RS232 to TTL serial converter - DB9, F/M
StarTech ID: IC232TTL
This RS232 to TTL converter lets you connect devices that use RS232 serial ports to devices that only
communicate using transistor-transistor logic (TTL) signals. It’s a convenient and cost-effective solution to
convert RS232 into TTL, so you can connect equipment together based on your devices signal requirements.
Quick and reliable signal conversion
This serial converter is ideal for short distance communication between two devices, and can be used to
connect your computer to microcontroller-based embedded systems and industrial robotics. The reliable
converter easily turns high voltage (-12 to +12V) RS232 signals into low voltage (0 to +5V) TTL signals, and
provides bidirectional data communication at baud rates up to 115.2 Kbps.
Platform independent for easy setup
With a small-footprint design and no software or drivers required, you can easily pair your TTL equipment with
virtually any device that features an RS232 DB9 serial port, such as computers, and industrial control
equipment. Plus, if your host device doesn't feature a native RS232 port, this versatile converter can be coupled
with a USB to RS232 serial adapter (SKU: ICUSB232D - sold separately).
Integrates into mixed environments
The converter delivers dependable performance at extended operating temperatures (-40°C to 85°C), so it
integrates nicely into a variety of workplace settings.
The IC232TTL is backed by a StarTech.com 2-year warranty and free lifetime technical support
