1 RS232 connection
2 HART resistor 250 Ω
3 IPT-1* 3
Necessary components:
l IPT-1*
l PC with PACTware and suitable WIKA DTM
l HART modem
l HART resistor approx. 250 Ω
l Power supply unit
Note:
For power supply units with integrated HART resistance (inner
resistance approx. 250 Ω), there is no additional external resistance
necessary. Standard Ex separators are often provided with a
sufficiently high current limitation resistance. In such cases, the
modem can be connected in parallel to the 4 … 20 mA cable.
7 .2 Parameter adjustment with PACTware
Further setup steps are described in the operating instructions manual
"DTM C
ollection/PACTware" attached to each CD and which can also
be downloaded from our homepage. A detailed description is available
in the online help of PACTware and the WIKA DTMs.
