2 Green RTU G5 Radio Repeater Module

This guide pertains to the installation and setup of the Green RTU G5 Radio Repeater Module used in Point to Multi Point (PtMP) control systems, including those utilizing serial communications or Persistent Point to Point (PPtP) systems. This guide applies to Green RTU G5 Radio Repeater Modules supporting 433, 868, and 915MHz license-free ISM wireless bands used globally.

2.1 Installing the Transmitters Antenna and the Antenna Cable

NOTE: Antenna structures and designs may differ based on the frequency band being used.

It is best practice to mount the Radio Repeater Module and the system Antenna on a pole in free air space. The pole should be of rigid construction with an outside diameter of between 30 and 50mm. The equipment should be located as high as practically possible above ground level. Different antennae can be used depending on the terrain topography. For example, a stubby antenna might be suitable for small-scale systems requiring only line-of-sight (LOS) coverage of a few hundred meters. This document focuses on using an omni-directional dipole antenna, which is common for point-to-multi-point or repeater applications.

• Remove the antenna and its "U" bolt/s or mounting clamp from the packaging.
• Install the antenna at the top of the mounting pole with the cable and/or cable connection facing downwards.
• Fit the washers provided with each U Bolt/Bolt and tighten the nuts accordingly, ensuring not to damage the mounting pole.
• Connect the 1M RG58 antenna cable to the Antenna. Loop the cable once (to allow for contraction and expansion) and fix the antenna cable to the post using a cable tie. Leave the other end of the cable loose for now.

2.2 Installing the Radio Repeater Module

• Remove the module from its packaging and then remove its lid. The lid fasteners are spring-loaded and require pushing and turning 90° anticlockwise simultaneously to release them.
• Install the repeater module's 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 transmitter module using the four mounting holes provided in the corners of the box.
• Install the radio repeater module at the top of the mounting pole, approximately 0.5m below the antenna, with the cable glands facing downwards. Pass the two U-bolts around the mounting pole and through the radio module's mounting bracket. Fit the washers and nuts and tighten the nuts.

• Extract the cable glands from inside the module and remove any wrapping. Install each cable gland into the holes provided in the base of the module.
• Feed the antenna cable through the lower cable gland and fasten the SMA connector to the radio board. Push the protection boot down through the cable gland and tighten the gland's compression fitting around the boot to create a watertight connection.
• Disassemble the right-hand upper cable gland by removing the compression nut, the split rubber insert, and the rubber seal. Select a suitable two-core cable (preferably no smaller than 0.75mm²) to act as a power cable. Pass one end of the cable through the gland's compression nut, the rubber seal, and the cable gland. Fit the split rubber insert around the cable and insert it into the cable gland.
• Wiring the Power Source: The Radio Repeater module requires a 12VDC (Min. 0.10A) power source. The POSITIVE wire connects to the +12V terminal, and the NEGATIVE wire connects to the GND terminal.

2.3 Setup the Radio Repeater Modules System ID

All settings on the Radio Repeater Module are configured by adjusting the dip (Dipswitch bank #1 and #2) switch settings within the module. Note that power must be off while making any dip switch setting changes.

Dip Switch SW1 is used to set the System ID. This System ID must match the System ID used by the serial transmitter module in the same control system. The System ID can be set in the range from 0 to 255 using binary. The dip switch numbers correspond to the following binary values:

• SW1.1 = 128
• SW1.2 = 64
• SW1.3 = 32
• SW1.4 = 16
• SW1.5 = 8
• SW1.6 = 4
• SW1.7 = 2
• SW1.8 = 1

For example, 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 totals 64 + 32 + 16 + 4 + 2 + 1 = 119.

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 installed system for future record keeping.

A Radio Repeater can only support up to 128 outputs. If using a Serial Transmitter with more than 128 outputs, decide which system the repeater will be allocated to. If the Serial Transmitter's ID is set as 119 and it uses more than 129 outputs, the Radio Repeater can be set as 119 to repeat outputs 1 to 128, or ID 120 to repeat outputs 129 to 256.

Dip Switch SW2 is used to set the Radio Channel.

• Switches 2.1, 2.2, 2.3, and 2.4 must all be set in the OFF position.
• Switches 2.5, 2.6, 2.7, and 2.8 are used to set the Radio Channel the system will use and must match exactly the settings of the main Serial Transmitter Module or the PPtP Module.

This module is now ready for testing and field operation.

2.4 General Notes

• Do not drop either module, as this could cause permanent damage to the module enclosures or sensitive electronic components.
• Keep components in their original packaging until they are on site and ready for installation. This provides optimal protection during transport.
• Avoid exposing the equipment to high vibration or shock, as this can lead to permanent damage.
• Do not attempt to modify the equipment or its electronics, as this will void the warranty and may cause permanent damage.

3 Warranty

Warranty and Technical Assistance

Munters products are designed and built to provide reliable and satisfactory performance but cannot be guaranteed free of faults. While reliable, they can develop unforeseeable defects. Users must account for this and arrange adequate emergency or alarm systems if failure to operate could cause damage to the articles for which the Munters plant was required. If this is not done, the user is fully responsible for any damage they might suffer.

Munters extends this limited warranty to the first purchaser, guaranteeing products to be free from defects originating in manufacture or materials for one year from the date of delivery, provided that suitable transport, storage, installation, and maintenance terms are complied with. The warranty does not apply if products have been repaired without express authorization from Munters, repaired in a way that, in Munters' judgment, impairs performance and reliability, incorrectly installed, or subjected to improper use. The user accepts total responsibility for incorrect use of the products.

The warranty on products from outside suppliers fitted to the Radio Repeater (e.g., cables, weights) is limited to the conditions stated by the supplier. All claims must be made in writing within eight days of defect discovery and within 12 months of the defective product's delivery.
