Digital Signal Processing board, DSP-6x
Purpose and description
The DSP-6X is a general-purpose data acquisition, control and
signal processing microcomputer board. It is targeted for high
performance echo sounder applications. The board is remote
controlled by a host via Ethernet under the TCP/IP/UDP
protocol.
The DSP-6X is based on a signal processing microcomputer
from Analog Devices named ADSP-21062, also known as the
SHARC (Super Harvard Architecture Computer).
How it works
There are two Ethernet interfaces on the board. Both the DB-15
AUI connector and the RJ-45 UTP plug is accessed at the front
of the board. The DSP-6X communicate with an external host
via the TCP/IP/UDP Protocol.

LEDs
On the front panel of DSP-6X there are 4 LED indicators:
TX: Flashes when data is transmitted via Ethernet.
RX: Flashes when data is received via Ethernet (even if the data
is not for my Ethernet address).
