- Convert 2 channels in each direction from 5V TTL (“Transistor Transistor Logic") to RS-232
- Baud rates up to 115.2 kbps
- Powered from RS-232 data/handshake lines - no power supply required
Model 232LPTTL, 4-channel TTL/CMOS converter, makes easy connections between TTL equipment and RS-232 ports and operates at data rates up to 115.2 kbps. It converts two channels (TX and RX) in each direction (bi-directional) from TTL to RS-232. Model 232LPTTL converts RS-232 to 5VDC TTL/CMOS competitive levels. Two channels convert from RS-232 to TTL/CMOS signals and two channels convert from TTL/CMOS signals to RS-232. The converter supports TD, RD, RTS, and CTS. DB9S female connector on the RS-232 side. DB9P male connector on the TTL/CMOS side. The converter is powered from the RS-232 data and handshake lines, whether the lines are high or low. Use this converter with almost any micro-controller or programmable logic controller (PLC) that supports TTL.
