USB cable DELOCK 63986 — single pack, standard USB connection

DELOCK 63986 is a single-pack USB cable that functions as a USB 2.0 Type-A to UART TTL converter with an integrated 1.8 m cable. It converts a standard USB host port into a 6-pin TTL-level serial interface providing TX, RX, CTS, RTS and a dedicated 5 V output. The cable supports data transfer over USB 2.0 and can supply power to compatible TTL devices within the USB host’s available current limits, making it suitable for bench work, development and installation inside enclosures.

Advantages

The integrated converter eliminates the need for a separate serial adapter and can power many target devices directly from the USB 5 V output when device current requirements permit. Hardware flow control lines (CTS and RTS) are exposed for reliable serial communication in applications requiring handshaking. The 1.8 m cable length gives additional reach for comfortable working on development boards or positioning devices inside cases without extra extensions.

Suitable for

• Firmware flashing and bootloader access on microcontrollers and development boards
• Serial console access for debugging routers, single-board computers and embedded systems
• Data exchange with sensors, modems and industrial controllers using TTL UART levels
• Prototyping and programming of microcontroller-based projects

Key specifications

• Interface: USB 2.0 Type-A (host) to UART TTL
• Connector: 6-pin header with TX, RX, CTS, RTS and 5 V output
• Signal level: TTL (5 V output available)
• Cable length: 1.8 m integrated cable
• Power: 5 V output supplied from USB host (subject to host current limits)

How to use

Insert the Type-A plug into a USB host port on a computer or other USB host device. Connect the 6-pin header to the target device’s UART pins, making sure to align TX to RX and RX to TX; connect CTS and RTS if hardware flow control is required. If the target device can be powered from USB, use the 5 V output within the host’s current capability. Install any necessary drivers on the host if the converter is not recognized automatically, then open a serial terminal or programming tool configured with the correct baud rate and serial parameters.

Recommendations

Confirm voltage levels and pinout compatibility before connection to avoid damage. Do not draw more current from the USB 5 V output than the host port permits. Observe proper grounding and electrostatic discharge precautions when handling sensitive electronics.
