| US Digital announces SEI-USB interface device | ||
|
||
 The SEI-USB is an interface device that connects US Digital’s SEI compatible devices to a standard USB 1.1/2.0 port. SEI (Serial Encoder Interface) bus is a simple, quick and convenient network that connects up to 15 addressable SEI devices. The SEI-USB will supply power form the USB port to a limited number of SEI devices on the bus. The SEI-USB limits the power to the maximum design spec of the USB port. A red LED will be lit when additional power is required and the PS-12 power supply should then be used. For applications requiring a large number of SEI devices which exceed the SEI-USB power rating, an external 12 VDC power supply can be connected to the SEI-USB’s power port. The SEI bus uses two RS-485-like differential pairs, one for “busy” flow control, and the other for bi-directional serial data. Features: |
