RS485 to RS232 Converter with EIA / TIA Standard for Card Access Control Systems
Advantage
1. three kinds of indicators light the data traffic communication situation in time, support the transformation of RS-232 to RS-485.
2. the internal ciucuitry of converter can automatically sense the direction of data flow and enable to control itself by automatic switching.
3.RS-232 interface is connected to the computer by a DB9 female connector; the connection of RS-485 is through a DB9 connector or by the six terminals
4.Widely used in industrial automation control systems, card access control systems, leave without pay parking lot systems,
Automated banking systems, bus fare system, , attendance management systems, highway toll station systems, etc.
