The EPC-202B is a fanless industrial box PC built around port count: ten USB ports and seven serial ports. Standard box PCs typically give you four or six USB and one or two COM. The EPC-202B is for stations where the peripheral list keeps growing — cameras, scanners, scales, label printers and legacy controllers — and where the cabinet has no room left for powered hubs and USB-to-serial stacks.

Ten in total: 6× USB 2.0 and 4× USB 3.0, all Type-A. The USB 3.0 ports are the ones to give to cameras or fast storage; the USB 2.0 ports suit scanners, indicators, printers and dongles. Because Type-A is used throughout, standard cables and adapters fit without conversion, and a service keyboard can stay connected permanently.

Seven: 4× RS232 and 3× RS485, all on standard DB9 sockets. The three RS485 ports are the important number — RS485 is the multi-drop standard, so one port can carry a chain of meters, inverters or sensors on a single twisted pair. Three of them means three separate field buses can be driven without any external converter.

3.7 kg against 2.3 kg for the same footprint. The difference is the ten USB sockets and seven DB9 shells plus their termination. That extra hardware is what keeps the connectors on the chassis itself instead of on an external breakout board — which matters in a cabinet where a breakout board would need its own mounting, its own cable and its own failure mode.

Peripheral-heavy and serial-heavy stations: test and inspection benches with cameras plus instruments, packaging and labelling lines with scanners, printers and weighing terminals, laboratory benches with analysers and meters, and retrofit cabinets where an old controller had a stack of serial devices and the replacement has to take them all on.

The base build is an Intel® Core™ 12th Gen i3-1215U running at 1.2–4.4 GHz. Three standard factory builds are orderable — i3-1215U, i5-1235U and i7-1255U — with part numbers C10.03.04.001, C10.03.04.002 and C10.03.04.004. The ports, the chassis and the mounting are identical across all three.

4–32GB DDR5 with a 1× mSATA SSD. DDR5 matters here because a station running several cameras or instrument feeds is bandwidth-bound before it is compute-bound, and 32GB leaves room for image buffers and a local database alongside the application.

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

12V DC on a 3-pin pluggable terminal block, with 9–36V DC optional and startup switchable between AT and ATX. Networking is 2× Intel I210 Gigabit LAN plus optional 4G and Wi-Fi/Bluetooth. Certifications are CE, FCC and BIS to EN 55032 and EN 55035, with ODM support for custom BIOS, boot-on-LOGO and OEM branding. It runs Windows 10 / 11 and Linux Ubuntu.
