Overview

Convert 5-V TTL to RS232 to enable easy connection of many commercial and industrial machines still using TTL as a means of communication.

The RS-232 to TTL Converter enables you to control TTL devices. The converter is fast, too - it supports serial data rates of up to 115 kbps!

Just plug it in and you're ready to go. This tiny converter takes almost no space at all, and you can use it with virtually any microcontroller or programmable logic controller that supports TTL.

It also converts two channels (TX and RX) in each direction from RS-232 to TTL.
