Appendix C – Multiple wet-section setup
A single Navigator 540 transmitter can monitor up to 4 wet-sections. The wet-sections can be any combination of the three Navigator
500 parameters – sodium, low level dissolved oxygen and hydrazine. Note that the transmitter cannot monitor more than 1 wet-
section if the wet-section is a multi-stream sodium.
If an additional wet-section is added to a transmitter, the procedures in Sections C.1 and C.2 must be performed.
C.1 Configuring the device address
The unique device address assigned to the wet-section (1 to 4), enables the transmitter to identify the wet-section on the data
transmission link. Each wet-section must have its own unique address. The address can be set by SW1 as shown in Table C.1 and
Fig. C.1. LEDs D4 and D5 indicate the slave address of the PCB.
C.2 Serial connections
Each wet-section must be connected in a 'daisy chain' format as shown in Fig. C.2.

Note.
The total cable length between the transmitter and the last wet-section must not exceed 30 m (98 ft.).
