2.3. Hardware Installation Guide

2.3.1. Introduction

This document outlines the process of planning and installing the physical Cascade-500 IoT Gateway hardware. It lays out common planning questions to be considered, recommendations from Rigado, and the physical mounting and installation process. Please read through the entire document prior to beginning installation of hardware.

2.3.2. Planning

Planning is key to the success of any hardware installation. There are many things to consider when installing a wireless system into a space. Key elements for consideration are listed in the sections below.


In a typical commercial space you can generally expect a coverage area of about 4,000 sq. ft. per gateway. However, the area of coverage for each gateway is dependent on the layout and construction of the facility where it is installed. A gateway in an open floor plan will have a larger coverage area than a closed floor plan with many walls. Building construction materials also affect coverage: drywall and glass permit more coverage than brick and concrete.


Coverage planning should give consideration to brick or concrete walls, as you should not expect to get much penetration through those materials. If you require coverage on both sides of a brick or concrete wall, plan for a gateway on each side.

If a higher level of coverage planning precision is required, Rigado suggests using a Wi-Fi site planning tool to simulate coverage. There are multiple planning tools available online, both free and professional. For use in this application the tool should allow for changing the characteristics of the Access Points to match those of the Cascade-500 IoT Gateway (these specs are available from Rigado upon request).


Correct placement of gateways is important for getting the desired coverage. Generally, mounting gateways up high and out of reach is recommended, as this improves line of sight while making the units more difficult to tamper with. Special consideration should be given to any metal near the mounting area, such as in support beams or HVAC ducts.


Rigado recommends against mounting the gateway directly to any large metal surface.

Gateways do not need to be visible for operation. It is common to mount gateways above drop ceilings, to either the wall or a drop from the ceiling. When mounting above drop ceilings or in open office style spaces, it is recommended to mount the gateway below the level of any ceiling HVAC ducts to avoid dead spots.

Wall Placement Guidelines

  • Mount with the face towards coverage area, with the tab horizontal (The tab is the stripe on the face of the gateway, with a button and LED at one end).
  • Mount high and out of reach/active work area to avoid damage
  • Mount above tallest obstructions
  • Mount away from corners to maximize coverage
  • Mount away from shelves, cabinets, HVAC ducts, and other obstacles
  • Goal is to maximize line of sight to coverage area

Ceiling Placement Guidelines

  • Mount on lowest available mounting point facing downwards
  • Mount below I-beams or support beams
  • Mount away from HVAC ducts
  • Maintain clear line of sight or minimize obstacles to desired coverage areas


The types of connections required should be taken into consideration when planning a new installation. In order to function, the gateway needs both a power and Internet connection. For power, the options are PoE (Power-over-Ethernet) or AC wall power (adapters available upon request). For Internet connection, the two options are Wi-Fi or Ethernet. If you are using a Cascade 500-W, then cellular connectivity is available as well.

Rigado suggests using PoE-enabled Ethernet for gateway connection. PoE connections allow for both data and power to be provided to the gateway, requiring only one cable for installation. Special consideration needs to be given when choosing to use Wi-Fi, as the gateway is always connected and does not have a physical user interface. Most corporate IT policies require updating passwords after a set number of days, which would break a gateway’s Wi-Fi connection and require manual configuration on each gateway in order to update the password. Cellular connectivity is a good option to work around these considerations, however a monthly data plan must be established.

Pre-Site Planning Checklist

Summary of useful considerations when planning a gateway installation:

  • Site location
  • Area of where the sensors will be installed
  • Available power outlets and height/distance from coverage area
  • Is there a tall ceiling or obstructions to plan for?
  • Is the area protected from the elements and/or temperature controlled?
  • Check Wi-Fi or cellular signal strength in the proposed coverage area
  • Decide gateway count and mounting location

2.3.3. Gateway Hardware

Power Supply

Power can be delivered through the barrel jack or through PoE. Power through the barrel jack (5.5mm x 2.1mm) should be 4.5 to 5.5VDC (3A max for LTE, 2A otherwise). The optional DC power adapter has a 5’ cable length.

PoE can be delivered via the Ethernet connector (RJ -45) at 36-57V (IEEE 802.3af). PoE can be powered from a wall outlet with PoE injector or PoE switch. The remaining cable can be run as Cat5e ethernet cable.

Operating temperature is -20 to +70°C.

Interfaces (Cascade 500 and 500-W)

Interface features are described throughout this section, including power and data connectivity, and button and LED location and behavior.


1. Ethernet with Power-over-Ethernet Support

The gateway is equipped with a single 10/100 Base-T Ethernet connector. For configurations supporting PoE (802.3af), the gateway will operate when powered by either a PoE switch (endspan) or injector (mid-span).

2. Reset Button

The reset button provides both soft and hard reboot capabilities, depending on the length of the press. The timing is described in the following table:

Table 2.5 Reset Button Behavior
Reset Action Time Behavior
Quick Press < 2 seconds Soft Reboot
Short Press 2-4 seconds Network Reset
Long Press 10-15 seconds Hard Reboot
Very Long Press > 30 seconds Factory Reset

A Soft Reboot will restart the operating system on the gateway without interrupting power.

Network Reset clears all connections configured by network configuration and requires the button to be pressed for 2 to 4 seconds. To aid timing for Network Reset, the LED quickly flashes yellow to indicate the window when the LED should be released. When the button is released during that window, the LED will quickly flash green to confirm the Network Reset operation has been triggered. If released after 4 seconds, the LED will return to the behavior it displayed before quickly flashing yellow. If the button is released between 4 and 8 seconds, no actions (Reboot or Reset) are performed.

A Hard Reboot will reset the processor, and restart the operating system.

Factory Reset should not be performed unless instructed to by Rigado Support staff. Factory Reset will wipe all data from the gateway and re-install the operating system. If the gateway loses power during the re-install process, the installation might be corrupted and the gateway rendered inoperable. If performing a Factory Reset, do not remove power while the LED is solid yellow.


Network settings are persisted through a Factory Reset. This enables a device that was configured for Wi-Fi to regain network access after a Factory Reset is performed. To clear network settings, be sure to run a Network Reset.

3. USB

A USB 2.0 Type-A connector on the gateway board provides access to a High Speed (up to 480Mbps) USB host.

For security, the USB port will not automatically recognize standard USB devices. Rigado must implement authorization on the gateway to allow USB devices to be recognized and applications on the gateway are not given access to the USB interface.

4. Barrel Jack

The gateway provides a 5.5mm x 2.1mm barrel jack for 5V DC input. Any AC/DC wall adapter used to power the gateway needs to be rated up to 2A.


5. Front Button

A front facing button is located on the face of the gateway. This button is not enabled on the default gateway configuration.

6. Multi-color LED

A multi-color (red/yellow/green) LED located near the user button provides a means of visual indication for the user. For additional information regarding LED behavior, please refer to Gateway Boot Status.

7. Cable Cover

The back of the unit has a snap-in cover for improved cable management. This allows for hidden cable routing when the unit is installed on a wall or ceiling. The cable cover is removable.

Additional Interfaces for the Cascade 500-W

The Cascade 500-W IoT Gateway with cellular has more physical features than its non-cellular counterpart.

Mounting Equipment

A mounting kit is an available accessory for each Cascade-500 IoT Gateway. The mounting kit includes:

  • 1 x Cascade mounting bracket
  • 1 x Cascade ceiling backer plate
  • 4 x M3 x 50 mm Length, Pan Head, Phillips #1, Machine Screw
  • 4 x Screw, Pan Head Phillips Sheet Metal #6/18x1.25”
  • 4 x Drywall Anchor, #6-#8 Screw, 1-1/4” Length

To use the Wall/Ceiling Mount kit provided, the following tools are required (not included):

  • Phillips screwdriver
  • Drill and drill bit - 3/16” for wall, or 1/8” (3-4 mm) for ceiling mounting
  • Drywall saw or keyhole saw for 1” cable pass-through hole

Mounting Instructions

Rigado recommends mounting the gateway with the tab pointing to the side (mounting bracket installed as shown below). This correctly orients the antennas and maximizes gateway coverage. For the 500-W, the external antennae should be mounted facing up and angled away from any metal for optimal cellular reception.

Use the mounting bracket as a template to mark the hole locations on the wall or ceiling. If mounting to the wall, use a 3/16” (5 mm) drill bit. If mounting to a ceiling tile, use a 1/8” (3-4 mm) drill bit.If a hole is needed for any cables, also mark this in the appropriate cable opening space in the mounting bracket.


Attach the mounting bracket to the surface using the appropriate method:


Push the provided drywall anchors into the drilled holes, then place the mounting bracket snugly against the wall. Using a screwdriver, screw the wall mount screws into the drywall anchors.


Place one ceiling mount screw through one of the mounting brackets screw holes, and push through the corresponding drilled ceiling hole. Use this screw to guide placement of the ceiling backer plate to the opposite side, then use the screw to screw in this and the remaining ceiling mount screws.

Once the mounting bracket is installed, line up the four hooks of the mounting bracket with the corresponding holes on the back of the gateway and press the two together. To lock in place, slide the gateway over towards the cabling hole until it clicks into place.

Mounting Alternatives

The ceiling mount kit can be used to mount the gateway around a bar or beam. Large metal surfaces can interrupt or degrade signal strength for BLE, Wi-Fi, or cellular. Installing a gateway on a metal beam should be done only when the gateway has line-of-sight to the sensors and devices it connects to.
