This FT232RL based USB to DSUB 15pin female adapter provides a USB serial interface for devices using a 15pin Dsub connector. Built around the FT232RL USBtoserial IC, it delivers reliable USB connectivity for RS232 and RS485 serial communications. Designed for Cavro XCalibur pumps, the unit features a 3 metre RS485 capable cable with a DB15 female connector, enabling convenient remote mounting and flexible installation. Key benefits USB to serial conversion using the proven FT232RL chipset for reliable data transmission between a USB host and serial devices. Supports RS232 and RS485 serial signaling, enabling compatibility with a range of equipment that uses a DB15 interface. 3 metre cable length provides flexible placement options and reduced cable tension between equipment and the host. DB15 female connector directly mates with standard 15pin Dsub devices, including Cavro XCalibur pump interfaces. Tailored for Cavro XCalibur pumps, helping to integrate these pumps into USBbased control and monitoring setups. Key attributes Chipset: FT232RL USBtoserial IC Interface: USB to DSUB 15pin (DB15) female Serial signaling: RS232/RS485 capable (RS485 signal configuration noted in product title) Cable length: 3 metres Application: Suitable for use with Cavro XCalibur pumps and other devices with a 15pin Dsub serial port Compatibility and usage Intended for Cavro XCalibur pumps and similar equipment that use a DB15 serial interface. Connect a USB host to a device via the DB15 connector using the USBtoserial conversion provided by the FT232RL chipset. Use in RS485 serial communication setups that require a 3 metre connection distance. Use cases Connect a Cavro XCalibur pump to a USBenabled computer for control, configuration, and data logging through the RS485 serial interface. Extend serial communications in a lab setup by linking a USB host to RS485 devices with a DB15 port, using the 3 metre cable for convenient placement. a damaged or missing RS485 serial cable in Cavro XCalibur oriented systems, restoring reliable USBtoserial connectivity over a longer reach.
