TLC485 change TD and RD RS-232 lines to RS-485 signals. All are port powered and feature Automatic Send Data Control. SDC automatically enables the RS-485 driver when data is present on the RS-232 side. Control of the driver is automatic at rates up to 115.2 kbps.It is used widely in the field of electricity, industrial automatic control, IC card billing system. It is a high quality, economical data interface conversion product.
Features
1. Plug and play, small volume, easy to installation
2.Convert RS-232 data transmit (TXD) and data receive (RXD) signal into balance half duplex RS-485 signals.
3. Powered from RS-232 handshake lines — no power supply needed!
4.Point to multiple point
5. Automatic Send Data Control - no software drivers needed!
6. Auto sense serial signal rate, zero delay automatic transmit
