Port Powered rs232 to rs485 converter circuit, industrial rs485
converters with RS-232 side DB-9 female Plug and play, small volume, easy to installation
Bi-directional convert RS232 into RS485
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.
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
