TP – Time Between Pings
Purpose Sets the time interval between pings in an ensemble.
Format TPmm:ss.ff
Range mm = 00 to 59 minutes
ss = 00 to 59 seconds
ff = 00 to 99 hundredths of seconds
Default TP00:00.60
Recommended Setting. Set using WinHADCP.
Description The TP command sets the time interval between the start of
one ping and the start of the next within an ensemble. If TP is
very short, the Channel Master will generate the next ping as
soon as the last ping completes.
The time needed to complete a ping may not be easy to pre-
dict. It is controlled by sound propagation time (speed of
sound x max range x 2), processing overhead, and other fac-
tors. The max range is controlled by commands (WF, WN,
WS) and the environment (for example, range to the surface
for the vertical beam). The vertical beam ping consists of
multiple sub-pings.
Example TP00:00.10 sets the time between pings to 0.10 second.
NOTE. The Channel Master automatically increases TE if WP x TP > TE.
