The FT232RL USB to RS485 DSUB 15pin Male Adapter Cable is a USBtoserial converter that provides RS485 connectivity for LongerPump laboratory syringe pumps and other RS485 devices. Built around the FT232RL chipset, this adapter offers a reliable bridge between a computer or controller and RS485 equipment in a compact, easytointegrate package. The DB15 male RS485 connector ensures direct compatibility with devices that use a DB15 RS485 interface, and the 1.8 meter orange cable length gives flexible mounting and routing on benchtops or in cabinet enclosures. Key benefits Enables USBenabled control and data exchange with RS485 devices, including LongerPump syringe pumps. Uses the proven FT232RL USBtoserial chipset for reliable operation and broad driver support. DB15 male RS485 connector provides direct, plugin compatibility with RS485 equipment. Orange 1.8 meter cable offers clear visibility and flexible setup in lab environments. Compact, simple interface that reduces wiring complexity and accelerates integration. Key attributes Chipset: FT232RL Interface: USB to RS485 Connector: DSUB 15 pin male (DB15) Cable length: 1.8 meters Color: Orange Application: Serial communication with RS485 devices, notably LongerPump laboratory syringe pumps Compatibility: Works with FTDI driverenabled systems and RS485 devices Functionality and performance USB to RS485 conversion to enable reliable serial communication between a computer/controller and RS485 devices. FT232RLbased design provides standard USB serial behavior with driver support on multiple operating systems. DB15 male RS485 port offers straightforward connection to RS485 equipment that accepts a DB15 interface. The 1.8 meter cable length provides ample reach for bench setups while maintaining manageable cable routing. Compatibility and use Suitable for use with LongerPump laboratory syringe pumps that require an RS485 connection via a USB host. Compatible with systems that support FTDI USBtoserial drivers (Windows, Linux, macOS environments typically supported through FTDI drivers). Intended for serial communication in laboratory and research settings, enabling easy integration into automation and datalogging workflows. Two to three use cases Use case 1: Connect a LongerPump syringe pump to a computer for setup, calibration, and data logging through USB, using the RS485 link for control and status reporting. Use case 2: Integrate the syringe pump into a small benchtop automation loop by adding other RS485 devices (sensors, controllers) on the same bus via the USB host. Use case 3: a damaged or incompatible USBtoDB15 RS485 cable in an existing lab setup, restoring reliable RS485 communication with minimal downtime. Notes This adapter provides a USBtoRS485 interface using the FT232RL chipset and uses a DB15 male RS485 connector. Ensure your RS485 device accepts a DB15 male connection and is compatible with RS485 signaling. Driver installation and OS compatibility follow the standard FTDI USBtoserial driver process; please install the appropriate FTDI drivers for your operating system if required. Overall, this FT232RL USB to RS485 DSUB 15pin Male Adapter Cable offers a straightforward, reliable solution for connecting LongerPump lab syringe pumps and other RS485 devices to a USBenabled host, with a practical 1.8 meter orange cable for easy setup and identification.
