Hardware Configuration
Connection to a VN-QUANTUM Processor
The VN-COMMANDER computer communicates with a
VN-QUANTUM via an Ethernet link. This can either be
‘direct’ or ‘indirect’ as shown in Fig.1. Connection to a
single processor can use either method, but multiple
processors must use the indirect method (
i.e. via a hub).
Direct Connection This method uses a single cable is connected between the
computer’s Network port and the VN-QUANTUM (see
Fig.1a). The cable must be a ‘crossover’ (or ‘null modem’)
type; a normal ‘straight-through’ cable will not work.
The computer’s Network port must be capable of
supporting a 100BASE-T connection as required by the
VN-QUANTUM.
Indirect Connection With this method (see Fig.1b) the connection is made via
a hub, switcher or local area network (LAN). Normal
‘straight-through’ type cables must be used;
a ‘crossover’ (or ‘null modem’) cable will not work.
The hub or switcher connected to the VN Processor must
be capable of supporting a 100BASE-T connection as
required by the VN-QUANTUM.
Ethernet Cables Electrosonic recommends that you use only Category 5
shielded (STP) cables. Suitable cables are readily available
from most computer stores.
A 5 metre (16 feet) ‘crossover’ type cable is supplied with
the VN-QUANTUM Processor. This can also be ordered
separately under part number ES5960.
For further details on cable requirements and connector pin-outs, please
refer to the Technical Data section of the VN-QUANTUM User Guide.
