Bridge the gap between legacy RS-232 equipment and modern TTL/CMOS devices with the B+B SmartWorx 232LPTTL and 232LPTTL33 powered serial converters. These dual-channel translators are designed for reliability in industrial environments, labs, and embedded development, delivering bidirectional signal conversion between RS-232 and TTL/CMOS levels. With two RS-232-to-TTL/CMOS channels and two TTL/CMOS-to-RS-232 channels, you can connect microcontrollers, sensors, and control systems to legacy serial gear without sacrificing data integrity or performance. The model lineup includes 232LPTTL (5V TTL) and 232LPTTL33 (3.3V TTL) variants, allowing you to choose the voltage level that matches your target device. This is a convenient, plug-and-play solution for engineers, technicians, and makers who need dependable serial interfacing in a compact, powered converter package.

  • Bidirectional two-channel translation: RS-232 signals are converted to TTL/CMOS levels on two channels, while two channels translate TTL/CMOS signals back to RS-232, enabling seamless two-way communication between devices with different logic levels.
  • Two model variants for TTL voltage compatibility: Choose the 232LPTTL model for 5V TTL/CMOS logic or the 232LPTTL33 model for 3.3V TTL/CMOS logic, ensuring compatibility with your host system without level-shifting headaches.
  • DB9 connectors for easy wiring: The design features a DB9 female RS-232 port and a DB9 male TTL/CMOS port, enabling straightforward, shielded connections to a wide range of equipment and development boards.
  • Powered operation for reliable performance: This is a powered converter that relies on an external supply to maintain stable voltage levels and robust signaling across all channels, even with longer cable runs.
  • Versatile, plug-and-play utility: Ideal for industrial automation, test benches, instrumentation, and embedded projects where RS-232 devices must interface with modern microcontrollers or SBCs without software drivers or complex configuration.

Technical Details of B+B SmartWorx Serial RS-232 DB9 Female To TTL DB9 Male Port Powered Converter

  • Models and voltage options: 232LPTTL (RS-232 to 5V TTL/CMOS levels) and 232LPTTL33 (RS-232 to 3.3V TTL/CMOS levels). These two variants provide the TTL logic compatibility required by different host devices.
  • Channel configuration: Two channels are dedicated to converting RS-232 signals to TTL/CMOS levels, and two channels are allocated for converting TTL/CMOS signals to RS-232, enabling bidirectional data flow in each direction.
  • Connectors and ports: DB9 female connector on the RS-232 side and a DB9 male connector on the TTL/CMOS side facilitate convenient pairing with standard equipment and development boards.
  • Power and operation: This is a powered converter designed to maintain stable signaling. It requires an appropriate external power supply compatible with the chosen model (5V for 232LPTTL or 3.3V for 232LPTTL33).
  • Compatibility and use cases: Ideal for bridging legacy serial devices with modern controllers, microcontrollers, or USB-to-serial adapters, in settings such as manufacturing test stations, automation panels, and research labs.
  • Data integrity: Built to preserve data integrity across level shifting boundaries, supporting typical RS-232 communication schemes and asynchronous serial data exchanges common in industrial and development environments.
  • Physical footprint and integration: Designed for compact integration into control cabinets, test fixtures, or desk-side setups where space is at a premium but dependable serial interfacing is required.

how to install B+B SmartWorx Serial RS-232 DB9 Female To TTL DB9 Male Port Powered Converter

  • Power the converter with the appropriate supply for your model (5V for 232LPTTL or 3.3V for 232LPTTL33). Ensure the power source is stable and within the specified voltage range.
  • Connect the RS-232 device (such as a PC, terminal, or instrument) to the RS-232 DB9 female port on the converter using a standard DB9 serial cable.
  • Connect your TTL/CMOS device (such as a microcontroller, FPGA board, or interface module) to the TTL/CMOS DB9 male port on the converter using the corresponding DB9 cable.
  • Configure the communication parameters on both sides to match (baud rate, data bits, parity, and stop bits). Consistent settings are essential for reliable data transmission across the converter.
  • Power up both devices and perform a basic test, such as sending a short data string from the TTL/CMOS side and verifying reception on the RS-232 side (or vice versa) using a terminal program or simple loopback test.
  • In noisy environments or long cable runs, consider proper cable shielding and grounding practices to minimize interference and ensure stable performance.

Frequently asked questions

  • Q: What voltage levels does this converter support?
  • A: The 232LPTTL model uses 5V TTL/CMOS levels, while the 232LPTTL33 uses 3.3V TTL/CMOS levels. Both variants provide bidirectional conversion between RS-232 and TTL/CMOS signals.
  • Q: Do I need drivers to use this converter?
  • A: No additional software drivers are required. The device uses built-in level-shifting circuitry, so it can be used with standard serial software or terminal programs once the host parameters are configured correctly.
  • Q: How many channels are supported and what directions do they support?
  • A: The converter supports four channels in total: two RS-232-to-TTL/CMOS channels and two TTL/CMOS-to-RS-232 channels, enabling bidirectional communication in both directions for each channel pair.
  • Q: Which connectors are used?
  • A: The device uses a DB9 female connector for the RS-232 side and a DB9 male connector for the TTL/CMOS side, aligning with common serial interface conventions for ease of wiring.
  • Q: Which scenarios are ideal for this converter?
  • A: It is well suited for bridging legacy RS-232 devices with modern microcontrollers, embedded development boards, instrumentation, and factory test setups where reliable, level-mapped serial communication is required without modifying existing hardware.
  • Q: How should I power and ground the device?
  • A: Use a stable external power supply matched to your model (5V or 3.3V). Ensure proper grounding of the RS-232 side and the TTL/CMOS side to minimize noise and ensure clean data transmission.

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review! My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.

So cute
Size: Large, Color: Pumpkin
My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. They are a bit heavy and awkward for my dogs to hold onto but they do like them.

Cute toy and super tough!
Size: Small, Color: Lobster
My small dog is a serious chewer, and this lobster toy has been holding up great. Usually, he destroys toys within a day, but this one’s still going strong after a couple of weeks. The shape is perfect — easy for him to grab and chew, and the little claws keep him entertained. The filet mignon flavor must be good because he goes right for it every time. It’s sturdy without being too hard on his teeth, and it doesn’t leave any mess or pieces behind. If you’ve got a small but mighty chewer, this one’s definitely worth it. Cute design, lasts forever, and keeps my pup busy — total win. 🦞🐾
