 The DSP7x4 is designed to provide real time parameter display
or numeric information in a 1-Wire network. The DSP7x4 provides four,
4-inch digits, a decimal point, a colon and a degree mark. The display background
is flat black for high contrast and the LEDs are among the brightest available.
This combination results in a super clear display at distances of up to 50 feet.
At distances of up to 20 feet the DSP7x4 is visible in direct sunlight. Multiple
units can be cascaded to produce seamless numeric displays of variable length.
The DSP7x4 may be placed up to 2000+ feet from the host using CAT-5 twisted pair
cable in a network of up to 200 1-Wire devices. In addition all I/O and data communications
are CRC16 error checked for accuracy. The DSP7x4 has a built-in multidrop controller
which provides a unique 64 bit registration number (8-bit family code + 48 bit serial
number + 8 bit CRC) assuring error-free selection and absolute identity; no two
parts are alike. Unique addressing allows sensor function to be identified absolutely.
The DSP7x4 requires a 1-Wire host interface or adapter such as the EDS HA2, HA3,
HA4, HA5, HA7S, and HA7T; or Dallas Semiconductor DS9097U, DS9097E.
Because OneSix DDE Server directly supports all EDS 1-Wire products and handles
all the communications with the DSP7x4 display, you do not have to be a programmer
to use this product. Any Windows application that can use DDE can talk to the DSP7x4
4-character LED display. Examples of such applications include Microsoft Office
products like Word & Excel, Wonderware Intouch, National Instruments LabView & LookOut,
Capital Equipment Corp. TestPoint, and if you are a programmer development applications
like Microsoft Visual Basic and Borland Delphi.
