AMS-4170T

2 x 2 relay switcher

for SDI, G.703 or analogue video

AES, RS422 or stereo audio signals

General Description

The AMS-4170T consists of one “video” and two “balanced audio” switches. Each switch is arranged as a

changeover set with two inputs and two outputs. No terminations are provided on the board allowing the switcher to

be used in a wide variety of applications and with signals of various types and impedances.

The “video” path uses enhanced performance relays to provide switching capabilities for high-speed data signals up

to 270 Mb/s and may be used with analogue video, SDI, MPEG or RF signals. When used with SDI and high-speed

data signals all cable lengths should be kept to a minimum. For best performance the outputs should be connected to

inputs with automatic cable equalisation.

The “audio” path may be used for balanced or unbalanced audio or control signals (RS232, RS422, RS485 etc).

The AMS-4170T is ideally suited to applications where a simple choice between two inputs or outputs is required

and may be easily driven by audio, video or other detector circuits for automatic path selection.

Each switch is equipped with its own transistor driver circuit, which may be bypassed for direct operation of the

relay if desired. Links allow any of the three driver circuits to operate more than one of the sets of relays.

Front panel LED indicators are used to indicate the status of each relay circuit.

Front panel switches allow a choice of local or remote control operation.

An optional SNMP (Simple Network Management Protocol) plug-in module is available for remote monitoring and

control when used in conjunction with IRT’s 4000 series frame fitted with SNMP capability.

The AMS-4170T is designed to fit IRT’s standard Eurocard frames as well as IRT’s 4000 series frame for use with

IRT’s SNMP system and may be used alongside any other of IRT’s analogue or digital Eurocards.

Standard features:

• One video and two balanced audio changeover switches in one package.

• Video path suitable for SDI (270 Mb/s), analogue video, MPEG data streams @ 2, 8, 34, 45, 144 Mb/s.

• Audio path suitable for 2 balanced audio or data signals or 4 unbalanced audio or data signals.

• Married or independent operation

• Default path on power fail.

• Local or remote control.

• Optional plug in SNMP monitoring and control module.

• Front panel LED status indicators.

Configuration

Transistor drive to relays:

The AMS-4170T comes standard with links LK2, 4 & 6 installed. This allows TTL logic to directly drive the relays

via transistor drive circuits. It is not necessary to use TTL logic to drive the transistor drive circuits, however,

grounding on the control port is all that is needed.

Direct drive to relays:

Provision has been made for bypassing the transistor relay drivers if required. This may be desirable in situations

where switching is to be initiated by alarm circuits with relay outputs.

The relay driver circuit can be bypassed as follows:

1. Remove links LK 2, 4 & 6.

2. Hard wire shorting links in positions LK 3, 5 & 7.

Ensure that only one link is installed of each pair so that the circuit is set for either TTL or direct operation, but not

both.

Relay grouping:

Each video and audio channel is equipped with its own driver circuit. However each circuit is capable of driving all

three sets of relays if required. Links LK 8, 9 & 10 provide a means of inter-connecting the relay sets so that only

one or two control inputs are required.

Some useful configurations are:

Unison operation: All three circuits switch from one control signal.

1. Remove links LK 2, 4 & 6.

2. Connect links LK 8, 9 & 10.

3. Control is via SK 5 pin 1 to ground (SK 5 pin 4).

In order for the front panel switches to work as intended, AMS-4170T should be run in unison operation.

Separate video & stereo audio operation:

1. One control signal for video, and separate control signal for stereo audio.

2. Connect LK 9 & 10.

3. Control for video is via SK 5 pin 1.

4. Control for stereo audio is via either SK 5 pin 2, or SK 5 pin 3.

If controlling video and audio separately the front panel switches will only work on the video part of the circuit.

Input termination:

No terminations are provided on the module so that the switcher can function in changeover mode. For 2 x 1

switcher applications the following terminations should be installed.

Video: Output A only is used and should be terminated at connected equipment.

Output B should be terminated in 75 Ohms (or 50 Ohms if being used for 50 Ohm RF signals) using a BNC

termination plug.

Audio:

Outputs A only are used and should be terminated at connected equipment.

Output B may be terminated if desired by connecting termination resistors to the connector on the rear

assembly of the module. The resistor values should be chosen to match the characteristic impedance of the

rest of the connected audio system. For example for balanced 600 Ohms, two 300 Ohm resistors should be

used.

In most modern audio systems a low output impedance of approximately 40 Ohms and input impedances of

greater than 10 kOhms are used. If this is the case no termination of the unused audio output is required.

4170t-ams.ib.rev0.doc Page 6 of 14 17/10/2007

Operation

See Configuration section for relevant link settings.

Control connections:

Control connections are via SK 5 plug in screw terminating connector located on the rear assembly.

Connecting the appropriate control input to ground will cause the relays to operate and the output state to cross over

as follows: Control Input Output

High (or O/C*) A ↔ A

B ↔ B

Low (Gnd) A ↔ B

B ↔ A

Control input connector SK 5 pin configuration is as follows:

Pin Description

1 Video control

2 Left audio control

3 Right audio control

4 Gnd.

Note: * O/C = Open Circuit.

Front Panel Switches:

The AMS-4170T has two front panel switches – a local/remote switch and an activate/de-activate switch.

With the local/remote switch set to ‘remote’, the AMS-4170T behaves, and is controlled, as described above.

With the local/remote switch set to ‘local’, control connection via SK 5 on the rear assembly is bypassed. Control is

via the front panel activate/de-activate switch. Note that to fully function in the local mode, the AMS-4170T needs

to be run in unison operation as described in the Configuration section.

Note: SNMP control is disabled if the local/remote switch is set to local.

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.

AMS-4170T SNMP Functions:

With the AMS-4170T fitted with the optional plug-in SMU-4000 SNMP module, programmed with the firmware to

suit and installed in an IRT 4000 series frame with SNMP capability, the AMS-4170T can be interrogated and

controlled by an SNMP Network Management System (NMS).

The following SNMP functions are capable of being monitored and controlled by an NMS:

The current state of the Video switch state;

The current state of the Left Audio switch state;

The current state of the Right Audio switch state;

The current state of the front panel switches (relevant to AMS-4170T only),

Note: SNMP control is disabled if the local/remote switch is set to local;

A change of state to the Video switch (when changeover initiated by the

Video TTL control circuitry);

A change of state to the Left Audio switch (when changeover initiated by the

Left Audio TTL control circuitry);

A change of state to the Right Audio switch (when changeover initiated by

the Right Audio TTL control circuitry);

Whether “Trap” function is enabled; and

Trap automatically sent, if enabled, on change of switch state.

Installation

Installation in frame or chassis:

See details in separate manual for selected frame type.

See also Configuration section.

Video connections:

Video signal connections are made to BNC coaxial connectors. No termination of inputs is provided on the module.

When switched to the output the input load impedance is that of the load connected to the output. If AMS-4170T is

being used for a 2x1 switch application, second output should be terminated with a BNC terminator of correct

termination resistance to match source impedance, usually 75 Ohm.

Audio connections:

Audio signal connections are made to plug in balanced screw terminating connectors. No termination of inputs is

provided on the module. When switched to the output the input load impedance is that of the load connected to the

output.

Control connections:

Control connections are via SK 5 plug in screw terminating connector located on the rear assembly.

Connecting the appropriate control input to ground will cause the relays to operate and the output state to cross over

as follows: Control Input Output

High (or O/C*) A ↔ A

B ↔ B

Low (Gnd) A ↔ B

B ↔ A

Control input connector SK 5 pin configuration is as follows:

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.

Maintenance & storage

Maintenance:

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.
