Installation
Opening the Box
The QUAD-C3 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-C3
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-C3 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-C3. 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 Installation
The QUAD-C3 supports three SIM options:
SoftSIM - A software SIM that requires no additional hardware. SoftSIM availability depends on network support and service availability. SoftSIMs offer high reliability and simplified deployment. Contact Senquip for more information.
eSIM - Provision is made on the PCB for a customer-supplied MFF2 eSIM component. eSIMs provide excellent reliability in high-vibration environments. Contact Senquip for more information.
Nano-SIM - A Nano-SIM holder is provided for customers wishing to use their own SIM cards. Nano-SIMs offer the greatest flexibility and network choice.
If mobile communications are required and a SoftSIM or eSIM is not fitted, a Nano-SIM card must be installed. The QUAD-C3 supports both 1.8V and 3.3V Nano-SIM cards.
SIM card sizes
Note
If your QUAD-C3 is fitted with a SoftSIM or eSIM, a Nano-SIM card is not required.
To access the Nano-SIM holder, open the enclosure lid. The SIM holder is a push-push type. Push the SIM card fully into the holder to install it. To remove the SIM card, push it gently and release. The SIM card will eject from the holder.
Identifying the SIM card slot
To install a Nano-SIM card, orient it with the chamfered corner in the bottom-right position and push it fully into the SIM holder until it clicks into place.
Correct orientation of a Nano-SIM card
The enclosure lid incorporates a retention feature that helps secure the SIM card in harsh operating environments. Ensure the enclosure is fully closed and secured after installing the SIM card.
SIM card retention feature
After installing or removing a SIM card, it is recommended that the QUAD-C3 be reset so that the modem can detect the change.
Wiring Guide
The Senquip QUAD is fitted with a 14 way 3.5mm pitch colour coded 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.
If using ferrules, a square crimp is preferred as it provides maximum contact area and reduces risk of the contact becomming jammed in the connector.
Square crimp ferrules are preferred
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.

Gland assembly instruction
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.

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 exact firmware number 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 QUAD-C3 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
Each QUAD-C3 is supplied with unique factory-generated credentials that protect access to the device and simplify commissioning.
The credentials are generated using a cryptographically secure random number generation process and are unique to each device.
The device is supplied with a credentials card located inside the enclosure containing:
Device ID
Setup Password (SETUP PASS)
Wi-Fi Access Point Password (WIFI PASS)
Quick Add QR code
Quick Start Guide QR code
Device credentials card
The Device ID uniquely identifies the device within the Senquip Portal.
The Setup Password is used to access device settings through the Senquip Connect App or device webserver while the device is in setup mode. The Setup Password may also be used to establish administrative access to a device if no administrator has yet been assigned.
The Wi-Fi Password protects access to the device’s Wi-Fi Access Point when local wireless configuration is required.
The Quick Add QR code contains the Device ID and Setup Password, allowing an authenticated Senquip Portal user to add the device to their account with a single scan.
The Quick Start Guide QR code links to the latest installation and commissioning instructions for the device.
Warning
Store the credentials card in a secure location. Anyone with access to the Device ID and Setup Password may be able to establish administrative access to the device.
Password Management
Authorised administrators may change the Setup Password and Wi-Fi Password through the Senquip Portal.
If a password is forgotten, an administrator may retrieve the current password through the Senquip Portal following identity verification.
Factory Reset
A factory reset restores device settings to their factory defaults, including the factory default passwords.
A factory reset does not change device ownership, user permissions, or the device identity recorded by the Senquip Cloud.
Administrative Recovery
If all administrator accounts are inadvertently removed from a device, administrative access may be re-established using the Setup Password.
Where appropriate verification can be completed, Senquip may also assist in restoring the original administrator account associated with the device.
Setup Mode
Setup Mode enables local configuration of the QUAD-C3 using either the Senquip Connect App via Bluetooth or the device’s embedded web server via Wi-Fi.
Entering Setup Mode
To enter Setup Mode, power the QUAD-C3 and wait for the green Status LED to become solid. Press the Setup button. When the green Status LED starts flashing, the device is in Setup Mode.
If connected to external power, the QUAD-C3 will remain in Setup Mode while the lid is open. If external power is not available, the QUAD-C3 will enter sleep mode after 10 minutes of inactivity. To re-enter Setup Mode, press the Setup button again for 2 seconds.
Setup Mode is exited once the lid has been closed for more than 10 seconds.
Configuring the Device
Once the QUAD-C3 is in Setup Mode, local configuration can be performed using either:
Senquip Connect App (recommended) - connects to the QUAD-C3 via Bluetooth.
Embedded Web Server - connects to the QUAD-C3 via its Wi-Fi access point using a web browser.
For detailed instructions on using either method, see First Connection.
