IFC-W1R-TTL-RS232-01-000: Line Interface (TTL to RS-232)
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 micro controller circuits which currently do not have RS-232 level interface. The TTL to RS-232 Interface derives its power from the micro controller board. Connections include: Transmit Data (TXD); Receive Data (RXD); Request to Send (RTS); and Clear to Send (CTS).
Applications
- Construction Equipment, Mobile Equipment, Material Transport Vehicles, On-road Vehicles (Bus)
