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.
