Register 40002, will take
effect after reboot (reset).
3.5 Reg. 40003: Change Parity of the RS485 port
Register 40003 contains the parity of the RS485 port. The default is no parity. The data field must
have a value from 0 to 3, which corresponds to the following parity:

0 = none

1 = even

2 = odd
 3 = mark

3.6 Reg. 00001: Update Real-Time Data from Diver
Setting this register forces the Diver-MOD to get real-time values, i.e. pressure, temperature and
conductivity (if applicable), from the connected Diver. The updated real-time values must be read
from registers 30201 – 30216.
The type of conductivity is either normal conductivity or specific conductivity at 25 °C depending on
the setting in the CTD-Diver.

0x05 00001 1 0xFF00 Register 00001 can also be a
broadcast (address 0) to all
Diver-MODs. In case of a
broadcast, wait at least
500 ms before the next
instruction.
2 Read real-time values
from all channels (longs)
0x04 30201 6 -
Register 3020x, convert to
longs (two registers per long)
3 Read real-time values
from all channels (float) 0x04 30211 6 - Register 3021x, convert to
single floats (two registers
per single float)
