Analyser

04416001A / Revision 7
WARNING
The RS-485 output terminals are separated from the analyser
mains circuits by reinforced insulation. The terminals must only be
connected to circuits that are themselves separated from mains
voltages by an equivalent isolation method.
CAUTION
To comply with EMC requirements, the RS-485 shall only be connected
using the supplied cable. Refer to section 6.1.1 before making any electrical
connections.
6.2.5 RS-232 port
The analyser can be remotely controlled by a computer using the optional RS-
232 port. The computer is connected to the analyser by the mean of a DB-9 RS-
232C (Null-modem) cable. The computer must have appropriate software to read
the data transmitted by the analyser. See the RS-232 addendum for information
about the analyser communication protocol.
WARNING
The RS-232 output terminals are separated from the analyser
mains circuits by reinforced insulation. The terminals must only be
connected to circuits that are themselves separated from mains
voltages by an isolation method that provides at least this level of
protection.
6.2.6 Auxiliary oven port
The auxiliary oven must be connected to the auxiliary oven port on the rear
panel of the master or secondary chassis. This port is not suitable for third party
ovens.
