WARNING!

WhenconnectingacommunicationconnectoritisnecessarytoassurewhichtypeRS232or
RS485 or M‐Bus communication is used. Otherwise the communication module can be
damagedordestroyed.Seeconnectiondiagramsbelow.

4 Corresponding data are stated on the instrument label, regarding the selected communication.
Connectorterminalsaremarkedonthelabelontheuppersideof the instrument. More detailed
informationoncommunicationisgiveninchapterCommunicationonpage50.
RS232
RS232communicationisintendedfordirectconnectionoftheMeasuringcentretothepersonalcomputer.For
properoperationitisnecessarytoassurethecorrespondingconnectionofindividualterminals(seetableonnext
page).
RS485
RS485 communication is intended for connection of devices to network where several devices with RS485
communicationareconnectedtoacommoncommunicationinterface.WesuggestusingoneoftheISKRA,d.d.
