Getting Started
Opening the Box
The Senquip QUAD is shipped in a box with a security seal that ensures that the packaging has not been opened. If this seal is compromised, the box may have been opened, in which case, a non-authorised party could have had access to the device password. If the device is to be used in a critical application, please ensure that the seal is intact upon receipt and remember to change your password as soon as possible.

Mounting
The Senquip QUAD can be wall or bulkhead mounted, or can be attached to a DIN rail using the integrated mounting clips. When wall or bulkhead mounting, use M5 bolts.
Senquip QUAD mounting points circled in red
If attaching to a DIN rail, push the enclosure onto the rail, ensuring that the clips have fully engaged around the rail.
Rail mounting the Senquip QUAD
Remove the Senquip QUAD from the DIN Rail using the Allen Key as shown in the image below.
Removing from a DIN Rail
The Senquip QUAD should be mounted with the cable gland and antenna entry facing down. Mounting the device with the gland in another orientation may result in water ingress via the cable entry gland. In-field orientation checks can be performed using the built-in accelerometer and associated tilt measurements.
User access
The user access panel is accessed by removing the front cover. From the user access panel, a SIM card can be inserted, external devices can be wired, diagnostics can be performed, and the device can be reset or placed in setup mode.
User access for the Senquip QUAD
To open the cover:
Un-fasten the 4 hex-head screws that secure the cover using the 3mm Allen key provided. The screws are captive and will not fall out when loose. Do not attempt to remove the screws from the lid.
Four cover screws
When the lid is opened, an internal light detector will recognise the increase in brightness and will enable the LEDs and configuration switches.
Note
When closing the device, please ensure that the seal is correctly seated and is clean. A poorly seated or dirty seal may result in water ingress.
Anti tamper screw
In some installations, evidence needs to be provided where unauthorised access to the Senquip QUAD has occurred. All devices include a tamper feature that can be configured to raise an alert when the lid is opened. In some instances however, a physical tamper indication is required. Senquip can provide tamper evident screws for the lid of the Senquip QUAD. Once a tamper evident screw is in place, opening the device will require breaking the seal on the tamper evident screw.
Tamper evident screw
To fit a tamper evident screw, remove one of the lid screws closest to the cable gland using the 3mm Allen key provided. Replace the lid screw with the tamper evident version. The tamper screw is compatible with most available seals.
Note
The tamper evident screw should be inserted last and removed first. The tamper evident screw should be inserted and removed with a 4mm Allen key.

SIM card install
The Senquip QUAD uses a micro-SIM card with dimensions as shown in the figure below. Both 1.8V and 3.3V SIM Cards are supported.
If 4G LTE is the chosen communications method, then a SIM card should be installed now. The Senquip QUAD is available with an internal SIM card included. An internal SIM card provides for the most reliable communications in high-vibration environments.
Note
If your Senquip QUAD has an internal SIM card, you do not need to install an additional card.
SIM Card sizes
To access the SIM card holder, the lid must be opened. The SIM card holder is located at position 1 in the diagram below. The holder is a “push-push” type, meaning that the SIM card is pushed in to install and is then pushed and released to eject.
Identifying the SIM card slot
To insert a micro-SIM card into the holder, place it in the recess to the left of the SIM card slot and apply a gentle pressure to the right. The SIM card should be orientated with contacts facing up and the removed corner on the bottom right as in the diagram below.
Correct insertion of a SIM card
Because the Senquip QUAD is expected to be used in harsh environments, there is a plastic locking mechanism moulded into the plastics. Once the SIM card is inserted, the plastic lock will lift, securing the SIM card in the holder.
Insert SIM to the right
It is recommended that the device be reset, by pressing the reset button, after inserting a SIM card.
To remove the SIM card, hold the locking mechanism down; press the edge of the SIM card gently and let go. The SIM card will be ejected.
Wiring guide
The Senquip QUAD is fitted with a 14 way 3.5mm pitch terminal block that can be used to provide power and for connection to external sensors and systems. With the cable gland facing down, pin 1 is on the left hand side of the header and pin 14 on the right. All references to pin numbers in this document will assume this definition.

Warning
Please ensure that all external power is removed from the device before wiring fitment begins.
Power and ground wires must be rated to at least 1A and should have a voltage rating suitable for the application. A 1A fuse in-line with the power connection is recommended. Signal wires should be chosen based on the application and may require specific features such as individual shielding, twisted pairs or impedance matching. In extremely noisy electrical environments, it is recommended that a shielded cable be used and that the shield only be connected to ground on the power supply end. Do not ground the shield on both ends.
The material from which the chosen cable is manufactured should be suitable for the environment in which it is used. Be sure to check chemical resistance, UV stability and flex durability of the cable being used.
Wiring example with a sheathed cable
To ensure IP rating is retained, a sheathed cable with diameter suitable for use with the cable gland insert should be used. Three cable gland seals are supplied as specified in the table below. The gland with the single hole should be used when a single cable is required; the gland with two holes should be used where two cables are required etc. Cable seals are manufactured using NBR (Nitrile Butadiene Rubber) and are resistant to oils and biological oils, solvents and most industrial chemicals. Always check the suitability of the cable gland insert with all chemicals found in the operating environment.

Fitting the antenna
Every Senquip QUAD is shipped with a dual GNSS and 4G LTE antenna. The antenna is fitted with 2 FAKRA plugs that engage with the matching sockets at the base of the Senquip QUAD. FAKRA connectors were chosen for use on the Senquip QUAD because:
They offer vibration tolerant operation
The colour coding and keying make it simple to match the antennas with the correct connectors
FAKRA connectors avoid the opportunity to over tighten the RF connectors, causing damage
GNSS and 4G LTE combination antenna
To connect the GNSS or LTE antenna lead to the Senquip QUAD, press the antenna connector into the socket until you hear it click. To remove the connector, depress the small tab and pull.
Warning
When removing the antenna, do not pull on the RF cable.
Press the tab to remove the connector
The GNSS and 4G LTE antenna cables are colour coded and are keyed. Connector details are given in the table below.

Initial setup
Initial setup can be performed using the integrated web-server using any Wi-Fi enabled phone, tablet or computer. Once the device is connected to a network, configuration can be performed remotely using the in-built webserver or via the Senquip Portal.
Note
For volume opportunities, devices can be pre-configured to connect immediately to a network; please contact Senquip to discuss this option.
With the cover open, two push-button switches (setup and reset) and two LEDs (network and status) are available. The switches and LEDs are used to configure the device.
Buttons and LEDs for setup
The status and network LEDs indicate the current state of the device. These LEDs are only active if the lid is open. When the lid is closed, the LEDs will remain off to conserve energy. A summary of LED function is given in the table below.
Note
During normal operation, the LEDs will be off when the device is sleeping or hibernating and will not turn on when the lid is opened until the next measurement interval.

Note
The LEDs turn on when the lid is opened because an internal sensor detects light. If the lid is opened in dark conditions, the LEDs will not turn on.
Firmware Updates The latest firmware version and a description of changes to firmware can be found in the Senquip Device Firmware Changelist. Updating to the latest firmware can be performed from the Senquip Portal by selecting Settings and Update and then pressing the Update Firmware button. To update to a specific firmware version, enter the firmware number as shown in the figure below and press Update Firmware. During the firmware update, the orange network LED will flash fast. After a firmware update, the LEDs may freeze or remain off for a few minutes. This is normal behaviour and occurs shortly after firmware update when the ORB is encrypting the memory.
The firmware update can be seen in the command queue and has been received by the device when the status shows as success. Receipt of the firmware update by the device does not always mean that the update is correctly applied. To ensure that the update has occured, check the firmware number in the Device Info widget on the device Portal page. You may need to refresh the browser window.
Factory Reset To perform a factory reset, press and hold the Setup button. While holding the Setup button, press and release the Reset button. The green status LED and orange network LED will begin to flash fast. Continue to hold the Setup button down for 10 seconds. After 10 seconds, the LEDs will stop flashing at which point the Setup button can be released. All settings will be changed back to the factory state and the device will restart. Any firmware updates made to the device will be preserved.
Warning
Returning the device to factory defaults will remove all network settings, rendering remote updates impossible.
Passwords The Senquip QUAD is shipped, pre-loaded, with a random password that prevent unauthorised connection to the Wi-Fi hotspot and prevent access to the built in webserver. The default passwords are printed on a label that can be found under the cover.
The default passwords can be found under the lid
The label contains two sections:
General information about the Senquip QUAD such as the part number, identification number, Wi-Fi SSID and the IP address of the webserver
A removable section that contains the part number, identification number, webserver password (setup password), Wi-Fi SSID and Wi-Fi password. This section should be removed and stored securely. It is recommended that the passwords be changed as soon as possible using the webserver or the Senquip portal.
Label with general information and passwords
A label with the device ID is placed on the Senquip QUAD base to prevent bases and lids being misplaced.
Matching device ID label
Take note of the Wi-Fi and setup passwords as you will need them to continue with the setup. In the example above, the Senquip QUAD identifier is DE9032030, the Wi-Fi password is hjg3iplg and the setup password is QvjSF3jk.
Setup Mode Setup Mode allows initial customer configuration via the integrated web-server. To enter setup mode, power the device and wait for the green light to go solid and then press the Setup button.
In setup mode, an integrated Wi-Fi Access Point (AP) is enabled through which the installer can access the built in web-server. The web-server allows for initial setup using a web based interface, similar to setting up a home router. In this mode, a user can connect to the device using any computer, tablet or mobile phone that has Wi-Fi and is loaded with a browser. After the device is connected to a network, changes can be made remotely using the Senquip Portal.
Note
The Senquip QUAD Wi-Fi Access Point is 2.4GHz only
If connected to external power, the device will remain in setup mode as long as the lid is open. If no external power is available, the device will enter sleep mode after 10 minutes of no activity. To re-enable setup mode, press the Setup button again for 2 seconds. Setup mode will be exited once the lid has been closed for more than 10 seconds.
Note
A shadow over the light sensor can make the device exit setup mode. It is easier to configure the device from the Senquip Portal once a network connection has been established.
To connect to the Senquip QUAD, search for available Wi-Fi networks on your Wi-Fi enabled device. The device will advertise itself as QUAD-xxxxx, where xxxxx represents the last 5 digits of the device identifier. The device identifier as well as password and other information can be found on a sticker under the lid. In the example below, using an Android phone, the Senquip QUAD can be seen to be advertising itself as QUAD-32030, where 32030 are the last five digits of the device identifier.
Search for Wi-Fi networks
Select the Senquip QUAD’s advertised Wi-Fi network name, QUAD-32030 in this example, and enter the Wi-Fi password found under the lid, hjg3iplg in this example. When you press connect, your Wi-Fi enabled device will connect to the device Wi-Fi hotspot. Being connected to the Wi-Fi hotspot does not allow you to view or change any data yet. To view and change data, you need to login to the device webserver.
Enter the Wi-Fi password
Once you are connected to the Wi-Fi hotspot, to access the web-server, open your preferred web-browser (Senquip recommends Chrome) and in the address bar, type 192.168.4.1 and press enter. Your browser will open the web-server password entry page. For username, type in admin; the setup password can be found on the sticker under the lid of the device. In the example above, the password is QvjSF3jk. Remember to change this password as soon as possible using the Admin tab in the web-server.
Accessing the web-server
Note
Performing a factory reset will reset the passwords to their defaults as found under the lid.
If you have entered the username and password correctly, you will now have access to the device web-server. From the web-server, you will be able to view current data, make configuration changes and perform software updates.
