UTEK UT-2201 Port-powered, RS-232 to - Review

When it comes to connecting different devices, one of the most common hurdles is the task of bridging communication protocols. In most cases, devices are built to communicate using different protocols, which may not necessarily be compatible with each other. This is where data converters come in handy. One such device is the UTEK UT-2201, a port-powered RS232 to RS485/422 converter from UOTEK. In this review, we’ll explore the features of this device and its capabilities for solving communication problems.

Firstly, let’s look at the physical characteristics of the UTEK UT-2201. The converter comes in a mini-size package that measures 63mmX33mmX17mm, making it easy to deploy in any location. The device is designed to connect any RS485 device directly to a COM port. The connector consists of a male DB9 for RS-485 and a female DB9 for RS-232, complete with a terminal block. This versatile design means that you can easily connect to different types of devices with varying communication protocols, without worrying about compatibility issues.

One key feature of the UTEK UT-2201 is its support for asynchronous half-duplex differential transmission. This means that the device can send data in both directions, but only one direction at a time. The transmission mode is differential, which helps reduce signal interference and, in turn, improves data transmission rates. The device operates at a range of baud rates, ranging from 300bps up to 115.2Kbps, which makes it perfect for high-speed data transmission applications. Additionally, the device supports transmission via twisted-pair or shielded cable, which gives you more options when it comes to cabling.

Another noteworthy feature of the UTEK UT-2201 is its transmission distance. When using RS-485 mode, the device can transmit data up to a distance of 1,200 meters. This is a significant distance that makes the device ideal for applications that require long-distance data transmission, such as smart factories, industrial automation, and security systems. In RS-232 mode, the device can transmit data up to a distance of 5 meters, which is sufficient for most applications.

When it comes to environmental conditions, the UTEK UT-2201 performs well in temperature and humidity extremes. The device can operate in temperatures ranging from -25℃ to 70℃ and relative humidity levels between 5% to 95%. This makes the device suitable for deployment in harsh environments, such as outdoor industrial applications.

From a user perspective, the UTEK UT-2201 is easy to set up and operate. The device is powered by the RS-232 port, which means you don't have to worry about external power supplies. The device is also plug-and-play, which means it doesn't require any special drivers. Simply connect the device to the RS-232 and RS-485/422 devices, and you are good to go.

As for its downsides, the UTEK UT-2201 has some drawbacks. The device does not provide galvanic isolation, which means that there could be instances of ground loop currents that may affect the quality of the signal being transmitted. This is especially true when the RS-232 and RS-485/422 devices are powered by different sources. Additionally, the lack of surge protection means that the device may be susceptible to electrical spikes and surges.

In summary, the UTEK UT-2201 is a reliable and versatile data converter that helps users bridge communication protocols between RS-232 and RS-485/422 devices. Its compact size, high data transmission rates, and long-distance capabilities make it ideal for industrial applications requiring long-distance data transmission. The device performs well in temperature and humidity extremes, making it suitable for deployment in harsh environments. However, its lack of galvanic isolation and surge protection are notable limitations that need to be considered when deploying the device. Overall, the UTEK UT-2201 is a solid choice for users looking for a reliable and effective data converter solution.
