  • USB 2.0 (compatible with USB 1.1)
  • Plug-and-play compatibility
  • Devices enumerate themselves as standard COM ports
  • Speeds up to 921.6 kbps
  • High-speed UARTS with 1KB FIFOs boost data rates
  • Full modem, hardware and software flow control
  • Bus powering – no external power required ESU2-400 QSU2-100 PRODUCT FEATURES Connect and broaden the range of external peripherals on your computer with these USB 2.0 high speed serial adapters. The USB 2.0 standard has more bandwidth allowing higher data rates on serial ports for greater efficiency. USB 2.0 is fully com- patible with USB 1.1 devices. Older devices work with the new bus, and vice versa. These USB serial adapters give your laptop or workstation the ability to com- municate between a USB port and up to eight RS-232, RS-422, or RS-485 serial peripherals. The USB serial adapters enumerate themselves as standard COM ports via the USB connection and are compatible with new and legacy RS-232 or RS- 232/422/485 devices and the software created for them. The adapters support data rates up to 921.6 kbps, 1024-byte FIFO and hardware/software flow control.

400 Series Models feature software-selectable RS-232/422/485 MEI (“Multi-Electri-

cal Interface”). MEI capability is available on all ports at the click of a mouse. LEDs visually tell you which ports are using which protocol – so go ahead, mix and match. These USB serial adapters are the ideal solution for a variety of industries and applications including banking, retail and industrial automation where PCs have a significantly shorter lifecycle than the peripherals that use them.
