3. A live data Sim 

4. Additional mounting bracketry (not included as standard) see our website for examples


Test the Outdoor Unit

1 – Fit your SIM into the SimRush ODU. if using only one sim then use “SIM A” only. Ensure the SIM is sprung into place properly.

2 – Insert patch cable into the ODU as shown below. Use “Eth1” not “Eth2”.  If using your own cable do not use booted RJ45.

3 – Insert other end of the patch cable into Port 5 of the SimRush Controller as shown below.

4 – Power on the Controller using the power supply provided.

5 – Verify the ODU is receiving a signal. You will see green lights inside and on the rear of the ODU.

6 – On the indoor controller, Ethernet Port 5 should now indicate a red colour to show power is being delivered.

6 – Disconnect the patch cable from the Controller and the ODU and set the items aside for later.

If you cannot get power to the ODU, check the cabling is correctly & fully inserted into the ports on both SimRush devices and the main power supply to the controller is turned on. If there is still no power to either device then please contact your supplier.

Determine the external location for the SimRush ODU

1 – Plan the optimum location for your Outdoor Unit to be placed. The location you choose for your outdoor device can have a huge impact on its performance. To ensure the best speeds possible ensure:

  • The ODU is facing the closest transmitter of your SIM’s carrier.
  • Your chosen location has as much height as possible.
  • Clear line of sight between ODU and transmitter where available.  Avoid Buildings, walls, rooflines, metal, double glazing where possible. Consider signal height, reflections & obstructions.

2 – If you have a smart phone you can download the OpenSignal App to identify the direction of the nearest mast with the carrier you are using (You must be using a phone with the same data carrier as the Sim in the ODU).

Android – Download the app from Google Play Store “OpenSignal”

iOS – Download the app from Apple Store “OpenSignal”

Determine the Internal location for the SimRush Controller and plan the cable run between the external and internal devices

  • The SimRush Controller needs to be placed near to a power outlet.
  • We suggest you locate the SimRush Controller in a living room, office or other space where you will want use the WiFi mostly. If you want to extend your WiFi coverage later you can purchase additional SimRush devices to do that.
  • Plan the cable route from the ODU to the Controller, the maximum route cannot exceed 40 meters in cable length. For cable runs of 40-90 metres please see our support pages for further information.
  • Remember: the cat5e cable will need to pass from the outside of the premises to the inside so you will need to locate or create a suitable entry point into the building for the cat5e cable to pass through. (If you need to drill a hole for the cable to pass through ensure it is 10mm diameter minimum).

Install the ODU fixing point

⚠ Warning! this installation requires working at height. Ensure the install is only completed by a person who is competent at working at height.

The supplied ODU bracket can be used to mount the ODU to the fixing location which is a pole. If a flat surface mount is required, a mounting adapter should be ordered separately.

Mount the ODU

Option 1:  Mounting to a Pole

Mount the ODU bracket to the pole.  Ensure the mounting bracket is fixed to the pole using the jubilee clip provided with the clip on the upper side as indicated below.  Do not fully tighten the jubilee clip at this stage, allow a little movement so that the bracket can be moved for directional alignment.  It can be fully tightened once the ODU has been positioned to receive the optimum signal achievable.

Option 2: Using A Mounting Adapter to install on a flat surface

  1. Mark out placement of holes for screws on suitable flat surface and drill holes in marked location.
  2. Fix mounting bracket to flat surface using screws provided.

Fix External Cable Run

  1. Ensure there is a small coil of excess cable remaining near to the ODU to create a ‘drip loop’ as shown.
  2. Secure the cable from the end of the drip loop section along / down the building to the external entry point. we recommend fixing the cable every 45cm.
  3. Insert the un-terminated end of the cat5e cable through the external entry point and go inside the premises to pull it through.
  4. Before securing the last external cable fixing, make sure you have a ‘drip loop’ to prevent water ingress.

Fix Internal Cable Run

  1. Attach the pattress box to the wall over the hole where the cat5e cable enters the premises, or if the cabling requirement extends further into the property use standard cable clips to run the cable around the walls to the desired location and enter the Pattress box from the side or base, removing cable entry blanks on the Pattress box as desired.
  2. Cut the cable to the desired length, be sure to leave enough cable so that you can strip back the outer sheath without damaging the internal cores.
  3. Use the tool-less Keystone Jack to terminate the cable.
  4. Attach the shutter any blanking plates as required to faceplate.
  5. Attach the keystone jack to the shutter
  6. Screw faceplate to pattress box attached to the wall to create your new socket.
  7. Connect your ethernet patch lead into the new socket.

Connecting the SimRush ODU to the SimRush Controller

  1. Connect the other end of the ethernet patch lead into port 5 of the Controller and check the Ethernet port 5 light is orange. (see fig *) DO NOT USE ANY OTHER PORT OR THE HARDWARE WILL NOT WORK!
  2. Connect any device to the SimRush WiFi for testing. The default WiFi key is your Controller Serial number which can be found on the base of the SimRush Controller. The upper-case hexadecimal serial number does not include the “/ ###” digits at the end. Only use the long serial number code.
  3. If you do not wish to use WiFi you can connect your device with a cable using Ethernet ports 2, 3 or 4
  4. Wait two minutes.
  5. Verify the connection is live– browse to freeclix.speedtest.net and do a speedtest.

Align the ODU

First Alignment

  • Using the green lights (pictured above) on the back of the ODU will help you to get an indication of the best direction to point the ODU. (This is very useful if you have not been able to use the Open Signal App)
  • Rotate 5 degrees then wait 5 seconds each time for the lights to update. More lights = greater signal.
  • Mount the ODU to the bracket ensuring the clip is holding the unit firmly in place. Push the ODU down firmly until the clip retains it in place as shown below.

Fine Alignment

The directional antenna in the SimRush ODU is highly sensitive and minor adjustments in its position can make a huge impact on its performance. To assist in selecting the fine optimal alignment of the direction of the SimRush ODU you can use our alignment help webpage.

(You can only access this page when both SimRush devices are powered on. If you wish to use the alignment page then do not secure your ODU in its final position until you have completed these steps)

  1. Ensure you have completed “Connect to the SimRush WiFi” section above
  2. Open your preferred web browser
  3. Browse to
  4. Once the page has loaded the Bar Graph showing the signal levels are broken down into 3 bars
  5. Move the ODU in 5 degree increments to achieve the best result. SINR is the key indicator to watch, get this as high as you can. The higher the SINR level the better the service. A minimum of ‘+5’ is required.
  6. Make the final alignment of the ODU using the table and graph shown below and then make final adjustments to jubilee clip other fittings used.

Complete the Install

Well done! Your SimRush is nearly installed!

Externally: Fill external opening of drill hole with Silicone and add an external weather cover.  Tidy any excess cable into a drip loop as shown and secure to the wall with cable clips.

Additional Steps

Do you have other equipment to connect to the internet?

Using ports 2,3, or 4 ONLY to connect your other devices Do not connect any other hardware to port 5, or the SimRush will not work.

Do you want to use another internet (WAN) connection as a Load-balancing or Failover?

Connect to Port 1 ONLY. It will not work with any other port.

If you wish to connect an existing internet router to the new service, the router must be giving out DHCP from address of and connected to Ethernet port 1 (AUX1) on the SimRush device only.

By default, the SimRush will utilise both the SimRush LTE connection and the auxiliary broadband connection simultaneously in load-balanced mode.  If you require a failover configuration instead, please contact SimRush support to make the adjust for you stating which WAN connection are desired to be primary and secondary.
