described in the Configuration
section of this manual.
Alarm Output Connection:
A normally open, or normally closed, 2-pin connector is provided on the rear assembly for an alarm connection on
loss of signal input or loss of power. Pin 1 is permanently tied to ground. During an alarm condition an on board
relay contact either shorts or open circuits pin 2 to/from ground dependent on the position of link LK7, as described
in the Configuration section of this manual.
Front Panel Indicators:
Front panel LED’s indicate the presence of an input signal (SIG – Green); whether the input signal is an HD signal
(HD – Green) or an SD signal (SD – Yellow); and the presence of power to the module (DC – Green).

SMU-4000 Installation
The SMU-4000 plug-in SNMP management controller module can only be fitted to IRT’s 4000 series modules that
are capable of being SNMP upgradeable. To determine whether a module is SNMP upgradeable, a square section on
the main PCB is silk screened and fitted with three multipin sockets – as shown below:
This is where the SMU-4000 plug-in SNMP management controller module is fitted. The three sets of multipins on
the underside of the SMU-4000 line up with the three sets of multipin sockets on the main PCB module. Align all
pins and then gently press the SMU-4000 all the way down into place.
If the SMU-4000 is not already programmed with the correct firmware to match the module that it is being plugged
into, it then needs to be programmed via the pins on the topside of the SMU-4000.
Note that installation will generally be done by IRT Electronics at the time of ordering.
Note also that an SMU-4000 will only be functionally operational when the main module that it is plugged into is
fitted into an IRT 4000 series frame fitted with a CDM-4000 SNMP agent and being interrogated by a suitable
Network Management System.
HDA-4510 SNMP Functions:
With the HDA-4510 installed in an IRT 4000 series frame with SNMP capability, the HDA-4510 can be interrogated
by an SNMP Network Management System (NMS).
The following SNMP functions are capable of being monitored by an NMS:
An indication that an input signal is present;
An indication of the current state of the Urgent Alarm;
Trap automatically sent, if enabled, when an Urgent Alarm occurs or is restored;
Unit reset control.

SNMP
What Is It?
SNMP stands for Simple Network Management Protocol. It is an application layer protocol for managing IP
(Internet Protocol) based systems. SNMP enables system administrators to manage system performance, and to find
and solve system problems. SNMP runs over UDP (User Datagram Protocol), which in turn runs over IP.
Three types of SNMP exist: SNMP version 1 (SNMPv1), SNMP version 2 (SNMPv2) and SNMP version 3
(SNMPv3). It is not the intention here to discuss the differences between various versions, only to bring attention to
the fact that IRT Electronics modules, fitted with SNMP capability, use SNMPv1.
An SNMP managed network consists of three key components: Network Management Systems (NMS), agents, and
managed devices.
An NMS is the console through which the network administrator performs network management functions, such as
monitoring status (e.g. alarm states) and remote controlling, of a set of managed devices. One or more NMSs must
exist on any managed network. Generally the NMS is a computer running third party SNMP control software. There
are a number of third party SNMP software applications currently available on the market.
An NMS polls, or communicates with, an agent. An agent is a network management software module that resides in
a managed device. An agent has local knowledge of management information and translates that information into a
form compatible with SNMP. The agent, therefore, acts as an interface between the NMS and the managed devices.
The NMS sends a request message, and control commands for the managed devices, to the agent, which in turn sends
a response message, containing information about the managed devices, back to the NMS.
A managed device contains an SNMP agent and resides on a managed network. Managed devices collect and store
management information and make this information available to NMSs using SNMP.
Managed device agent variables are organised in a tree structure known as a Management Information Base (MIB).
Within the MIB are parameters pertaining to the managed device. An Object Identifier (OID) number within the MIB
defines the managed device type. This is a unique number specific to the model of managed device. Other
information relating to the device is also stored, information such as alarm states, controllable settings, etc. The MIB
tree is organised in such a way that there will be no two MIB files with conflicting placements.
Normally an NMS polls an agent for information relating to the MIB in a managed device to be sent back to the
NMS. When certain conditions are met within the MIB, such as major alarm conditions, for example, the agent
automatically sends what is known as a trap to the NMS without any prompting from the NMS. This allows automatic
notification of a predetermined event.

SNMP with IRT Products:
IRT Electronics currently employs SNMPv1 with its 4000 series frame. The frame acts as an agent when fitted with
a CDM-4000 module. This module has its own designated slot next to the power supply so as to not affect the
number of modules that the frame will take. Communication between the NMS, the frame and its loaded modules are
via this CDM-4000 module. Note that the NMS software is third party and not supplied by IRT Electronics.
Ethernet connection for SNMP operation is via an RJ45 connector on the rear of the frame, below the mains inlet.
Ethernet rate runs at either 10 baseT or 100 baseT.
Frame parameters, such as Name, Address and Location, are set via an RS232 interface, a D9 connector on the rear
of the frame below the mains inlet. A software terminal emulator, such as Tera Term or HyperTerminal, is used for
setting and reading the parameters of the frame.
IRT modules that are SNMP compatible need a plug-in SMU-4000 module with a program relevant to the module
that it is plugged into. Depending on the module, besides the module identification, parameters such as alarm states,
inputs and controls etc. are communicated to the CDM-4000 agent via a data bus on the rear of the frame. Thus the
CDM-4000 collects information on what is loaded within the frame, what positions they occupy, and their current
status for communication to the NMS when the NMS sends a request for information.
In the event of a major alarm from any of the SNMP compatible modules, or power supplies, a trap is automatically
sent by the CDM-4000 agent to the NMS without any prompting by the NMS. This alerts the operator to any fault
conditions that may exist that need immediate attention.

No regular maintenance is required.
Care however should be taken to ensure that all connectors are kept clean and free from contamination of any kind.
This is especially important in fibre optic equipment where cleanliness of optical connections is critical to
performance.
Storage:
If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed
plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be
included to deter corrosion.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Warranty & Service
Equipment is covered by a limited warranty period of three years from date of first delivery unless contrary
conditions apply under a particular contract of supply. For situations when “No Fault Found” for repairs, a
minimum charge of 1 hour’s labour, at IRT’s current labour charge rate, will apply, whether the equipment is within
the warranty period or not.
Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on
components shall be extended by IRT only to the extent obtainable from the component supplier.
Equipment return:
Before arranging service, ensure that the fault is in the unit to be serviced and not in associated equipment. If
possible, confirm this by substitution.
Before returning equipment contact should be made with IRT or your local agent to determine whether the
equipment can be serviced in the field or should be returned for repair.
The equipment should be properly packed for return observing antistatic procedures.
The following information should accompany the unit to be returned:
1. A fault report should be included indicating the nature of the fault
2. The operating conditions under which the fault initially occurred.
3. Any additional information, which may be of assistance in fault location and remedy.
4. A contact name and telephone and fax numbers.
5. Details of payment method for items not covered by warranty.
6. Full return address.
7. For situations when “No Fault Found” for repairs, a minimum charge of 1 hour’s labour will apply,
whether the equipment is within the warranty period or not. Contact IRT for current hourly rate.
Please note that all freight charges are the responsibility of the customer.
The equipment should be returned to the agent who originally supplied the equipment or, where this is not
possible, to IRT direct as follows.
