The wiring instruction below applies to all compatible measurement instruments
except the HMDW110 series (HMDW110 wiring is covered in section Wiring
HMDW110 with RDP100 on the facing page)
.

Use a single power supply to power the RDP100, and connect the power to the
measurement instrument through the RDP100. Connect the power pass-
through jumper on the RDP100 as indicated below.

l

DMT132/152, MMT162, DPT145/146: Connect wiring to port II.
Install the jumper on RDP100 to position 1-2.

l

DMT143: Connect wiring to port marked Digital. Install the jumper on
RDP100 to position 1-2.

l

HMP60/63/110/113: Connect to the M8 connector. Install the jumper
on RDP100 to position 2-3.

Caution: The RS-485 circuit of the compatible DMT, DPT, MMT, and
HMP transmitters is not isolated. Using the RDP100 and analog outputs
simultaneously is not supported.

Note: Connecting the jumper to position 1-2 allows the supply voltage to
pass through the RDP100 unregulated. Connecting the jumper to position
2-3 regulates the pass-through voltage to 7.5 VDC.
