Ship Latitude (decimal degrees) or northing (meters); stored only

Magnetometer Z

{0}

[character zero between delimiters] Non-zero fish depth. Isis
accepts this depth value of if it is non-zero and there is no
manual depth set.

{DOT}

Distance off track (meters)

{KP}

KP (Kilometer post) (Kilometers)

{align=n}

The template token {align=n} causes Isis to set an absolute
parsing point in the input string. Alignment occurs after the nth
character. If the alignment value is 0, as in {align=0}, the token
causes processing to start with the first character in the input
string. If {align=} is given without specifying n, 0 (zero) is used
as the value. If n is specified to be negative or beyond the size of
the current input string, further processing halts at that point. Any
processing that happened before the {align=n} token was
encountered, still occurs. See ‘Examples of Character
Alignment’

on page 53.

{bf}

Bearing to Fish (degrees). This is the same as the > token.

{d}

Pressure in decibars. Value is converted to psia by multiplying by
1.45038. Fish depth then is computed as described for {p} in this
table.

{hy}

Yaw Heading. Yaw is computed to be (0.99 * old value + 0.01 *
new value), which performs an exponential-decay smoothing.

{h}

Heave. When processing multibeam data, distance below the
sea surface is computed to be (depth offset + sensor depth -
heave).

{i}

Changed every occurrence of the letters 'E' or 'e' to a blank
space. Useful in causing Isis to ignore scientific notation.

{KLEIN595} Makes Isis aware of strings coming from a Klein 595 sonar.

{le}

Electronics-bottle leak detector.

{lam}

Serial template to parse fish latitude stored with separate
degrees and minutes. Example: S 44 38.231 W 121 17.455. The
template to parse this is {lam}N{lom}E, where N is the token for
the fish position.

{log}

If 0 is sent over serial port, causes switch to display only. If 1 is
sent, data are logged.

{logn}

Behaves like {log}, except that when a 1 is sent, it will be
