The EPC-302E is a fanless industrial box PC built around five Intel I210 Gigabit LAN ports. Most box PCs ship with one or two network ports; five lets a single chassis act as a network node in its own right — routing between production cells, isolating a machine network from the plant network, or aggregating several device subnets without an external switch. Alongside the five LAN ports it carries 4× RS232 plus 1× RS485 on DB9, 6× USB and HDMI + VGA dual display.

The usual patterns are network segmentation (one port per production cell or machine group, so a fault or broadcast storm in one segment cannot reach the others), gateway and protocol-conversion nodes (the unit sits between device subnets and the plant network), machine/plant separation (machine traffic on one port and the MES or SCADA link on another, with no router in between), and link redundancy where a spare port takes over a failed path. All five are 10/100/1000M Intel I210 controllers, the same silicon used across the CESIPC range.

The Intel I210 is the industrial-grade Gigabit controller CESIPC uses across the range. Compared with consumer-grade controllers it holds its link under electrical noise and wide temperature, and it is the controller whose drivers are tested for the long-term support cycles industrial software vendors ship. On a unit whose whole purpose is moving network traffic, that matters more than on a display terminal.

4× RS232 plus 1× RS485, all on DB9. The dedicated RS485 port is the practical difference from the rest of the chassis family: RS485 is what most multi-drop field buses use, so a single twisted pair can carry a chain of meters, inverters or sensors rather than one device per port. If your site mixes RS232 instruments with an RS485 bus, this unit covers both without an external converter.

The base build is an Intel® Core™ 12th Gen i3-1215U. Three factory builds are orderable: C10.03.06.001 i3-1215U with 8GB, C10.03.06.002 i5-1235U with 8GB, and C10.03.06.003 i7-1255U with 16GB — all with a 256GB SSD. The enclosure, the five LAN ports and the serial ports are identical across all three.

Memory is DDR5, 8–32GB and storage is 2× M.2 SSD. Two M.2 slots let the operating system and the log or traffic archive sit on separate drives, which is useful on a gateway that must keep recording while the system disk is serviced.

It is completely fanless — no fan, no filter, and no air path drawing dust, metal filings or oil mist across the boards. Operating temperature is 0–50 ℃ as standard with −40–70 ℃ optional; storage is −10–60 ℃ and humidity 10%–90% non-condensing.

337 (W) × 160 (D) × 47.5 (H) mm and 2.3 kg, in high-strength aluminium alloy with wall mount and VESA mount. Power comes in through a 1× 3-pin pluggable terminal block at 12V DC, with 9–36V DC available as an option for vehicles, battery-backed systems and unstable plant supplies. Startup is switchable between AT and ATX so the unit can resume automatically when plant power returns.

CE, FCC and BIS according to EN 55032 and EN 55035. ODM covers custom BIOS, boot-on-LOGO and OEM branding from the factory, on the same chassis and the same part numbers. Supported systems are Windows 10 / 11 and Linux Ubuntu.
