Deployment Setup page

, tap 

File

 and 

Export 

PDC4 configuration file

.  After some seconds the 

parameter channels will be listed in the order that 
they will be sent. 

Tap the plus sign next to each of the parameters to get 
more information about the various channels, like the 
coefficients A, B, C and D and whether the resolution 
is 10 or 20 bit (refer TD220c 

RDCP Primer)

. 

The coefficients can then be put into the Display 
Program 3710.   

To make the transfer of information to the PC easier, 
the data can be stored as Station Info to MMC by 
tapping the STI- image. You can save the .sti-file in 
the 

File

 directory.     

Figure 1-26 The PDC-4 export utility

 

Because of the slow PDC-4 transfer rate we advise that you limit the number of channels (e.g. 
by reducing the amount of column cells) and avoid using a large cell overlap when configuring 
PDC-4 real-time output.  The PDC-4 transfer can however work satisfactory in many situations, 
for instance in harbour installations. Some application examples are included in TD220c

Real-Time Clock System 

The RDCP 600 employs a two-clock system comprising a main Real-time Clock (RTC) and a 
backup RTC. The reason behind this scheme is that the main RTC is embedded within the main 
StrongARM processor and loses power when the instrument is switched off. The backup RTC, 
on the other hand, includes an embedded lithium battery that is activated when the instrument is 
switched off to supply power to the clock system during down periods. The lithium battery has 
sufficient capacity for 10 years of operation. 

The main RTC is the more accurate of the two. It comprises an advanced pulse skipping 
mechanism that allows the system to skip or add one or more pulses from the 32768 Hz base 
oscillator during a 1024 seconds period to compensate for small errors in the oscillator base. 

At power-up, the instrument will read the backup RTC and copy its time base into the main 
RTC. From there on the system uses the main RTC as time base. The result is that the more 
accurate main RTC is used during a deployment until 

 power again is switched off.
