2 Installation and Configuration
5 DIP SW2 is used to set the Modbus address. For further information regarding Modbus
configuration, refer to Section 4.1., “Modbus Implementation Basics” on page 29 .
a If you are communicating via Modbus, you only need to set the Modbus address via
SW2. The Modbus address should be a number between 1 and 254. Adjust the individual
switches until their sum equals the Modbus address. The following illustration shows the
values of the DIP switches on the SW2 block as well as two examples of how the DIP
switches would be set for specific unit addresses.

2.4.4 JMP - Termination Jumper
The termination jumper, labeled JMP, is located next to TB4. It is used to designate the end of
the line unit In a daisy chain. The SeaHawk 10K ships with the jumper in the non-terminated
position - over the two pins closest to the device enclosure. If your SeaHawk 10K is the only
device in the application, or if it’s not the last unit in the daisy chain, leave the jumper where it
is. If your unit is the last device in a daisy chain, move the jumper so it is over the two pins
nearest the end of the board.
