The terminal blocks for the relays are labeled on the board as RELAY 1
through RELAY 4. The relay terminal blocks should be wired for either
NO or NC circuits. Figure 3–6 shows RELAY 1 is wired for a NC circuit.

blue-banded ends, and the upstream transducer has red-banded ends.
Refer to the figure below. The symbol is on both pairs of terminals and
indicates which terminals should connect to the center wire conductors and
which should connect to the coaxial shields.
