USB cable DELOCK 63983 — single pack, standard USB connection

DELOCK 63983 is a USB cable supplied as a single unit that provides a standard USB connection for data transfer and charging between compatible devices. This specific variant is a USB 2.0 Type-C to UART TTL (5 V) adapter with an integrated 6-pin header carrying TX, RX, CTS, RTS, VCC (5 V) and GND signals. With a 1.8 m cable length it is intended for bench work, development and field use where a USB host must interface directly with TTL-level serial devices and, when appropriate, supply 5 V to the target board.

Advantages

The adapter combines USB 2.0 Type-C connectivity with standard 5 V TTL serial levels, enabling direct serial communication without the need for a separate power converter. The exposed 6-pin header includes hardware flow control lines (CTS and RTS) and a dedicated 5 V output to power compatible target devices. The 1.8 m length offers flexibility in device placement and reduces mechanical strain near the host connector during testing or development.

Suitable for

• Accessing serial consoles on routers, single-board computers and embedded systems
• Microcontroller development and debugging using TTL-level UART
• Firmware flashing and bootloader interaction that require a serial connection
• Hardware testing and diagnostics where CTS/RTS flow control is used
• Prototyping scenarios where a 5 V supply from the adapter is convenient

Key specifications

• Interface: USB 2.0 Type-C to UART TTL
• UART signal lines: TX, RX, CTS, RTS, VCC (5 V), GND
• Signal voltage level: 5 V TTL for data and VCC output
• Cable length: 1.8 m
• Connector: 6-pin header for direct pin access

How to use

Connect the Type-C plug to a USB host port on a PC or compatible device that supports USB 2.0. Attach the 6-pin header to the target device, ensuring correct alignment so TX of one side connects to RX of the other and that GND is shared. If power from the adapter is required, connect the VCC (5 V) pin to the target only after verifying the target accepts a 5 V supply. Launch a terminal emulator or serial communication program on the host, open the appropriate COM/serial port and set the required baud rate and serial parameters. Enable hardware flow control in the software when using CTS/RTS lines for reliable transfers.

Recommendations

Before connecting, verify the target device’s acceptable logic and supply voltages; if the device requires 3.3 V logic, use a level shifter or an appropriate adapter. Keep the cable free from sharp bends and avoid exposure of connectors to moisture. When using flow control, configure the terminal to match the target device’s RTS/CTS behaviour to prevent communication issues.
