Null modem cables and adapters connect two serial devices that require a null modem (cross-wired) configuration. This 6-ft. (1.83 m) cable has a DB9 female connector on one end and a DB25 male connector on the other. Superior molded cables with foil-shielding offer maximum EMI/RFI protection. Gold-plated connectors and contacts provide superior conductivity.

Connect a RS232 serial device to the USB port on your computerConnectors: USB-A (M); DB25 (M); DB9 (M)No external power is requiredSupports data transfer rates up to 230 kbpsPremium double-shielded cable with gold-plated contacts, tinned copper braid and an aluminum Mylar foil shield that eliminates cross-talk and reduces EMI/RFI interferenceCompatible with Windows, Mac and Linux computersCompatible with Android tablets / phones with USB Host Mode (OTG) support and OS version 3.2 and above

Connects a Printer, Router or Other DTE Serial Device to Your Computer’s USB-A PortThis 30-inch USB to RS485 adapter cable turns your computer’s USB port into an RS422 or RS485 serial port and avoids the expense of upgrading your reliable serial devices. No external power source is needed. Just connect the cable to your computer and insert the included CD into your computer’s CD drive in order to launch the driver and assign the cable a COM port. It supports USB 2.0 specifications and data transfer speeds up to 230 Kbps, which is almost twice as fast as a built-in serial port. It is backward compatible with USB 1.1 devices. Note: The U209-30N-IND will pull power from the host device. If connected to a USB2.0 host, 0.5A of max power will be provided. If connecting to USB3.0 host, 0.9A of power will be provided. If your device is not working properly, be sure you are connecting to the proper USB port.COM Retention Feature for Convenient Reassigning of COM Values to PortsThe hot-swappable USB to RS422 adapter with built-in FTDI chipset offers COM retention. It automatically reassigns the same COM port values to each port, so when the cable is disconnected or the system is rebooted, no additional configuration is needed. The FTDI USB to serial adapter also supports RS485 auto-transceiver turn around with unique featured ATTA hardware, as well as remote wake-up and power management. A DB9-to-terminal-block adapter is included for making hardwire connections.Double Shielding Protects Your Data from Destructive Line NoiseFoil and braid shielding helps fight against electromagnetic interference and radio frequency interference (EMI/RFI) that impedes your signal and can distort or destroy data. The auto-sensing feature solves DCE/DTE conflicts without the need for cross-wired serial cables or adapters.3-Year WarrantyThe U209-30N-IND is backed by a 3-year warranty, ensuring reliability and performance.
