RS-232 to

TTL CONVERTER

User Manual

DA-70162

I. Summary

 Reliable communication between the equipment standard serial interface

 The external equipment or intelligent instrument, conversion to standard serial interface

RS232 to TTL interface converter can be a standard RS232C serial interface data: sending
TXD and a receiving RXD signals into TTL/COMS compatibility level. TTL level is 0-5V, no
external power supply, the internal use of the unique "RS232 charge pump circuit", don't
need to initialize the RS232 serial port can be obtained with zero delay, power supply;
automatic control data flow direction of I/O circuit is unique, and without any handshake
signals (RTS, DTR), so as to ensure the RS232 written in full duplex mode under the
program without change can perform well in TTL mode, to ensure that suitable for the
existing software and hardware interface.
