SKU CH-XSTX-GJTE8

Four-channel USB serial debugger creates simultaneous RS485, RS232 and dual TTL COM ports with 12V 800mA, 5V 2A and 3.3V 200mA power outputs

  • Monitor four devices at once with one RS485, one RS232 and two TTL ports
  • Power sensors directly with 12V 800mA, 5V 2A and 3.3V 200mA outputs
  • Connect wires in seconds using tool-free lever terminals that resist vibration
  • Works driver-free on Windows and Linux including Raspberry Pi and Jetson Nano
  • USB Type-C interface provides high-speed data across all four channels

Four-channel USB serial debugger

The LORDWORLD RainbowLink provides four independent COM ports over a single USB-C connection. One channel speaks RS485, one speaks RS232 and two speak TTL so engineers can monitor multiple industrial devices at once without swapping cables. It is aimed at field technicians, PLC maintainers and IoT developers who need simultaneous access to mixed serial buses. The compact adapter draws power from the host and requires no external supply.

RS485 RS232 dual TTL conversion

Each of the four channels presents its own virtual COM port so software sees four distinct interfaces rather than a multiplexed stream. This means a Modbus RTU network on the RS485 line, a legacy console on the RS232 line and two logic-level sensors on the TTL lines can all be logged in parallel. The converter handles the protocol translation transparently and works driver-free on Windows and Linux including Raspberry Pi, LattePanda and Jetson Nano boards.

USB-powered 12V 5V 3.3V output

The unit derives 12V at 800mA, 5V at 2A and 3.3V at 200mA from the USB bus, letting you power attached sensors or PLC modules directly from a laptop in the field. Lever terminals make wiring tool-free and vibration-resistant for cabinet work. Because all power comes through the USB link, the adapter stays cool and silent with no fan or external brick required.

Questions about this item

What does having four independent COM ports let me do in a real setup?

You can monitor one RS485 device, one RS232 device and two TTL devices at the same time without switching cables or software windows.

What does the USB Type-C interface cap in practice?

The USB Type-C port supplies both data and the power needed to run the 12V 800mA, 5V 2A and 3.3V 200mA outputs from a single laptop connection.

What do the lever terminals need to fit or mount?

They accept bare wires pressed directly into the spring clamps, so no screwdrivers, crimps or DIN-rail brackets are required.
