UPC-309C 4G Industrial PC

The UPC‑309C is a 4G‑enabled fanless industrial PC purpose‑built for applications requiring wireless connectivity in remote or mobile environments. Key differentiators include:

• Built‑in 4G/LTE with SIM card slot — Integrated LTE module enables high‑speed wireless communication without relying on fixed networks. Supports external antennas for weak coverage areas and optional Wi‑Fi hotspot functionality. This eliminates the need for external cellular gateways or USB dongles, reducing failure points and simplifying deployment in transportation monitoring, roadside units, and remote oil/gas sites where wired internet is unavailable.

• Fanless passive cooling — Uses a thermally engineered 6061 aluminum chassis as a passive radiator, eliminating dust intake, bearing failure, and scheduled fan replacement. Ideal for dust‑prone transportation enclosures and 24/7 unattended deployments in wayside cabinets and vehicle compartments.

• LEGO MODE (BlockCore™) modular architecture — Built on CESIPC’s BlockCore™ platform, supporting i‑Door expansion modules (CAN, 5‑port LAN, isolated serial, 5G) without custom PCB development.

• 4 COM ports (2×RS232 + 2×RS485) — Interfaces with legacy industrial sensors, PLCs, LED signs, toll collection equipment, and industrial meters. The UPC‑309C shares the same chassis and I/O layout as the EPC‑30XA and EPC‑40XA, enabling mixed‑fleet deployments with common mounting and cabling.

• Industrial‑grade reliability — Supports 0–50°C standard operating temperature (-40~70°C optional), 9–36V DC wide‑range input, and dual Intel® I210 Gigabit Ethernet for network reliability.

• SafeCore™ power‑loss protection — Prevents OS/file corruption during sudden power loss, with one‑reboot recovery. Critical for mission‑critical roadside and remote monitoring applications where site visits are costly.

Standard commercial PCs lack these industrial‑grade features and typically fail within months in 24/7 unattended or dust‑prone environments.

The UPC‑309C addresses a critical pain point in remote and mobile deployments — the need for external cellular gateways or USB dongles, which introduce additional points of failure, cabling complexity, and power management issues. Built‑in 4G with SIM card slot eliminates these risks. Key applications include:

• Smart transportation & roadside infrastructure — Connected traffic signal controllers, variable message signs (LED boards), electronic toll collection (ETC) terminals, bridge health monitoring systems, and highway information displays. The 4G connection enables real‑time status updates and remote configuration without trenching fiber or copper. Dual Intel I210 Gigabit Ethernet ports also support direct connection to local IP cameras and sensors.

• Remote monitoring & industrial IoT — Water treatment plants, oil & gas wellheads, utility substations, and pipeline monitoring stations. The UPC‑309C collects data from field sensors (via 4 COM ports) and transmits it to central SCADA or cloud platforms over 4G — eliminating the need for satellite or costly private network infrastructure.

• Vehicle telematics & fleet management — Public transit buses, logistics trucks, and service vehicles. The 4G connection provides real‑time GPS tracking, engine diagnostics, and cargo condition monitoring. The 9–36V wide‑range input tolerates vehicle voltage fluctuations, and the fanless design withstands shock and vibration in mobile installations.

• Video surveillance & security — Remote security cameras at construction sites, parking lots, and critical infrastructure. The 4G connection enables real‑time video streaming and event‑triggered alerts without fixed broadband.

• Precision agriculture — Connected tractors, irrigation controllers, and soil monitoring stations. Data collected from sensors is transmitted via 4G to farm management platforms for real‑time decision support.

• Field service & mobile workstations — Utility inspection crews, emergency response vehicles, and temporary construction site offices requiring on‑site computing with cellular backhaul. Optional Wi‑Fi hotspot functionality allows the UPC‑309C to share its 4G connection with nearby devices, simplifying temporary deployment.

Modular I/O via i‑Door (BlockCore™): The i‑Door smart expansion slot accepts function modules — CAN bus, 5‑port LAN, isolated serial, 5G — snapped in without wiring or chassis modifications. Ideal for field‑configurable applications where I/O requirements may evolve (e.g., adding CAN bus for vehicle integration).

External storage: 1× TF card slot for local backup, data logging, or system recovery.

BlockCore™ is CESIPC’s modular computing architecture that standardises interface, structure, power, and expansion across all products. For the UPC‑309C, BlockCore™ delivers:

1. LEGO MODE modular design philosophy — Based on LEGO brick construction principles, BlockCore™ creates a modular ecosystem where compute, I/O, and function boards can be configured like building blocks. This reduces custom development cost by up to 80% through standardised module libraries.

2. Standardised I/O expansion (i‑Door) — i‑Door expansion slots accept function modules (CAN, 5‑port LAN, isolated serial, 5G, GPIO) without custom PCB development. For roadside units requiring CAN bus for traffic signal integration, simply add the module — no hardware redesign.

3. Shared ecosystem across UPC series — The UPC‑309C uses the same i‑Core Board and expansion modules as other BlockCore™ industrial PCs. Standardise spares across mixed fleets of panel PCs, embedded PCs, and remote monitoring controllers.

4. Common chassis across product families — The UPC‑309C shares identical 337×160mm footprint and 53.2mm height with EPC‑30XA/40XA models. Mixed deployments across smart highways, rail, and industrial sites can use common cabinet cutouts and mounting brackets while deploying different I/O configurations per site. All support VESA 100×100mm and wall mount.

5. Extendable product lifecycle — BlockCore™ effectively extends product lifecycle, making investment in the UPC‑309C more cost‑efficient over the long term, particularly for large‑scale transportation and remote monitoring rollouts spanning multiple years.

SafeCore™ is CESIPC’s system‑level power‑loss protection architecture built into the UPC‑309C. In remote monitoring, transportation, and industrial environments, power interruptions are common — grid fluctuations, maintenance lockout/tagout, vehicle battery disconnects, or generator switching — events that corrupt OS files and data logs if power is removed abruptly. SafeCore™ provides:

• System‑level write protection — Blocks all unauthorised changes to the system; even after power failure, user error, or malware attack, system files automatically restore after reboot. For remote roadside units, this prevents tampering and ensures rapid recovery without a site visit.

• One‑reboot recovery mechanism — System crash or file corruption? Just reboot — the system returns to a healthy working state. No technical skills needed. Field technicians can restore service in minutes without IT support.

• Zero IT support required — Anyone on site (traffic maintenance crew, utility worker, facility manager) can recover the system with a simple restart, reducing downtime and on‑call IT costs in remote locations where sending an engineer is expensive and time‑consuming.

• Safe disk writes — Prevents fragmentation or file corruption during sudden power loss, ensuring data integrity for toll transaction logs, bridge sensor records, and quality control data.

Combined with auto power‑on recovery (the system automatically restarts when power returns), SafeCore™ is standard across all UPC‑309C models and works in tandem with TPM 2.0 hardware security for encrypted authentication and data protection.
