Operating the Instrument on the Network
After the network support has been installed, it is possible to exchange data between the instrument and
other computers and to use printers in the network.
A prerequisite to network operation is having the appropriate access rights for the required network
resources. Resources may be file directories of other computers or also central printers.
Access rights can be obtained from the network or server administrator. In that respect it is necessary to
obtain the network name of the resource as well as the corresponding access rights.
To prevent misuse, the resources are protected by passwords. Normally, every entitled user of the
resources is assigned a user name that is also protected by a password. Resources can then be
assigned to this user. It is possible to determine the type of data access, i.e. whether data can only be
read or also written, as well as shared data access. Depending on the network operating system,
different types of usage are possible.
NOVELL Networks
The operating system NETWARE from NOVELL is a server-based system. Data cannot be exchanged
between individual workstations; data transfer takes place between the PC and a server. This server
provides memory space and the connection to network printers. On a server, data is organized in
directories as under DOS and mapped to the workstation as virtual drives. A virtual drive behaves like
an additional hard disk on the workstation, and the data can be edited accordingly. Network printers can
also be addressed like normal printers.
There are two versions of the NOVELL network operating system: bindary-based (NETWARE 3) and
NDS-based (more recent versions of NETWARE). With the older version (NETWARE 3), each server
manages its resources on its own and is independent. A user must be managed on each server
separately. In the case of NDS-based versions, all resources in the network are managed together in
the NDS (NOVELL DIRECTORY SERVICE). The user must log into the network only once and is given
access to the resources according to his/her access rights. The individual resources and users are
managed as objects in a hierarchical tree (NDS TREE). The position of the object in the tree is referred
to as "CONTEXT" with NETWARE and must be known for access to the resources.
MICROSOFT Network
In case of a MICROSOFT network, data can be exchanged both between workstations (peer to peer)
and between workstations and servers. The latter can supply access to files and connection to the
printers. On a server, data is organized in directories as under DOS and mapped to the workstation as
virtual drives. A virtual drive behaves like an additional hard disk on the workstation, and the data can be
edited accordingly. Network printers can also be addressed like normal printers. A connection is
possible to DOS, WINDOWS FOR WORKGROUPS, WINDOWS95/98/ME, WINDOWS NT/XP.
