Quick Answer for CWWK Industrial Box PC Users
The CWWK CW-C42 industrial box PC is a compact fanless computer powered by an Intel Celeron J4125 quad-core processor. It supports up to 16GB DDR4 memory, dual Gigabit LAN, two configurable RS232/RS485 serial ports, mSATA and SATA storage, Mini PCIe expansion, GPIO and a hardware watchdog.
With 12–19V DC input, automatic power-on support and an operating temperature range of -20°C to 60°C, the CW-C42 is suitable for industrial control, equipment communication, embedded terminals and unattended computing systems.
CW-C42 Industrial Box PC Product Overview
Intel J4125 Processor for Fanless Industrial Computing
The CW-C42 is equipped with an integrated Intel Celeron J4125 quad-core processor. Intel UHD Graphics 600 supports local display without requiring a separate graphics card.
The standard display configuration includes HDMI and VGA. Depending on the selected hardware configuration, a dual HDMI version may also be available.
DDR4 and mSATA Storage for Embedded Box PCs
One DDR4 SO-DIMM slot supports up to 16GB of single-channel DDR4-2400 memory.
The CW-C42 includes one full-size mSATA slot and one SATA 3.0 connector with transfer speeds of up to 6Gbps. The mSATA SSD can be used as the system drive, while the SATA interface can connect an additional SSD or hard drive for local files, application data and system logs.
Dual LAN and RS232/RS485 Industrial Connectivity
The CW-C42 supports two Realtek RTL8111H Gigabit Ethernet ports with Wake-on-LAN and PXE Boot.
Two external DB9 COM ports operate as RS232 interfaces by default. COM1 and COM2 can be configured for RS485 operation through onboard jumpers, enabling communication with compatible PLCs, industrial controllers, barcode scanners and measuring equipment.
Fanless Industrial Box PC Cooling and Chassis Design
The CW-C42 uses a fanless cooling structure with a bottom-mounted heatsink that transfers processor heat to the aluminum chassis. This design reduces noise, dust intake and mechanical maintenance.
The platform also provides four GPIO input/output channels, a hardware watchdog timer, AT and ATX power modes and automatic startup after power restoration.
Its 120 × 120mm motherboard platform supports 12–19V DC input and an operating temperature range of -20°C to 60°C.

CW-C42 Industrial Box PC FAQ
Does the CW-C42 include the Intel J4125 processor?
Yes. The Intel Celeron J4125 processor is integrated into the CW-C42 motherboard. A separate desktop CPU is not required.
How much DDR4 memory does the industrial box PC support?
The CW-C42 provides one DDR4 SO-DIMM slot and supports up to 16GB of single-channel DDR4-2400 memory.
Memory may not be included with every configuration. Check the selected option before ordering.
Does the CW-C42 support RS232 and RS485 devices?
Yes. The two DB9 ports operate as RS232 interfaces by default. COM1 and COM2 can be switched to RS485 mode through onboard jumper settings.
Can the CW-C42 connect to PLCs and industrial controllers?
The COM ports, Gigabit Ethernet interfaces and GPIO channels allow the CW-C42 to connect to compatible PLCs, controllers, sensors and industrial equipment.
Compatibility depends on the interface, protocol, operating system and installed software.
What storage devices can be installed in the CW-C42?
The CW-C42 supports one full-size mSATA SSD and one additional SATA 3.0 storage device. Both interfaces can be used together.
Does the CW-C42 support WiFi or 4G connectivity?
Yes. The Mini PCIe slot supports compatible WiFi or 4G modules. Module size, antenna connections and cellular frequency bands should be confirmed before ordering.
Can dual LAN, rear USB 2.0 and 4G be used at the same time?
The standard dual-LAN configuration disables the two optional rear USB 2.0 ports because LAN2 and those USB ports are mutually exclusive.
Installing a Mini PCIe 4G module also makes the internal USB 2.0 header unavailable.
Does this fanless industrial PC support automatic power-on?
Yes. Automatic startup after power restoration can be enabled through the onboard AT-ATX jumper. The CW-C42 also includes a hardware watchdog for unattended system recovery.
