Featuring DB9 connectors and a unique charge pump design, it requires no external power and supports a wide operating temperature range, making it ideal for integrating legacy serial devices with modern TTL/COMS systems. ## Description In order to facilitate data communication between external devices or intelligent instruments equipped with different standard serial interfaces, it is necessary to convert the standard serial interfaces. UT-210T interface converter can convert the RS-232C serial interface data transmission (TXD) and data reception (RXD) signals into TTL/COMS compatible level, and the converted TTL level is 0-3.3V, No external power supply is required. Driven by a unique "RS-232 charge pump", power can be obtained without initializing the RS-232 serial port. It has zero-delay automatic sending and receiving conversion inside, and the unique I/O circuit automatically controls the data flow direction. Without any handshaking signals (such as RTS, DTR, etc.), it ensures that programs written in RS-232 in full-duplex mode can run in TTL mode without modification, ensuring that it is suitable for existing operating software and interface hardware. Converter transmission rate 300-115.2Kbps. ## Features - Interface characteristics: The interface is compatible with RS-232C and TTL/COMS standards of EIA/TIA l Electrical interface: RS-232 terminal DB9 female connector, TTL terminal DB9 pin connector. - Working mode: asynchronous full duplex l Transmission medium: twisted pair or shielded wire - Transmission rate: 300BPS-115.2KBPS l Dimensions: 63mm*33mm*17mm - Operating environment: -25Β°C to 70Β°C, relative humidity 5% to 95% - Transmission distance: 5m ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00GI9GPTC | | Best Sellers Rank | #510 in Serial Adapters | | Brand | UOTEK | | Color | Black | | Connector Type | db9 | | Customer Reviews | 4.2 4.2 out of 5 stars (4) | | Input Voltage | 3.3 volts | | Item Dimensions | 6.5 x 4.4 x 2.2 inches | | Item Weight | 1.6 ounces | | Manufacturer | UTEK | | Mfr Part Number | 1 | | Model Number | UT-210T | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | personal | | UPC | 799418887173 | | Unit Count | 1 Count | ## Product Details - **Brand:** UOTEK - **Color:** Black - **Connector Type:** db9 - **Item dimensions L x W x H:** 6.5 x 4.4 x 2.2 inches - **Specific Uses For Product:** personal ## Images ![Utek Ut-210t Rs-232 to TTL Interface Protocol Converters(TTL Output 3.3v Port-Powered, Rs-232 to TTL, Mini-Size - Image 1](https://m.media-amazon.com/images/I/51aYO+mxkML.jpg) ## Questions & Answers **Q: I connected Tx Rx and ground.
