X2 and X2 4G/LTE limitations

Technical Limitations & Usage Details

The HUBBOX Connect X2 and X2 4G/LTE series are high-performance industrial routers. To ensure hardware longevity and operational reliability, users must strictly adhere to the following electrical and environmental constraints.

1. Power Supply and Voltage Constraints

Incorrect power application is the leading cause of hardware failure in industrial gateways.

Voltage Range: The system requires a stable 24V DC input. Connect the positive lead to Pin 5 (+) and the negative lead to Pin 6 (-).
Reverse Polarity: While some protection is built-in, sustained incorrect polarity during installation can cause irreversible damage to the internal power management IC.
Line Noise: In heavy industrial environments, significant voltage fluctuations outside the standard operating window can trigger emergency reboots or cause data corruption during write cycles.

2. Physical Port & Bandwidth Limitations

Ports are optimized for industrial automation rather than high-speed consumer computing:

Ethernet Configuration: Features two 10/100 Mbps ports. One is a fixed LAN; the other is a software-switchable WAN/LAN. Throughput is governed by the onboard CPU's encryption processing capacity.
USB 2.0 Standard: The USB port is intended for serial converters or low-power peripherals. It is not designed for high-speed storage arrays or power-hungry external drives.
Micro HDMI Output: Designed for local diagnostics and Kiosk mode. It supports basic monitoring but is not intended for heavy graphical rendering or 4K video playback.

3. Wireless & RF Environment Management

RF performance is highly sensitive to shielding and installation quality:

SMA Antennas: Antennas must be securely tightened to the SMA connectors before powering on. Operating the 4G/LTE module without an antenna can lead to hardware overheating and permanent radio damage.
Signal Attenuation: If the HUBBOX is housed inside a metal cabinet, cellular and Wi-Fi signals will be blocked (Faraday Cage effect). The use of external pigtail cables and roof-mounted antennas is mandatory for such installations.

4. Digital I/O (DI/DO) Electrical Limits

Warning: The DI/DO pins on the terminal block are signal-level only.

Pin 7 (DI): Designed for 24V dry contact or transistor signals.
Pin 8 (DO): This is a low-current output. Never connect inductive loads (motors, large solenoids) directly. You must use an interposing relay to switch high-current circuits.

5. Software & Network Constraints

Default IP Conflict: The factory IP is 192.168.24.254. Ensure no other device on the LAN side shares this address to prevent ARP conflicts and management lockout.
Authentication: The default credentials are hubbox / hubbox. Security policy mandates an immediate password change upon deployment to prevent unauthorized remote access.

Security Note: All Hubbox communications utilize 2048-Bit RSA Encryption. Ensure your firewall allows outgoing traffic on the necessary ports for the encrypted tunnel to establish correctly.
