High Speed USB Serial Adapters Standard serial ports via USB 2.0 without replacing peripheral hardware or application software KEY FEATURES As we continue in the race tobecome the industryleader , our highperformance device 1, 2, 4 or 8 independent serial ports connectivity line expands with the new high RS-232 or software-selectable speed USB2.0 Serial Adapters. The next RS-232/422/485 generation USB Serial Adapter hits speeds of up to 921.6 kbps, 1024-byte FIFO and Compatible with USB 1.1 hardware and software flow control. Plug-and-play capability 2XU USB Serial Adapters enumerate themselves as standard Devices enumerate themselves as Connect serial peripherals with USB COM ports that are compatible with all standard COM ports 2.0 Serial Adapters standard RS-232 or RS-232/422/485 devices and software created for them. Speeds up to 921.6 kbps You can now broaden the range of With the industrial surge suppression external peripherals used on your IND option, you can safeguard the USB High speed UARTs with 1KB FIFOs to computer at higher speed rates than the Serial Adapter. The IND option is ideal boost data rates USB 1.1 series, with the introduction of for implementing USB-to-serial networks the High Speed USB 2.0 Serial in factories, power plants and other Optional surge suppression package Adapters. The USB 2.0 has more potentially harsh industrial (standard on Embedded products) bandwidth that allows higher data rates environments. USB 2.0 is fully on the serial ports for more efficiency. compatible with USB 1.1 devices. The Full modem control and hardware and older devices work with the new bus, software flow control The new High Speed USB Serial and vice versa. Adapter line gives your laptop or Bus powered: no external power required workstation the ability to communicate The 400 Series models introduce the between a USB port and up to eight RS- software-selectable RS-232/422/485 Embedded (board-only) units also 232, RS-422, or RS-485 serial (Multi-Electrical Interface or MEI). The available peripherals. It adds the COM port(s) via MEI capability is available on all ports at its USB connection and is compatible the click of a mouse. LEDs visually tell Windows 2000/XP, Linux support coming with new and legacy RS-232 or RS- you which ports are using which soon 232/422/485 devices. The USB Serial protocol, so go ahead, mix and match. Adapters are the ideal solution for a RoHS compliant variety of industries and applications Embedded USB Serial Adapters for including banking, retail and industrial custom enclosures automation where PCs have a 5 year warranty significantly shorter lifecycle than the If youre looking to seamlessly connect peripherals that use them. multiple serial peripherals via a single USB port in a custom enclosure, try RXU board-level solutions, Embedded USB Serial Adapters.
