Fig. 29: Connecting the PC to the signal cable
1 RS232 connection
2 VEGAPULS 68
3 HART adapter cable for VEGACONNECT 3
4 HART resistance 250 Ohm
Necessary components:
l VEGAPULS 68
l PC with PACTware™ and suitable VEGA-DTM
l VEGACONNECT 3 with HART adapter cable (art.
no. 2.25397)
l HART resistance approx. 250 Ohm
l power supply unit
Note:
With power supply units with integrated HART resis-
tance (internal resistance approx. 250 Ohm), an addi-
tional external resistance is not necessary (e.g.
VEGATRENN 149A, VEGADIS 371, VEGAMET 381). In
such cases, VEGACONNECT 3 can be connected in
parallel to the 4 ... 20 mA cable.
