This converter provides two way RS232 serial communications signal conversion between the TTL (Transistor Transistor Logic) output (from an OOPic or other PIC) to and from a personal computer RS232 serial COM port.  This converter can be used on any Micro controller/PIC which has TTL serial communications that needs to be converted to RS232.

These cables are 5V TTL signal converters.  The cable converts 0v & 5v nominal TTL signal to �12v & 12v RS232 serial signal.  We also have 3.3V TTL signal converters too.  These cables require 5V power from the TTL side to operate.

The RS232 serial cable with voltage level converter comes completely assembled.  The circuitry is built into the cable. 

For further details, downloads, and instructions see our RS232 page.

The RS232 to TTL level converter serial cable is available in two cable lengths and multiple connector configurations. 

We sell different Types of Cables/Connectors. This is a type 3 connector that has handshaking capabilities

 Type 3: This is our Handshaking cable.   It has the type 1 connector for the Tx and Rx and a 2-pin connector for RTS and CTS Handshaking.  For the mating 4-Pin Friction Lock Header follow this link.
