The Lightware CAB-SERIAL-USB-RS232-P180 is a 180cm USB to RS-232 adapter cable using an FTDI chipset with a Phoenix connector output. It provides reliable USB-to-serial conversion for control system integration with Lightware matrix switchers, extenders, and other RS-232 controllable AV equipment. The Phoenix connector mates directly with Lightware’s 3-pin RS-232 control port without requiring a separate adapter. Available from Creation Networks at .
RS-232 serial control remains the most common low-level protocol for AV device configuration and control: every Lightware matrix switcher, most third-party displays, and the majority of AV processors expose an RS-232 port. Modern control PCs and laptops carry no native RS-232 they require a USB-to-serial converter. The quality of that converter determines the reliability of the control connection.
FTDI-based adapters are the industry standard for reliable USB-to-RS-232 conversion. FTDI’s VCP (Virtual COM Port) drivers are included natively in Windows, macOS, and Linux, eliminating driver installation complexity. The chipset maintains stable baud rates and timing at all standard AV control speeds (9600, 19200, 38400, 115200 baud) without the timing errors and dropout issues common in cheaper silicon.
The Phoenix connector on the RS-232 end matches Lightware’s control port pinout directly. The 180cm length gives technicians comfortable reach from a laptop to rack-mounted equipment during programming and commissioning, without requiring an extension cable in most installations.

Why is the FTDI chipset important for AV control?FTDI chips implement the RS-232 timing standard accurately and are recognized by Windows, macOS, and Linux without requiring third-party driver installation. Cheaper chipsets (Prolific PL2303, CH340, counterfeit FTDI) have known issues with driver compatibility on modern Windows versions and timing instability at higher baud rates both of which cause unreliable control system behavior.What is the Phoenix connector and why does this cable use it?Phoenix (or Wago-type) connectors are screw-terminal or push-in connectors used for RS-232 control ports on Lightware and many professional AV devices. They provide a secure, tool-free connection without the bulk of a DB9 plug. This cable terminates in the Phoenix format that mates directly with Lightware RS-232 ports, eliminating the need for a DB9-to-Phoenix adapter.Can I use this cable with control systems from Crestron, AMX, or Extron?Yes. The USB end connects to any host with a USB Type-A port. The Phoenix RS-232 end controls any device with a compatible RS-232 Phoenix port, including Lightware and compatible third-party equipment. Verify the control processor’s RS-232 output connector type before use.Does this cable work on macOS and Linux without driver installation?Yes. FTDI VCP drivers are built into modern versions of macOS and Linux kernels. The adapter will enumerate as a COM/tty device automatically.Is 180cm long enough for rack work?For most configurations laptop on a desk or cart adjacent to a rack 180cm is sufficient. For deep rack environments or remote access scenarios, a USB extension cable can be added, or consider a serial-over-IP solution for permanent installations.Can this be used for permanent control system installations or is it only for commissioning?Both. The FTDI chipset and Phoenix connector make this suitable for permanent RS-232 control links where a USB host (embedded PC, control processor with USB host) provides the serial interface to Lightware equipment.
