network grade cable should be used. This should be wired to the same standards as a 10
MB/s Ethernet system.
Ü See Appendix A for pin connections, color codes etc.
NOTE (1): An EVE/NET system must not be connected to any other networking system,
as damage and incorrect operation may result.
NOTE (2): When using manufactured leads, be sure to check that the connections are not
reversed (as in a “cross-over” cable). Hold the two ends side by side, facing the same way,
and confirm that the color order of the wires is the same.
Termination
The first and last nodes on the “daisy-chain” must have termination resistors connected. All others
must have termination resistors disconnected. This is done by installing or removing jumpers on
the printed circuit boards (see Appendix C for details). As delivered, the default setting is for
termination to be applied on all nodes - this will have to be changed for systems using more than
two nodes. The EVE/NET system will usually tolerate some redundant or missing termination,
but the rule should be followed for permanent installations and greatest reliability.
Power
Since the remote consoles have their power supplied down the EVE/NET cable, this requires
some consideration. A single Orville can power a single remote console, while a DSP7000/7500
requires an external power supply. (Note that early Orvilles, identifiable by having only two
transformer mounting holes on the right hand side panel rather than the three on later systems,
also require an external power supply.) Allowing multiple Orvilles to power the same line in effect
connects their power supply outputs in parallel, and can cause overheating or other damage.
Thus a simple system involving a single Orville and a single console may use just the supplied
RJ45 cable and default jumpering.
A more complex configuration must be designed rather than just hooked up.
Power supplied from an Orville may be disconnected by removing the 1A fuse near the RJ45
socket.
Eventide can supply a small power adaptor that is capable of powering two remote consoles, and
has useful power and termination options. This is provided as part of the DSP7x00 Installation Kit
and is also available separately.
Ü See the sample layouts in Appendix C for examples.
