Connector P3
Ethernet RJ 45. Connect the instrument to the local network by passing an ethernet cable through
the ethernet cable gland (gland location illustrated in Figure 1 on page 7) and connecting to the
P3 connector illustrated in Figure 3.
Measurement board
The different measurement boards for the EC and TC sensors are illustrated in Figure 5 and
Figure 6. The type of board is easily identified by the color of the J8 connector. For EC boards this
connector is colored orange, and for TC boards it is colored black.
N O T I C E
It is extremely important that sensors are connected to the correct measurement board. Connecting a TC sensor
to an EC measurement board (and vice versa) will cause irreparable damage to the measurement board.
