IFC-W1R-TTL-RS232-01-000
Description:
The IFC-W1R-TTL-RS232-01 is an interface which converts communication signals between the TTL and RS-232 signal levels. This interface is ideal for providing RS-232 communication capabilities for microcontroller circuits which currently do not have RS-232 level interface. The TTL to RS-232 Interface derives its power from the microcontroller board. Connections include: Transmit Data (TXD); Receive Data (RXD); Request to Send (RTS); and Clear to Send (CTS).
