How to Install Digi EX15

Installing the Digi EX15 is designed to be straightforward, so you can deploy quickly and minimize downtime. Before you begin, gather the device, the two SIM cards from your mobile operators, a suitable power supply, and access to a computer or laptop for initial configuration. The steps below outline a typical setup workflow that works for most SMB deployments, whether you’re equipping a retail store, a kiosk, or a mobile vehicle installation.

• Power down and prepare: Ensure you have a clean workspace and the correct power adapter. Confirm you have two active SIM cards properly provisioned with data plans and roaming enabled if required.
• Insert SIM cards correctly: Open the EX15 SIM slots and insert each SIM in its designated slot, following the device’s labeling. Confirm SIMs are fully seated and that the device recognizes both profiles.
• Connect network cables and power: Attach the Ethernet cable to the EX15’s WAN/Internet port, connect the other end to your modem or network source, and plug in the power supply to boot the unit.
• Access the management interface: On a computer connected to the EX15 (via Ethernet or Wi‑Fi), open a web browser and navigate to the device’s default IP address as documented in the quick start guide. Use the default admin credentials to log in, then immediately change the password for security.
• Configure WAN failover and SIM profiles: In the router’s web interface, set the primary WAN connection (e.g., SIM 1) and enable failover to the secondary SIM (e.g., SIM 2) or Ethernet when the primary path is degraded. Save settings and apply the changes.
• Set up Wi‑Fi and network segmentation: Create your Wi‑Fi network(s) with clear SSIDs, strong WPA2/WPA3 security, and appropriate guest network settings if needed. Consider separating guest traffic from critical operational traffic to protect sensitive data.
• Enable security controls and VPN access: Configure firewall rules to protect payment terminals and devices, and establish VPN tunnels or VPN passthrough as required to connect to corporate networks or cloud services.
• Activate Digi Remote Manager (DRM): If you plan to manage devices remotely, enroll the EX15 in DRM, link it to your account, and apply a fleet-wide configuration profile to simplify ongoing management and monitoring.
• Update firmware and perform a quick test: Check for the latest firmware and apply updates. Run a quick connectivity test by simulating a WAN outage to confirm the failover works as intended, and verify that connected devices regain access promptly.
• Document and deploy: Record the network configuration details, SSIDs, passwords, and failover rules for IT records, and deploy the unit to its operating location, ensuring mounting or placement complies with safety and environmental requirements.

Frequently asked questions

Q: What is the Digi EX15 best used for?

A: The Digi EX15 best serves scenarios that require reliable, resilient connectivity in SMB environments. It is ideal for retailers needing uninterrupted POS connectivity, kiosks requiring consistent guest Wi‑Fi, remote sites needing backup communication paths, and mobile deployments where dual-network redundancy improves uptime. Its dual-SIM capability and integrated routing simplify deployment while reducing the risk of revenue loss due to network outages.

Q: How does dual SIM failover work on the EX15?

A: Dual SIM failover automatically monitors the health of the primary connection and switches to the secondary carrier or SIM when the primary link deteriorates. This process minimizes downtime for critical applications, helping to keep payment terminals, ERP integrations, and IoT devices online even in areas with unstable cellular coverage. You can configure the preferred failover behavior and carrier profiles through the device’s management interface or DRM policies.

Q: Can the EX15 provide Wi‑Fi for customers and staff?

A: Yes. The EX15 includes built-in Wi‑Fi to support wireless devices such as tablets, POS tablets, staff devices, and guest networks. You can create separate SSIDs and apply security settings to protect sensitive business networks while delivering convenient guest access in retail environments or service points. Wireless performance will vary with the environment, but the device is designed to deliver dependable coverage in small to medium spaces.

Q: Is remote management available for multiple EX15 units?

A: Absolutely. The EX15 is compatible with Digi Remote Manager (DRM), a cloud-based management platform that lets IT teams monitor, configure, update firmware, and receive alerts across a fleet of devices from a single console. DRM simplifies onboarding of new units, standardizes configurations across locations, and provides visibility into network health, data usage, and connectivity events, which helps you proactively address issues before they impact users.

Q: What security features protect payments and customer data?

A: The EX15 includes integrated firewall functionality and supports VPN connectivity to protect data as it traverses the network. You can define access controls, segment networks, and use encrypted tunnels to corporate resources. For retailers and SMBs handling card payments or personal data, these security features help meet best-practice requirements and reduce exposure to common threats in wired and wireless environments.
