The DB9-USB-RS232 modules are designed to directly replace an existing DB9, the industry accepted name for a DE9 connector, RS232 connection with a drop-in USB replacement connection. The modules will replace a male or female DB9 RS232 connector with a USB mini-B connector. The application PCB containing the existing DB9 RS232 connector does not require any modification, only the replacement of the D-type connector with the appropriate DB9-USB-RS232 module. A male DB9 should be replaced by a male DB9-USB-RS232-M and a female DB9 should be replaced by a female DB9-USB-RS232-F. The modules contain all necessary electronics to convert between USB and RS232. The purposes of the modules is to provide a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports by replacing the DB9 connector with this miniaturised module which closely resembles a DB9 connector. The module uses a standard USB-MINI-B connector for connection to an upstream host or hub port.
