SM - RDS3 Mode Select

Purpose Sets the RDS3 Mode.
Format SMn
n = 0 (Off), 1 (RDS3 Master), 2 (RDS3 Slave), 3 (NEMO)
Range
Default SM0
Recommended Setting. Special applications only.
Description SM sets the RDS3 Mode. SM0 turns off the RDS3 mode and disables all other commands
on this menu. SM1 sets the RDS3 Master mode and enables the SA, SI, SS, and SW
commands. SM2 sets the RDS3 Slave mode and enables the SA, SS, and ST commands.
SM3 sets the NEMO Mode and enables the SW command.
When the SM command is used, the communication switch on the H-ADCP's PIO board must be
in the RS232 position.

SS - RDS3 Sleep Mode

Purpose Sets the RDS3 Sleep Mode.
Format SSx
Range x = 0, 1 (0 = No Sleep, 1 = Sleep)
Default SS0
Recommended Setting. The default setting for this command is recommended for most applications.
This command has no effect unless SM = 1 or 2
Description This command sets the RDS3 Sleep Mode. When x is set to No Sleep, the instrument re-
mains awake while waiting for the next ping time (or synchronization pulse) in a loop.
When x is set to Sleep, the instrument sleeps between pings (or synchronization pulses.)
There are limitations to using the Sleep Mode. A TRDI WH, setup as a slave, can only
synchronize to within 2.5 ms of the Master. When the Slave is in No Sleep Mode, the slave
can ping to within 500 microseconds of the master. The benefits of power saving cost are
synchronization accuracy.
