Installation

This guide relates to the installation and setup of the Green Bidirectional Point to Point (PtP) modules in the different operational configurations. This guide applies to Green Bidirectional Point to Point (PtP) modules that support 433, 868, and 915MHz license-free ISM wireless bands used in various regions around the globe.

NOTE: Before commencing with the installation, please read the following.

• Do not locate this equipment near high voltage power lines. Take special precautions to avoid any contact with high voltage power lines when installing this equipment.
• Avoid locating this equipment close to a roof structure.
• Avoid locating this equipment near dense foliage and vegetation.

Installing the PtP Modules Antenna and the Antenna Cable

NOTE: Antennae structures and designs may differ based on the frequency band being used)

Industry best practices include

• Mount the PtP Module(s) and the system antenna on a pole in free air space.
• The pole should be of a rigid construction with an outside diameter of between 30 and 50mm.
• The equipment should be located on the pole as high as is practically possible above ground level.
• Different antennae can be used depending on the topography of the terrain where the system is located. For example, it would be possible to make use of a stubby antenna in a small-scale system that only requires line of sight (LOS) coverage of a few hundred meters between Modules.

This document will demonstrate the installation of an Omni directional dipole antenna; however, the installation processes for a Yagi-type directional antenna is practically the same.

1. Remove the antenna and the antenna’s “U” bolt(s) or mounting clamp from the packaging.
2. Install the antenna at the top of the mounting pole with the cable and or cable connection facing downwards as shown in the images below.

Installing and Wiring the PtP Module

1. Remove the module from its packaging then remove the module’s lid. The lids fasteners are spring-loaded and need to be pushed and turned 90° anticlockwise simultaneously to release them.
2. Install the PtP modules stainless steel mounting plate using four M4 x 8mm pan head galvanized or stainless steel machine screws and four M4 nuts. Fit the mounting plate to the module using the four mounting holes provided in the corners of the box. See the images below.

• The PtP module requires a 12VDC (Min. 0.10A) power source where the POSITIVE wire is connected to the +12V terminal and the NEGATIVE wire is connected to the GND terminal as per the image below.
• The PtP module is equipped with two digital inputs. Inputs are triggered when the GND terminal is bridged with the InPut terminal (IP1 or IP2). Any switching device can be connected to the input such as a reed relay (from a water meter), a float switch, a simple toggle switch, or a relay’s contacts. They are connected as per the image below.

Wiring the Outputs

The PtP module is equipped with two relay outputs. The outputs are normally open circuits and will close when a signal is received from the Master module(s). Outputs can be used to activate pumps, valves, provide water meter back indication and numerous other processes.

Setting the PtP Modules System ID

• All settings on the PtP Modules are carried out by adjusting the dip (Dipswitch bank #1 and #2) switch setting within the module. Note that power must be off while making any dip switch setting changes.
  • SW1.1 = 128
  • SW1.2 = 64
  • SW1.3 = 32
  • SW1.4 = 16
  • SW1.5 = 8
  • SW1.6 = 4
  • SW1.7 = 2
  • SW1.8 = 1

E.g. In order to set a System ID of 119, switches 1.2 (64), 1.3 (32), 1.4 (16), 1.6 (4), 1.7 (2) and 1.8 (1) must be on, and the others off. This setting is thus 64 + 32 + 16 + 4 + 2 + 1 = 119 Take note that the last digit in the system ID relates to the frequency channel being used. There are 10 channels available (0 to 9) and in areas where a number of different systems are installed, it would be prudent to select a channel that is not in use to prevent unwanted interference by other systems. In the ID example above, system ID 119 will be using channel 9. Systems with duplicated System IDs should not be located within a 50km radius of each other. It is advisable to log the GPS coordinates of each system installed for future record keeping.

Setting the PtP Modules Operating Mode for the Outputs

Each output relay within a PtP Module can be set as “Active” or “Inactive”. If an output relay is set in the “Active” mode, the PtP module will listen for an incoming signal from a Master (Transmitter) PtP module and react accordingly. If an output relay is set in the “Inactive” mode, the PtP module will ignore any signal relating to this specific output relay.

• Dip Switch SW2 switch 8 is used to set the mode for Output Relay #1 within a PtP Module.

SW2.8

| On| Active
---|---|---
Off| Inactive

• Dip Switch SW2 switch 7 is used to set the mode for Output Relay #2 within a PtP Module.

SW2.7

| On| Active
---|---|---
Off| Inactive

Setting the PtP Modules Operating Mode for the Inputs

Each digital input within a PtP Module can be set in “Pulse” or “Switch“ mode. If a digital input is set in “Pulse” mode, the PtP module will act as a Master and transmit a pulse-type signal. A PtP module that has its relay output (with the same number as the input) set as “Active”, will receive the incoming signal and switch the relay output as a pulse. If a digital input is set in “Switch” mode, the PtP module will act as a Master and transmit a switch-type signal. A PtP module that has its relay output (with the same number as the input) set as “Active”, will receive the incoming signal and switch the relay output as a switch.

• Digital Input #1 on a Master module will only operate with Output Relay #1 on a Slave module if Output Relay #1 is “Active”. If Output Relay #1 on the Slave module is set as “Inactive”, it will ignore the incoming signal.
• Digital Input #2 on a Master module will only operate with Output Relay #2 on a Slave module if Output Relay #2 is “Active”. If Output Relay #2 on the Slave module is set as “Inactive”, it will ignore the incoming signal.

This method of setting makes allowance for a single Master PtP Module to transmit the status of both Digital Inputs to two separate Slave PtP Modules that have their respective Output Relays set as “Active”

• In the “Switch” function the status of the digital inputs on the Master (Tx) module(s) will be replicated on the outputs of the Slave (Rx) module(s). For example, if GND is bridged with IP1 on the Master module, relay 1 on the Slave module will be activated causing COM1 and NO1 on the Slave module to be connected. When the bridge between GND and IP1 is removed on the Master module, relay 1 on the Slave module will be de-activated causing COM1 and NO1 on the Slave module to be disconnected.
• In the “Pulse” function the status of the digital inputs on the Master (Tx) module(s) will be replicated on the outputs of the Slave (Rx) module(s) with a pulse of approximately 0.5 seconds in length. Typically this would be used to replicate the pulses generated by a water meter. For example, if GND is bridged with IP1 on the Master module, relay 1 on the Slave module will be activated causing COM1 and NO1 on the Slave module to be connected for around 0.5 seconds.
• Dip Switch SW2 switch 6 is used to set the mode for Digital Input #1 within a PtP Module.

SW2.6

| On| Switch
---|---|---
Off| Pulse

• Dip Switch SW2 switch 5 is used to set the mode for Digital Input #2 within a PtP Module.

SW2.5

| On| Switch
---|---|---
Off| Pulse

• Note that it‘s possible to set PtP modules in pulse and switch functions operating within the same system.

Operating the System

• Power Up
• General Notes

Power Up

• Apply 12VDC power to the PtP Module.
• At power up, both LEDs (LD1 and LD2) in the PtP Module will flash twice and go off.
• Simulate the activation of Input #1 on the PtP#1 Module by bridging the GND terminal with the IP1 terminal. LD1 LED will illuminate for a few seconds while the PtP#1 Module transmits. If the signal has been successfully received by one or more PtP Module(s) LD2 LED will illuminate for a second confirming that a signal has been received by a PtP Module. This is an acknowledgment (ACK) that the signal was received by the receiving PtP Module. If no acknowledgment is received, PtP#1 Module will continue trying to by retransmitting the signal until an acknowledgment is received.
• During this simulation when a PtP Module receives the signal from the PtP#1 Module the LD2 LED illuminates for a second or so and then acknowledges that it has received the signal by sending a confirmation transmission at which time the LD1 LED will illuminate for a few seconds.
• When a Switch or Pulse signal is received by a PtP Module an audible click from one of the relays can be heard. You can also use a multimeter to check which relay is activated. To check relay #1 (output #1), set the multimeter to continuity mode (an audible sound should be heard if the red and black probe are bridged together) and place the black probe on the COM1 terminal and the red probe on the NO1 terminal. When the relay is activated an audible sound should be heard from the multi-meter. This can be repeated for relay #2 (output #2) using terminals COM2 and NO2.
• The system is now ready for normal operation.

General Notes

• Do not drop any of the modules as this could lead to permanent damage to the module enclosures or sensitive electronic components.
• Keep the components in the original packaging until they are on-site and ready to be installed. This provides optimum protection to the equipment during the transport process.
• Avoid exposing the equipment to high vibration and or shock as this can lead to permanent damage to the equipment.
• Do not attempt to modify the equipment or the electronics as this will deem the warranty void and may lead to permanent damage of the equipment.
