USB-to-DB25 serial adapter for TNCs

This Vszerda cable uses an FTDI FT232RL chip to connect a USB port to RS-232 equipment with a DB25 male connector. It targets radio operators linking Kantronics KPC2 or KPC-3+ terminal node controllers and ARM Debian single-board computers. The 1.8 m cable carries only TXD, RXD, RTS, CTS and ground with software handshaking.

Verify RS-232 pinout and driver support

Confirm the target device expects RS-232 signalling on a DB25 shell and not IEEE-1284 parallel protocol. Ensure the host runs Windows 10, 8.1, 7, Vista, XP, 98, Server 2003, 2008, CE 4.2+, Linux, Mac OS X/9/8 or Android on 32- or 64-bit architecture. Download the FTDI VCP driver before installation.

Steady activity indication under load

Indicator LEDs inside the transparent USB hood show traffic during long TNC sessions on Raspberry Pi or similar platforms. The moulded connector and fixed 1.8 m length avoid intermittent contact when the link runs continuously. No parallel-printer signalling is present, so sustained data streams stay on the three-wire RS-232 path.

Questions about this item

Does the 1.8m cable include everything needed to connect a USB port to a DB25 serial device?

The package contains one FTDI USB to DB25 cable with the FT232RL chip built into the USB connector. No extra adapters or power supplies are required.

Which DB25 pinout does this 1.8m cable use for RS232 communication?

It uses a three-signal layout with software handshaking: TXD on pin 2, RXD on pin 3, RTS on pin 4, CTS on pin 5 and GND on pin 7.

Will the FT232RL chip in this 1.8m cable work with a 64-bit Linux system and a Kantronics KPC-3+?

Yes, the cable supports 64-bit Linux and the supplier confirms successful use with a Kantronics KPC-3+ on a Raspberry Pi running Debian.
