This section is intended for for qualified technicians involved in installing
EVE/NET systems. The information it contains is not required in order to
understand the operation or use of the system.
Installation
The EVE/NET system is derived from a well-proven networking system designed for industrial
use, with over ten million systems installed. As a result it is very rugged and tolerant of faults and
poor configuration. Notwithstanding the above, the configuration and subsequent successful
operation of an EVE/NET system is assisted by understanding the following parameters.
1. Range Settings
2. Cabling
3. Termination
4. Power
5. Grounding
Range Settings
Each EVE/NET peripheral has a range setting that governs both the maximum cable length and
the communication speed. These are: 50 ft (fastest) and 1200 ft (slowest). The default and
recommended setting is 300 ft. At slower range settings, the screen update time will be more
noticeable, at faster range settings, correct cabling and configuration is more important. Note that
the maximum distance is governed more by the speed of light than by the cable quality, so the
maximum length for a given setting should not be exceeded. All systems connected by the same
cable must have the same range setting. Non-communication, permanent off-line indications or
frequent error reports may be a sign of incorrect range settings.
Cabling
There are two issues to consider when cabling an EVE/NET network:
i. Topology - this is the way the EVE/NET nodes are connected. (A node is either a remote
console or an EVE/NET equipped effects processor.) The nodes must be connected in a
“daisy-chain” pattern, so that the cable goes from A to B to C to D etc. They may not be
connected in a “star” pattern, where the cable goes from A to B and A to C and A to D,
etc.
ii. Cable Type - EVE/NET requires eight way RJ-45 type cabling and connectors. All eight
pins must be connected to the same numbered pins on each connector. Telephone-type
T-adaptors may be used as long as the common plug is connected directly to the EVE/NET
socket.
For short runs or temporary hookups, RJ-45 type telephone leads can be used. For long
runs, especially when the total length approaches the “range” limit (see below), CAT-5
