USB 2.0 to RS232 (DB9) converter / adapter with a USB A M / Ż cable 80cm long The DIGITUS USB 2.0 serial adapter is a practical solution for serial connections. The serial RS232 interface is no longer available on newer computer equipment, and the DIGITUS USB 2.0 converter enables data exchange between the USB 2.0 port of the computer and peripheral devices with a serial interface (COM port, RS232), such as weather stations, sensors, control systems machines, STB decoder, game consoles, PDAs, scanners, modems, ISDN adapters and many other peripherals. The USB 2.0 adapter is downward compatible with USB 1.1 and allows you to adjust the transmission speed between 75 bits and 128,000 bits per second. Thanks to the individually configurable FTDI chipset, compatibility with all standard operating systems is ensured, as well as power-management and remote-wake-up. Power is supplied via the USB port, no need for a separate power supply.

The advanced AXAGON ADS-1PQN active USB converter easily extends your computer with a RS 232 standard serial port. The highest level of compatibility between USB - serial RS232 adapters thanks to the use of an original valued chip by the Scottish Company FTDI. The fixed 1.5 m long USB-A cable is suitable for use with both a desktop computer and a laptop. The cable is equipped with gold-plated connectors and contacts, the very durable body of the adapter is also suitable for industrial applications. Double shielding protects transmitted signals from adverse interference. The converter is the ideal accessory for your computer to connect barcode readers, cash register printers, scanners, microcontroller programmers, CNC machines, modems, and to upgrade or configure set-top boxes, security devices, switches, transmitters and other devices.  Input:   USB 480Mbps interface (USB 2.0), backward compatible with USB 1.1. Connecting USB type A male connector located on a fixed 1.5 m cable. Output: 1x serial RS-232 port with a DB9 male connector integrated in the adapters body. Transmission rate adjustable in range 300 bit/s - 250 kbit/s. Compatible with 16C950 UART, backward compatible with 16C550, 16C650, 16C750 and 16C850. Other features: Plug and Play support. FIFO buffer sending 256B and receiving 128B. Adjustable flow control Xon/Xoff, hardware or none. Adjustable word length 7 or 8 bits. Adjustable parity (even, odd, none, mark, space), 1 or 2 stop bits. Adjustable usage of the FIFO Buffer: receiving (64-4096b) and sending (64-4096b). Adjustable latency 1 - 255 ms. Adjustable interrupt 0 10.000 ms (read) / 0 10.000 ms (write). Adjustable idle pause 1 - 3600 seconds. Option to activate other functions: Serial Enumerator, Serial Printer, Cancel If Power Off, Event On Surprise Removal, Set RTS On Close, Disable Modem Ctrl At Startup, Enable Selective Suspend. Adjustable number of the port COM1 to COM256. Adapter power supply via USB (bus power) - no auxiliary power supply required. Gold-plated connectors and contacts ensure reliable connection and prevent oxidation, thus ensuring a long life of the converter. Cable outer diameter 5 mm, double shielded.
