>WP00001<CR> [Your original input]

> [Channel Master response to a valid, no-output command]

If you enter a valid command that produces output data, the Channel Master

executes the command, displays the output data, and then redisplays the “>”

prompt. Some examples of commands that produce output data are

? (help

menus), CS (start pinging), PS (system configuration data), and PA (run built-

in tests).

If the command is not valid, the Channel Master responds with an error

message similar to the following.

>WPA<CR> [Your input]

>WPA ERR 002: NUMBER EXPECTED<CR><LF> [Channel Master response]

After correctly entering all the commands for your application, you would

send the CS-command to begin the data collection cycle.

10.1.2 Data Output Processing

After the Channel Master completes a data collection cycle, it sends a block

of data called a data ensemble. A data ensemble consists of the data col-

lected and averaged during the ensemble interval (see “TE – Time Per En-

semble,” page 83). A data ensemble can contain header, leader, velocity,

correlation magnitude, echo intensity, percent good, status, surface track

fields, and firmware version data.

Channel Master output data can be in either hexadecimal-ASCII (Hex-

ASCII) or binary format (set by “CF – Flow Control,” page 54). The Hex-

ASCII mode is useful when you use a terminal to communicate with, and

view data from the Channel Master. The binary mode is useful for high-

speed communication with a computer program. You would not use the bi-

nary mode to view data on a terminal because the terminal could interpret

some binary data as control codes.

NOTE. WinHADCP supports PD0, PD14, and PD19 Output Data Formats

(see “PD – Data Stream Select,” page 77).

When data collection begins, the Channel Master uses the settings last en-

tered (user settings) or the factory-default settings. The same settings are

used for the entire deployment.

The Channel Master automatically stores the last set of commands used in

RAM. The Channel Master will continue to be configured from RAM until

it receives a CR-command or until the RAM loses its backup power. If the

Channel Master receives a CR0 it will load into RAM the command set you

last stored in non-volatile memory (semi-permanent user settings) through

the CK-command. If the Channel Master receives a CR1, it will load into

RAM the factory default command set stored in ROM (permanent or fac-

tory settings).
