Yes—but the documented four-port specification applies specifically to Beck IPC@CHIP SC1x3 controllers, including the SC123 and SC143. The SC1x3 hardware manual says it provides “four independent asynchronous serial ports.” That does not establish that every Beck IPC or Beckhoff controller has four ports, or that each port is a ready-to-wire RS-232 or RS-485 connection.
Which Beck controller has four serial interfaces?
The four-interface count is documented for the Beck IPC@CHIP SC1x3 family, including the SC123 and SC143. In its hardware manual, Beck describes these as four independent asynchronous serial ports. SC1x3 hardware manual
“Beck IPC web controller” alone is not a precise enough model description to establish a port count. Check the full model designation on the device and consult that model’s hardware manual before planning a connection or expansion.
What does “independent asynchronous serial ports” mean?
The SC1x3 manual describes UART capabilities for its four ports, including full-duplex transfer, selectable data format and handshaking, and separate port functions.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Data format: 7-bit or 8-bit data; odd, even, mark, space, or no parity; and one or two stop bits.
- Error handling: detection of parity, framing, overrun, and break conditions.
- Flow control: selectable CTS/RTS hardware handshaking.
- Per-port operation: separate maskable interrupts and independent baud-rate generators.
- Buffering and transfers: double-buffered transmission and reception, with DMA transfers identified in the manual.
- Baud-rate ceiling: the manual specifies a maximum baud rate of one-sixteenth of the CPU clock.
These are controller serial-interface capabilities, not a complete description of the physical connections available on a particular unit.
Does four ports mean four RS-232 or RS-485 connectors?
No. A count of UARTs does not by itself establish the connector type, pinout, signal voltage, or supported electrical standard. The SC1x3 material cited here specifies four asynchronous serial ports, but does not establish those physical details for each port. Check the SC1x3 pinout and hardware documentation before choosing cables, adapters, or line drivers.

Do not transfer wiring details from another model. A separate Beck IPC@CHIP SC12 hardware manual, for example, says the SC12’s asynchronous serial pins are TTL level and require external drivers such as a MAX232 for RS-232 or RS-485 levels. That is SC12-specific evidence, not a specification for the SC1x3. SC12 hardware manual

Serial-interface counts vary across controller models. The Beckhoff CX8080 manual describes two serial interfaces that can operate as RS-232 or RS-485; it is a different controller from the Beck IPC@CHIP SC1x3. Its specification illustrates why a four-port claim should not be generalized across Beck or Beckhoff product lines. CX8080 manual

What to verify before wiring or expansion
- Identify the exact model. Read the model designation from the controller, rather than relying on a broad “Beck IPC” description.
- Find its hardware manual and pinout. Confirm the number of interfaces and which physical pins or connectors correspond to them.
- Confirm electrical compatibility. Verify the documented signal level and whether the interface supports the standard your equipment requires, such as RS-232 or RS-485.
- Check operating constraints. Confirm whether the ports can be used simultaneously and review baud-rate and configuration limits for your model.
