Collection: Bluetooth Serial Adapters

Replace fragile, awkward serial cables with a wireless link. The CHIPSEN RCPORT-TD400 Series of Bluetooth Low Energy (BLE) serial adapters gives your RS232, RS422, or RS485 equipment a drop-in wireless connection — plug one in, pair it, and start transmitting serial data wirelessly up to 1,000 feet away. No firmware development, no embedded programming, and no configuration software required for basic use.
All four adapters in this collection share the same Bluetooth engine and operating modes — including 1:1 Auto Pairing, 1:1 Node Switching, and 1:7 Multi Connection — and can wirelessly communicate with each other regardless of connector type. They differ in connector, power source, and serial protocol, so use the table below to find the right one for your equipment.
| Model | Connector | Serial Protocol | Power | Best For |
|---|---|---|---|---|
| RCPORT-TD400 | DSUB9 (Female) | RS232 | 5–24V DC | General-purpose RS232 equipment and test gear |
| RCPORT-TD410 | DSUB9 (Female) | RS232 | 5–24V DC or built-in battery | Portable or mobile RS232 setups without external power |
| RCPORT-TD420 | USB-A | RS232 (virtual COM port) | USB-powered | Laptops and PCs with no built-in serial port |
| RCPORT-TD450 | DSUB9 (Male) | RS422 / RS485 | 5–24V DC | Industrial and multi-drop equipment |
Note: These adapters use Bluetooth Low Energy (BLE) — not Bluetooth Classic — and will only pair with other BLE-capable devices, including each other. For full setup, wiring, and pairing instructions, see the RCPORT-TD400 Series User Guide.
