Technical FAQ
1. Can I connect the SBOX-2321 to a 24 VDC cabinet power supply?
Yes. The terminal-block input accepts 9–36 VDC, including a nominal 24 VDC supply. Before wiring, verify the supply polarity and ensure its operating voltage remains within this range. The input includes overcurrent and overvoltage protection.
2. What do I need to connect two displays?
Use the DisplayPort 1.4 output and the DVI-D output. The DVI-D connection requires a single-link cable. Select displays and cables that match these interfaces; the system does not provide a native HDMI output.
3. Are the SIM card slots enough to enable LTE or 5G connectivity?
No. Cellular connectivity requires an optional compatible LTE or 5G module, suitable antennas, and an activated SIM with a data plan. The listed cellular expansion option uses the M.2 3042/3052 Key B slot. The system provides two SIM slots, but automatic network switching should be confirmed for the selected modem and software configuration.
4. How do I connect CAN bus equipment?
Add the optional mPCIe CAN bus module. CAN connectivity is an expansion option rather than a standard onboard interface. Specify the required CAN interface and external connection when ordering so the module and connection arrangement can be confirmed.
5. Can the SBOX-2321 operate at 70°C without cabinet ventilation?
The published −40°C to 70°C operating range requires airflow of 0.6 m/s. Fanless cooling does not remove this airflow condition. Check the temperature and airflow at the installation location, and include the selected memory, storage, and expansion modules in thermal validation.
