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 tobecomethe industryleader,ourhighperformancedevice 1, 2, 4 or 8 independent serial ports connectivitylineexpands with the new high speed USB2.0 Serial Adapters. The next generation USB Serial Adapter hits speeds of up to 921.6 kbps, 1024-byte FIFO and hardware and software flow control. Connect serial peripherals with USB 2.0 Serial Adapters You can now broaden the range of external peripherals used on your computer at higher speed rates than the USB 1.1 series, with the introduction of the High Speed USB 2.0 Serial Adapters. The USB 2.0 has more bandwidth that allows higher data rates on the serial ports for more efficiency. The new High Speed USB Serial Adapter line gives your laptop or workstation the ability to communicate between a USB port and up to eight RS232, RS-422, or RS-485 serial peripherals. It adds the COM port(s) via its USB connection and is compatible with new and legacy RS-232 or RS232/422/485 devices. The 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. Rev 1.0, 08.22.06 2XU USB Serial Adapters enumerate themselves as standard COM ports that are compatible with all standard RS-232 or RS-232/422/485 devices and software created for them. With the industrial surge suppression “IND” option, you can safeguard the USB Serial Adapter. The “IND” option is ideal for implementing USB-to-serial networks in factories, power plants and other potentially harsh industrial environments. USB 2.0 is fully compatible with USB 1.1 devices. The older devices work with the new bus, and vice versa. RS-232 or software-selectable RS-232/422/485 Compatible with USB 1.1 Plug-and-play capability Devices enumerate themselves as standard COM ports Speeds up to 921.6 kbps High speed UARTs with 1KB FIFOs to boost data rates Optional surge suppression package (standard on Embedded products) Full modem control and hardware and software flow control Bus powered: no external power required The 400 Series models introduce the software-selectable RS-232/422/485 (Multi-Electrical Interface or MEI). The 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. Embedded USB Serial Adapters for custom enclosures Embedded (board-only) units also available Windows 2000/XP, Linux support coming soon RoHS compliant 5 year warranty If you’re looking to seamlessly connect multiple serial peripherals via a single USB port in a custom enclosure, try RXU board-level solutions, Embedded USB Serial Adapters. HIGH SPEED USB SERIAL ADAPTER SPECIFICATIONS (VERSION 2.0) Ordering Information USB Ports Required SSU: 1 DSU: 1 QSU: 1 Model Ports SSU2-100 1 RS-232 with cable DSU2-100 2 RS-232 with cable DSU2-400 2 RS-232/422/485 with cable QSU2-100 4 RS-232 with cable QSU2-400 4 RS-232/422/485 with cable ESU2-100 8 RS-232 with cable ESU2-400 8 RS-232/422/485 with cable UARTS 1024-byte FIFOs for transmit and receive IND Option: Surge suppression applied to each line that is capable of sustaining up to 40A peak, 8 x 20ìs transient surges, a clamping voltage of 30V and a peak energy dissipation of 0.1 Joules.
