2.3 - Wireless Link Quality LED's

The green Wireless Link Quality LED's are used to indicate the quality of the wireless connection between nodes.

HIGH indicates 100% link quality, while LOW indicates approximately 80% link quality (i.e. 80% of the receiving packet intact.) For the most stable and reliable wireless connection, the link quality should be at HIGH, or as close to it as possible.

In a network with one or more Repeaters, each node indicates the link quality between itself, and the nearest node that it can reach in the direction of the Output node.

2.4 - Restart Button

The Restart button can be used to reboot the node in the event of a malfunction. (This action is the same as turning the power on and o again - all user settings will be retained.)

For example, in the network below:

› The Input node indicates quality of link C › Repeater 2 indicates the quality of link B › Repeater 1 indicates the quality of link A › The Output node indicates the quality of

link A

To prevent accidental use, the Restart button is inset and can only be pressed with a ne-tipped, blunt instrument, such as a pen or small screwdriver.

QUICK START

1 - Congure your system using ToolBox

The Twin Link is dispatched from the factory with the default input type of 4–20mA, and all Setpoints set to Transparent Mode (see 10.1). If you

wish to keep the defaults, you can skip to Step 2 now. To change your input type, output scaling or setpoint conguration:

A Install Dene ToolBox (see Section 5).

B Connect the Input node (P2P-I) to your computer using the USB

Bridge Key (see 6.2). Then launch ToolBox and click the 'Connect' button (see 6.3).

C Congure your system as required, referring to 6.3–6.5 in this manual,

and also the Help Panel in the soware. You may like to wire your Input and Output nodes now, using the diagrams in the Help Panel as a guide.

D When you are nished conguring your system, click 'Disconnect' in

ToolBox, and then disconnect the Input node from your PC.

Note that it is usually not necessary to connect the Output node or the Repeater to your PC, unless the Wireless Transmit Power or Mesh ID needs to be adjusted (see 6.5).

2 - Install Output node

If possible, your Output node (P2P-O) should be powered up rst when setting up your Point-to-Point system.

A Install the Output node (P2P-O) in an enclosure at the output location

(see 4.3).

B Supply power to the node (see 8.2).

C Wait until the NTWRK STATUS 1 and NTWRK STATUS 2 LED's (2.1A)

start toggling. This indicates that the network has been successfully created, and the unit is ready to connect to other nodes.

D Wire your analog outputs (see 8.3). You may also wire your digital IO's

and relays now, if desired (see Section 10).

The analog outputs will briey output 3mA when the node is powered up or restarted. They will then output a 3.6mA fault signal until a successful link with an Input node (P2P-I) is established.

3 - Install Input node

A Install the Input node (P2P-I) in an enclosure at the input location

(see 4.3).

B Supply power to the node (see 9.2).

C Referring to 9.3A–9.3G, wire the two input channels as required for

your application. You may also wire your digital IO's and relays now, if desired (see Section 10).

4 - Check connectivity

A Please wait at least 2 minutes aer powering up the Input node for

the wireless connection to be made. When a link has been successfully established, the NTWRK STATUS 1 and NTWRK STATUS 2 LED's (2.1A) on the Input node will start toggling.

If the NTWRK STATUS LED's do not change from ashing to toggling, then a connection cannot be established, and one or more Repeater nodes may be needed (see Step 5, below).

B Check the 4 green Wireless Signal LED's on the Input node (P2P-I),

to establish link quality (see 2.3). If the link quality is low, then one or more Repeater nodes may be needed (see Step 5, below).

5 - Add Repeaters

If a successful link cannot be established between the Input and Output nodes, or the link quality is low, then one or more Repeater nodes can be added.

Note that for a successful wireless connection (using the included 3DBi antenna), all nodes must be within a range of 0.9mi (1.5km) LOS. If line of sight is impeded by buildings or topography, the transmission distance must be reduced until a strong signal can be obtained.

A Install each Repeater (P2P-R) in an enclosure at a location that is in

line of sight from any nodes it will communicate with (see 4.3).

B Supply power to the node (see 11.2).

C Provided the Mesh ID of the Repeater is a match to the Input and

Output nodes, the Repeater will be automatically detected and in-

cluded into the network. (See 11.3 for more about the Mesh ID).

4.3 - Installation Instructions

Dene Instruments P2P nodes are rated IP20. Nodes should be mounted in protective enclosures, to protect them from weather conditions and dust.

For a successful wireless link to be made, each P2P node must be located at a distance of no more than 0.9mi (1.5km) LOS from other nodes that it will communicate with. If using the WG-8DBI antenna, this distance may be increased to 4km (2.5mi) LOS.

A - Plastic Enclosure (Fig 1)

Prepare the Plastic Enclosure (not supplied) as illustrated by mounting a DIN 35 rail, cable glands, and any other required components.

The antenna may be mounted directly on the P2P unit (inside the Plastic Enclosure).

B - Metal Enclosure (Fig 2)

Prepare the Metal Enclosure (not supplied) as illustrated by mounting a DIN 35 rail, cable glands, and any other required components.

This enclosure type should be earthed.

A Metal Enclosure will impede wireless signal strength if the antenna is mounted internally. In this case, the antenna must be installed on the outside of the enclosure, using the WG-AEC Antenna Extension Cable (sold separately).

C - DIN Rail Mounting (Fig 3)

To clip the unit onto the DIN rail: (1) Hook the upper part of the unit onto the rail, and then (2) Press down towards the rail until the red hook clicks into place.

Leave at least 0.8" (2cm) clear on either side of the unit, and at least 2" (5cm) clear above and below the unit, to allow room for airow and wiring.

This will release the hook, allowing the unit to be detached from the DIN rail.

4.4 - EMC Installation Guidelines

Fig 4

All products in the P2P series have been designed to cope with large EMC disturbances. This has been achieved by continual

testing and improvement of ltering and layout techniques over many years.

P2P nodes meet CE noise requirements, and even surpass them in many tests. (For full details and test results, see Appendix A.) However in some applications with less than optimum installations and large power switching, the EMC performance of a P2P node can be further improved, by:

A Installing the node in an earthed Metal

Enclosure (see 4.3B). This is particularly

useful if the control box is mounted close to large power switching devices like contactors. Every switching cycle there is a possibility of generating a large amount of near eld radiated noise. The Metal Enclosure, acting as a faraday cage, will shunt this radiation to ground and away from the P2P node.

Further improvements can be made with this type of noise by increasing the physical distance from the power devices. For example, increasing the control box distance from 6" to 12" from the noise source will reduce the noise seen by the control box by a factor of 4. Probably the cheapest and best results in this

situation could be obtained by adding RC snubbers to the contactors or power switches.

B Using shielded cable on sensitive input

and control signal lines. Good results can be obtained by grounding the shields to the metal enclosure close to the entry point. All cables act as aerials and pick up unwanted R.F. radiated signals and noise; the earthed shield acts as a faraday cage around the cables, shunting the unwanted energy to ground.

Shields can also help with capacitively coupled noise typically found in circumstances when signal cable is laid on top of noisy switching power cables. Of course in this case you are better o to keep separate signal and power lines.

C Laying cable on earthed cable trays can

also help reduce noise seen by the P2P node. This is particularly useful if there are long cable runs, or the unit is close to radiating sources such as two way radios.

D The relay outputs of the P2P-I and

P2P-O nodes have built in MOV's to help reduce EMI when switching inductive loads. EMI can further be reduced at the load by adding snubbers for AC signals or a yback diode for DC coils.

ToolBox oers a smart, no-fuss setup experience for your Twin Link Point-to-Point system, and has been designed to simplify and speed up conguration.

You must install ToolBox before connecting the Twin Link to your computer. If you have already connected your Input node using the Bridge Key, please disconnect before continuing.

6.5 - Mesh ID, Wireless Transmit Power

Mesh ID and Wireless Transmit Power are the only two settings that must be congured individually for each P2P node. Because of this, they are also the only settings that require you to connect to your Output node (P2P-O) or your Repeater (P2P-R) using the ToolBox soware. (All other settings are congured by connecting the Input node [P2P-I].)

Mesh ID

Each P2P node has a Mesh ID code, which is printed on the product label. This 16-digit code is used to link the node to other nodes in the network.

The Mesh ID of the Output node is considered the 'parent' ID of the network, and cannot be edited.

The Mesh ID of the Input node is matched to the Output node by the manufacturer, prior to dispatch. In the event of a fault requiring replacement of one of the Twin Link nodes, the Mesh ID of the Input node may be edited. This can be done on the 'Overview' page in Dene ToolBox.

The Mesh ID of any Repeater node(s) used must also match that of your Twin Link. Any

Repeater nodes that you order with your Twin Link will be Mesh ID matched by your

distributor, so there is usually no need to congure this setting.

If additional Repeater nodes are added at a later stage, then you may need to set them to match the Mesh ID of the Twin Link pair (see 11.3 for instructions).

A Repeater that has a clear line of sight to other in-range nodes, with a matched Mesh ID, will be automatically incorporated into the network.

Wireless Transmit Power

The Wireless Transmit Power setting oers a selectable list of regions. Selecting the region in which the P2P network will be used, will set the transmission power of the node to comply with local regulations.

Region Transmission Power Complies With

New Zealand & Australia +20dBm (100mW) AS/NZS 4268:2012

USA +20dBm (100mW) FCC Part 15.247

South Africa +10dBm (10mW) ETSI EN 300 440-2

Europe +10dBm (10mW) ETSI EN 300 440-2

IMPORTANT

Regional regulations may have changed since manufacture of this product or publication of this manual. It is the responsibility of the assembler of the system to ensure that the system fully complies with all local codes and requirements.

Note that each node in the system must be individually set for the correct region, by connecting the node to Dene ToolBox, selecting the region, and then clicking 'Apply'.

Label Side (Right)

DIN

Electrical connections are made via plug in terminal blocks on the top and bottom of P2P nodes. All conductors must conform to the unit's voltage and current ratings, and be suitably rated for the expected temperature range to be incurred.

When wiring your P2P nodes, check all connections against the terminal numbers printed on the label, and the appropriate wiring diagrams in this manual (Sections 8–11) or the Dene ToolBox soware.

Strip the wire, leaving around 0.25" (6mm) of bare lead exposed. If you are using stranded wire, this should be tinned with solder. Insert the lead into the correct plug in the correct position, and tighten until the wire is secure. Verify tightness by pulling on the wire.

Follow all local codes and regulations when wiring and installing your P2P node.

DIGITAL I/O'S & RELAYS

10.1 - Overview

Each digital IO and relay output is mapped to a corresponding channel on the opposite point, depending on the Setpoint Mode selected during initial setup using Dene ToolBox. There are three soware modes that may be selected:

Transparent Mode

In Transparent Mode, each relay or digital output on the Output node is controlled by its corresponding digital input on the Input node, and vice versa.

This is ideal for the transfer of slow pulses through the air to PLC's and SCADA systems, or for manual remote control of appliances and machines.

It is recommended that you congure your setpoints in Dene ToolBox (see Section 6) before continuing with wiring your digital IO's and relays. Once soware setup is complete and you have decided exactly how each setpoint will be used, to the terminal numbers printed on the product label.

Alarm or Control Mode

Alarm Mode is ideal for tripping alarms or

for alerting an operator to key system conditions. Control Mode is designed to control other equipment (such as turning pumps and heating units on and o).

In both Alarm & Control modes, the input channels control the relays and digital outputs on both the Input and the Output nodes.

REPEATER NODE

11.1 - Overview

The Point-to-Point Repeater is the perfect addition to a Twin Link system where the Input and Output nodes are out of range, or a line of sight connection is interrupted by buildings or hilly terrain. It works by retransmitting incoming signals from other nodes in the network, enabling you to boost your range and navigate around obstacles.

A Repeater will extend the range of your Twin Link by up to 0.9mi (1.5km) LOS using the supplied antenna. Add up to 15 repeaters in a single Point-to-Point system, and that’s a wireless transmission distance of up to 14.9mi (24km).

11.2 - Supply Power

Pins 20–21

Supply 9–36V DC to the Repeater node (P2P-R) as shown (right). The power terminal is located on the underside of the P2P-R, and is the only wiring terminal on the unit.

Wait up to two minutes, and then check the NTWRK STATUS LED's on the front of the Repeater unit. If the LED's start toggling, then the Repeater has successfully integrated with your Twin Link, and no further setup is required.

If the NTWRK STATUS LED's do not start toggling aer waiting a few minutes, and you are sure that all P2P units are in range and line of sight, please see 11.3.

11.3 - Check the Mesh ID

Connections between P2P nodes are established using a Mesh ID code (see 6.5). If you ordered your Repeater with a Twin Link, then all of the Mesh ID's should have been matched by your distributor, and it is not necessary to continue with 11.3.

If the Mesh ID's are not yet matched, or you are having diculty pairing a Repeater and would like to check the Mesh ID:

A Supply power to your Repeater (P2P-R),

and then connect the node to your computer using the Bridge Key (see 6.2).

B Launch Dene ToolBox and click

'Connect'.

C ToolBox will display the 'Overview' pan-

el. Check the Mesh ID number against the number printed on your Twin Link. If required, edit the Mesh ID number and then click 'Apply'.

D Disconnect from ToolBox.

E Once the Mesh ID’s are matched, and

all units in the system are in range and line of sight, the new node will be automatically included in the network.

MAINTENANCE

12.1 - Calibration

Your P2P units have been fully calibrated at the factory, and can be recalibrated in soware using Dene ToolBox (see 6.3 to connect). Scaling to convert the input signal to a desired display value is also done using ToolBox.

If your P2P unit appears to be behaving incorrectly or inaccurately, refer to troubleshooting before attempting to calibrate it. When recalibration is required (generally every 2 years), it should only be performed by qualied technicians using appropriate equipment.

Calibration does not change any user programmed parameters. However, it may aect the accuracy of the input signal values previously stored.

12.2 - Troubleshooting

Issue Resolution

Input & Output nodes are not pairing

Repeater node(s) are not pairing

Output node outputs 3mA continuously

Output node outputs

3.6mA continuously

Check that both nodes are powered up, in range, and line of sight.

Check that the Mesh ID's printed on the labels are identical. If they are dierent, set the Mesh ID of the Input node to match the Output node, referring to 6.5.

Check that all nodes in the network are powered up, in range, and line of sight.

If this is not the issue, then the Mesh ID of the Repeater needs to be set. Please see 11.3.

This is a fault signal, which indicates that the units are not paired. Check that all units are powered up, in range, and line of sight. You may need to add a Repeater node to achieve a wireless link (see 11.1).

This is a fault signal, which indicates that the network link has been broken. Check the power to the Input node, and check that the RF surrounding has not changed. If the quality of the wireless link is low (see 2.3), you may need to add a Repeater, use to a higher power antenna, or reposition your node(s).

For further assistance, please contact technical support using the contact details listed at the end of this document.
