ID Code
Stores the vertical beam profile leader identification word (0x0F01h)

# Bins
Stores the number of bins (
ZN – Vertical Beam Number of Bins
Scaling: LSD = 1 bin; Range = 1 to 200 bins
9-12
5,6
Ping/ensemble
Stores the number of pings to average together in each ensemble (
). If ZP = 0, the RiverPro/RioPro does not collect vertical beam
profile data.
Scaling: LSD = 1 ping; Range = 0 to 999 pings
13-16

Bin size
Stores the vertical beam profile bin size (cm) (
Scaling: LSD = 1 cm; Range 2 to 500 cm
17-20

Distance to bin 1
middle
Contains the distance to the middle of bin 1. The distance to the middle of bin 1 is
determined by: blank + (xmt lag binSize)/2. Blank and bin size are
affected by the speed of sound; xmt length and lag use a fixed speed of sound value.
ZF – Vertical Beam Blanking Distance
determines blank.
determines bin size, which also determines xmt length,
unless the
is used.
ZV – Vertical Beam Ambiguity Velocity
determines lag length by setting the ambigu-
ity velocity.
Scaling: LSD = 1 centimeter; Range = 0 to 500 cm

Xmit length
Stores the vertical beam Transmit Length in cm.
Scaling: LSD = 1 centimeter; Range = 2 to 500 cm
29-32
15-16
Lag length
Lag Length in cm. The lag is the time period between sound pulses. This is varied as
required by the RiverPro/RioPro.

# Code elements
Contains the number of code elements in the transmit pulse.
