Features

4-channel conversion between 3.3 Vdc TTL/CMOS and RS232. TD, RD, RTS, CTS support. Powered by pin/signals 7(RTS), 4 (DTR), 3(TD); lines can be high or low, but must be present to power the converter. Pin 5 is SG for both connectors. Use with microcontrollers or PLCs supporting TTL.

• Converts 2 channels in each direction from RS-232 to 3.3 V TTL/CMOS
• Data rate: up to 115.2 kbps baud
• Powered from RS-232 data/handshake lines (high or low) - no power supply needed
• RS-232 DB9 female connector; TTL/CMOS DB9 male connector
