If using rated armor cable, wires are already provided. Skip to
step 4.
4. Strip back the jacket and insulation of the current loop output and
serial cables just enough to connect to the mating terminal block.
5. Connect the 4-20 mA current loop IOUT1/IOUT2 output wires to
terminals 6 and 8, as shown in Figure 3–4 and Table 3–1.
6. Connect the serial cable wires to the appropriate terminals according
to Table 3–2 on page 3–11 (TB1).
7. To complete the connection, connect the other end of the current
loop wires to a current loop receiver and the external serial cable to
a serial port on your computer.
