Frequently Asked Questions - Qflex Isolator Klark Teknik

How to install the Qflex Isolator?

Mount the isolator on a panel using 4 mm screws in the provided holes (pitch 40 x 92.5 mm). Connect the IN, OUT, and LINK ports via RJ45 or Phoenix terminal blocks. Power is supplied via the LINK port from a VNET product or an external 12 V DC power supply.

What power supply is required?

The isolator requires a 12 V DC power supply with at least 100 mA per device. If you use multiple isolators, an external power supply is required. Power can be provided by the LINK port of a VNET product or by a dedicated power supply.

Can multiple isolators be used?

Yes, you can chain multiple isolators to segment a large network. Each isolator protects its segment while respecting the limit of 32 VNET products per network and 1 km of cable per backbone. An external power supply is required if you exceed one isolator.

How to wire the connections?

Use RJ45 cables or Phoenix terminal blocks (screw type) for IN, OUT, and LINK connections. The connectors are wired in parallel: you can use either. For backbone wiring, prefer Phoenix terminal blocks for increased reliability.

What is the function of the isolator?

The Qflex Isolator provides galvanic isolation between segments of a VNET network. It eliminates ground loops, electrical interference, and protects against wiring faults. It also allows creating star topologies and testing wiring before installing other equipment.

What to do in case of malfunction?

First check the connections and power supply. If the problem persists, contact Music Tribe support via musictribe.com. Do not attempt to repair yourself: the interior contains no user-serviceable parts. Consult a qualified professional.

How to clean the device?

Disconnect the device before any cleaning. Use a dry cloth to wipe off dust. Never use liquids or abrasive products to avoid damaging electronic components.

What are the safety instructions?

Do not open the enclosure: risk of electric shock. Do not expose the device to rain, moisture, or heat sources. Use only high-quality professional cables. For any repair, contact a qualified technician.

Can I use standard RJ45 cables?

Yes, standard RJ45 patch cables can be used for LINK, IN, and OUT connections. For backbone wiring, it is recommended to use Phoenix terminal blocks for better mechanical and electrical reliability.

What is the maximum network length?

The total network cable length must not exceed 1 km per backbone. If you use multiple isolators, each backbone can be up to 1 km, but the total number of VNET products across the entire network is limited to 32.

ISOLATOR has been designed to ease the problems often presented when large VNET systems are constructed. Specifically it addresses the following issues:

• The possibility that mains earth potentials exceeding +/-15V exists between different network nodes
• Large amounts of electrical noise and interference may be present on the network cables
• Wiring faults on the network cable damaging other network nodes
• It is desired to create networks that have a large "star" topology
• It is desired to use screw terminal terminated wiring to construct the network
• It is desired to be able to install and test the main "backbone" network cable without the presence of other equipment (including ISOLATORS)

As its name implies ISOLATOR limits these problems by making it possible to galvanically isolate different parts of the network from each other and from the controlling computer system. When any of the above situations can be anticipated then ISOLATORS should be incorporated in to the design of the network.

For systems which incorporate AES3 over VNET (VNET2), please contact you vendor for details of how to set the internal jumpers inside the Isolator. Please be aware that some of the application examples shown in this document are not applicable to VNET2 systems.

Mounting

ISOLATOR is housed in a strong galvanised steel case that can be mounted using 4 mm diameter hardware in the holes that are on 40 x 92.5 mm centres. If dust or moisture resistance is required then it will be necessary to mount ISOLATOR in a suitable enclosure. Note that the case of ISOLATOR is connected to the earth system on the LINK side of the isolation barrier.

Connections

ISOLATOR has three ports: IN; OUT & LINK. Each port has both RJ45 and "Phoenix" pluggable screw terminal blocks. These connectors are connected directly together so either may be used as convenient.

For example it might be most convenient to connect ISOLATOR "LINK" to the LINK output of a VNET device using a standard RJ45 patch lead while using the Phoenix connections for the hard wired network "backbone" cabling on the IN and OUT ports (which are also connected directly together).

Power

ISOLATOR is powered via its LINK port. As the LINK port on VNET products provides a source of suitable power, connecting the LINK of ISOLATOR to the LINK of the VNET device with an RJ45 patch cable will power it up.

If the connection from the VNET product is to use the LINK Phoenix connector of the ISOLATOR then the following connections need to be made:

VNET Cat5 Cable and RJ45 Connections

PIN PAIR COLOUR (T568B)				Product Link	Isolator Link
1	2		white/orange	data + LINK A
2 2 orange dat		CB
3	3		white/green	No Connection
4 1 blue				power out +	Ext PSU +
5	1		white/blue	power out -	Ext PSU -
6 3 green No C		on
7	4		white/brown	No Connection
8 4 brown No C		ion

If a screen cable is used, connect the screen to LINK S

As VNET products can only supply enough power for a single ISOLATOR, systems requiring more than one will need an external power supply. In this case no connection should be made between the VNET product and the "Ext PSU" connections of ISOLATOR, these connections should be used for the external power supply.

External supplies should produce regulated 12V DC with at least 100mA available for each ISOLATOR that is to be supplied. Klark Teknik can supply or recommend a suitable power supply.

If the VNET product is connected to the ISOLATOR via its RJ45 connector then as described above this will automatically connect the power from the product's LINK port to the ISOLATOR. This is not a concern because ISOLATOR contains circuitry to prevent any conflict with an external power supply.

Configurations

For maximum flexibility ISOLATOR can be used in a number of ways, below are some examples:

1. Basic IN to OUT daisy-chaining with additional branches as required.

    E["ISO"] --> F["IJK"]
    G["ISO"] --> H["IJK"]
    I["ISO"] --> J["IJK"]
    K["Network Backbone"] --> L["Network Backbone"]

1. Using only the Phoenix IN (or OUT) ports allows the network wiring to be installed and tested before other equipment is installed.

    W["ISO"] --> X["Network Backbone"]
    Y["ISO"] --> Z["Network Backbone"]

1. ISOLATORs may be used to segment a large network as convenient, protecting each segment from the others. Note that using them in this way does NOT allow the network to exceed the 1 km total maximum length limit.

1. Here multiple ISOLATORS are used to create multiple backbones. As long as the ISOLATORS are local to each other and the controlling system, then each backbone may be the full 1 km long.

Note that the maximum number of VNET products per network (not per backbone) remains 32.

1. Because of the limited power available from a USB interface, connecting the USB interface directly to an ISOLATOR will not work unless an external power supply is connected either to the rear of the USB interface or, as shown, to the ISOLATOR.
