Wiring for direct connection to the IMC/W2
To receive uncorrected reads: Connect the red
wire to terminal block 3 (TB3 telemetry output)
GND1 (ground) position (B). Connect the white
and blue wires to the pulse output 1 position (A).
To receive corrected reads Connect the red
wire to the GND 2/3 (ground) TB3 telemetry
output position (C). Connect the white and blue
wires to the pulse output 2 position.
3. After completing the wiring connections, install
a cable tie to the meter cable just below the
exposed colored lead wires on the cable
insulation. Remove the excess cable tie using a
hand-held side-cutter pliers. The cable tie
performs as a cable strain relief to mitigate the
risk of destructive tension on the lead wires.
4. Tuck the three gel connectors and cable tie inside the module housing, as shown in the
placement illustration and schematic.
