Vaisala Indigo500 Series - Probe Connection Wiring

When configuring the non-display transmitter, the Ethernet connector can be
used without taking the cable through the cable gland. Always wire through the
cable gland for more long-term wiring.
When you insert the cable through the gland parts, also remove the split bushing
(3) inside the nylon seal (2) to make the cable fit through the seal. Then place the
bushing around the cable and push it back inside the seal. See the following
figure.
