passive usb to serial db9 ttl converter details:

 

 

HighTek HU-08 is a universal USB / TTL converter, no external power supply, compatible with USB, TTL standard, the ability to single-ended USB signals into TTL signals, TTL side through the terminal connections. Converter with zero delay automatic transceiver conversion, unique I / O circuit automatically controls the data flow direction, without any handshaking signals (RTS, DTR like), etc. without the jumper settings to achieve TTL mode conversion, plug purposes. Ensure that it meets all existing communications software and interface hardware.

 

HighTek HU-08 interface converter for point to point communications to provide reliable connectivity, data communication speed 300-921600bps, with a power indicator and data traffic lights, supports communication with a USB to TTL conversion.
