## Description

Overview This is an industrial USB to RS232/485/TTL isolated converter with original FT232RL inside. It features embedded protection circuits such as power insulation. ADI magnetical isolation, and TVS diode, etc. What's more, the USB TO RS232/485/TTL comes with an aluminum alloy enclosure, make it solid and durable to work. The USB TO RS232/485/TTL is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, It is an ideal choice for industrial control equipments and/or applications with high communication requirement. Features Adopt original FT232RL, fast communicating, stable and reliable, better compatibility Onboard unibody power supply insulation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody magnetical insulation, allows signal insulation, high reliability, strong anti-interference, low power consumption. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance. Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stable, without interfering each other Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process opening, solid and durable. 3 LEDs for indicating the power and transceiver status.

## Questions & Answers

**Q: Do i have to use the 232 port ot does the usb connection map as a com port?**
A: You do not have to use the RS232 port, I use one of these to work RS485 over a BacNet MS/TP network to find my devices.  The USB does setup as a com port and is powered from the USB port, the device works flawlessly for what I need it for.  For the price, it is well worth it as I use many protocols over the RS485 for device discovery.

I am currently looking for a WiFi version of this or a type like this, I work building automation and devices like this make my job much easier.

**Q: What type is product, echo or non-echo ? the echo is the reflection of transmitting data on the receiving line.**
A: Dear cuetomer, it's non-echo, if there is any other question for our products, please feel free to contact us. Thank you.

**Q: Does this work with the modbus protocol?**
A: Yes, it will work for whatever RS232/RS485/RS422 protocol you decide to use.

**Q: Can i convert from rs232 to ttl?**
A: Hi, Sorry,it can't convert from rs232 to ttl.
It can only support USB TO RS232, USB TO RS485, USB TO TTL (UART), not support RS232 to TTL.
And it can't support USB to convert to RS232, RS485 and TTL at the same time.
And RS232, RS485 and TTL cannot be converted mutually. It only support USB to RS232, RS485 or TTL.

*by C***! on 4 June 2024*

I ordered this because my previous usb to "rs232" cable didn't actually have true rs-232 voltage levels, I needed it in order to program a curtis golf-cart motor controller... As soon as I plugged in this Waveshare box, worked instantly! Windows 10 found the driver on it's own, and within mere minutes of unboxing; I was in business programming a motor controller for a local guy who had a broken down mobility scooter. The box housing seems really high quality I feel, and its heavy too which I like about it. A+ Waveshare!
