Sealevel expands industrial multiport USB hub line
-- Test & Measurement World, 12/11/2007 9:25:00 AM
Sealevel Systems’ USB hub family now includes four-port and seven-port models, which are available in rugged plastic enclosures or in extended-temperature and OEM versions without enclosures, for use in industrial applications.
Both the four-port HUB4P and the seven-port HUB7P are USB 2.0-compliant, providing a full 480-Mbps data rate to the host. They are also backwards-compatible with USB 1.1 and USB 1.0 devices. Each unit includes a wall-mount AC adapter that supplies 500 mA to each attached USB peripheral.
The HUB4P integrates SeaLATCH locking USB ports that are fully compatible with standard USB cables. When used with the supplied SeaLATCH USB host cable, the metal thumbscrew provides a secure metal-to-metal connection to the hub and prevents accidental disconnection of the USB cable. Both the upstream USB type B connector and the four downstream type A connectors can be secured by using SeaLATCH USB cables.
The HUB7P employs seven USB type A connectors and includes a high-retention USB type B connector. Status LEDs indicate external power, connection to the host, and fault conditions. You can also stack the HUB7P with Sealevel’s SeaDAC digital I/O data-acquisition modules.
The HUB4P and HUB7P operate under Windows, Linux, and other USB-aware operating systems without the need for drivers. Prices start at $159.
