6.2 CONNECTION DETAILS
The connection to the recorder is terminated at the RJ45 connector located as shown in fi gures 2.1a , and 2.1b ).
The other end of the cable may be terminated, for example, at a hub, a dial-up router or a PC, and it is up
to the user to obtain a suitable cable (normally available from a computer supplier or electronic component
distributor.)
Note: For direct connection between a PC and the recorder, a crossover cable is required. For
all other connections, a ‘straight-through’ connection is required.
6.2.1 Direct PC connection
The RJ45 connector at the rear of the recorder is connected via a crossover cable to the PC network card connector.
6.2.2 PC To remote recorder
As shown in fi gure 6.2.2, one or more recorders’ Ethernet connector can be connected to a Dial Up Router,
plugged into a telephone socket The PC must similarly be connected to a telephone socket via a modem
(shown externally in the fi gure, but often built-in with modern computers.)
The dial-up router (available from computer suppliers etc.) has an associated telephone number, and can also
have a security password system. Both the telephone number and any password(s) must be known to the PC
user before any attempt at communication is made.
The PC can be set up to dial the number automatically, or the number may be dialled manually. Reference
should be made to the computer documentation or help pages if necessary.
Once communication has been established, the software can be run.

6.2.3 Networked systems
For PCs and recorders connected into an internal network, it is necessary only to obtain an IP address (or
name) and the required passwords in order to establish connections between the PC(s) and the recorder(s).
For PCs remote from a networked system which is permanently connected to the internet, it is necessary to
obtain an IP address (or name) and the required passwords in order to establish connections between the PC
and the recorder(s). In many cases it is also necessary that the internal network and ‘ fi rewall’ (if such exists) be
con fi gured to allow access.
For PCs remote from a networked system which is not connected to the internet, a system similar to that
shown in fi gure 6.2.2 is needed.
