TP – Time Between Pings
Purpose
Sets the minimum time between pings.
Format
TPmm:ss.ff
Range
mm
= 00 to 59 minutes
ss
= 00 to 59 seconds
ff
= 00 to 99 hundredths of seconds
Default
TP00:01.00 (300 kHz), TP00:00.20 (600 kHz)
Recommended Setting.
Set using
SurfaceView.
Description
The H-ADCP interleaves individual pings within a group so they are evenly spread
throughout the ensemble.
During the ensemble interval set by TE, the H-ADCP transmits the number of pings set by
the WP-command. TP determines the spacing between the pings. If TP = 0, the H-ADCP
pings as quickly as it can based on the time it takes to transmit each ping plus the over-
head that occurs for processing. Several commands determine the actual ping time (WF,
WN, WS, and actual water depth).
Example
TP00:00.10 sets the time between pings to 0.10 second.
The H-ADCP automatically increases TE if (WP x TP) > TE.
Note that excessively short ping times will prevent keyboard input from being recognized.
TS – Set Real-Time Clock
Purpose
Sets the H-ADCP’s internal real-time clock.
Format
TSyy/mm/dd, hh:mm:ss
Range
yy
= year
00 to 99
mm
= month 01 to 12
dd
= day
01 to 31
hh
= hour
00 to 23
mm
= minute 00 to 59
ss
= second 00 to 59
Recommended Setting.
Set using
BBTalk
or
SurfaceView.
Example
TS98/06/17, 13:15:00 sets the real-time clock to 1:15:00 pm, June 17, 1998.
1. When the H-ADCP receives the carriage return after the TS-command, it enters the new time
into the real-time clock and sets hundredths of seconds to zero.
2. If the entry is not valid, the H-ADCP sends an error message and does not update the real-
time clock.
