Forensic and criminal investigation: Forensic Equipment Forensic equipment are powerful tools specially designed for use in criminal investigations to store and duplicate crime data and evidence. It uses read-only technology to prevent data from being overwritten. 3.5/2.5 ATA and Serial ATA mobile racks, PCMCIA hard drives, MicroDrives, and Type I/II compact flashes are ideal storage devices for use with forensic equipment. USB-122S (Horizontal Type) WRITE PROTECTED FORENSIC USB 2.0 to EIDE bridge board featuring Acer Laboratories Inc. M5621 (High-Speed USB 2.0 to ATA/ATAPI Native Bridge Controller) The USB-122S implements a bridge between one USB 2.0 port and one ATA or ATAPI based mass storage device port. This bridge adheres to the Mass Storage Class Bulk-Only Transport specification and is intended for self-powered devices. Hardware design allows CBW command queuing, which allows data transfer rates of up to the USB theoretical maximum. The USB port of the USB-122S is connected to a host computer directly or via the downstream port of a USB hub. Host software issues commands and data to the USB-122S and receives status and data from the USB-122S using standard USB protocol. Built-in USB2.0-to-IDE Interface Controller with general IDE interface & bulk-only transport of USB mass storage class support industry-standard 8/16-bit PIO/DMA & Multi-word DMA and Ultra Mode DMA modes 0-4 (upto UDMA66) for storage devices as DVD/CD-ROM, CD-R/W and Harddisk device, etc. The ATA/ATAPI interface supports The device initialization process is configurable, enabling the USB-122S to initialize most ATA/ATAPI devices without software intervention. FEATURES Complies with the USB-IF specifications for USB 2.0, the USB Mass Storage Class, and the USB Mass Storage Class Bulk-Only Transport Operates at High (480Mbps) or Full (12Mbps) speed Uses one external serial EEPROM containing the USB device serial number, vendor and product identification data, and device configuration data Self Powered Mode Of Operation Built-in High-performance Micro-controller Engine for interface, flow & multi-functional control Support for ATA/ATAPI devices configured either as master or slave ATA/ATAPI Interface Supports: - PIO Mode 0 ~ 4 - Multiword DMA Mode 0 ~ 2 - Ultra DMA Mode 0 ~ 4 - Supports 48-bit addressing for large hard drives (>128GB). Provide High Speed LED and Device Access LED Operating System Support: Windows 98 SE/ Me/ 2000/ XP; MacOS 8.6 or later IDE (ATA/ATAPI) Interface: There are three types of USB-122S-- USB-122S-M (With IDC 2X20 Male Connector) USB-122S-C (With IDC 2X20 Flat Cable) USB 2.0 Interface: One External USB B-type-4pin Connector DC Power Input Connector: mini 4-pin FDD like Power Connector DC Power Input: DC 5V/ 300mA Physical Dimensions: 2.97" x 1.34" (7.54cm x 3.40cm) Fit to most standard SCSI Enclosure (SCSI I 50pin Connector Form Factor) BENEFITS Enables quick penetration of USB 2.0 markets Complete backward compatibility Leverages ATA/ATAPI peripheral economies of scale Supports both ATA and ATAPI devices by using the same firmware. Support two IDE Devices (Master and Slave). 48-bits LBA addressing (>128GB) support. Allows use of existing peripheral software applications Provides cost-effective solution for remote location of peripheral devices User friendly interface - Plug&Play and Ease of use Enables hot swappable peripherals
