To issue one of the commands listed in Table 6-1, type the command listed and press the Enter
key. The command will run and display the requested information or current setting, as appropriate.
For example, to view the current date setting type the letter D followed by the Enter key. The current
date will be reported. The sequence would appear like this:
D<cr>
D 2013-01-18<cr><lf>
To change a setting, the typical sequence is to type the command, press the space bar one time,
enter the new value in the same format that is displayed when checking the setting, and then
pressing the Enter key.
Continuing the example above, to change the date setting type the letter D, space, and then the
current date in YYYY-MM-DD format followed by the Enter key. A confirmation of the new date will
be reported. The sequence would appear like this:
D 2016-02-28<cr>
D 2016-02-28<cr><lf>
Pressing <Esc> or Q<cr> will exit terminal mode.
For a detailed listing of all commands and their formats, request the E-BAM 7500 document from
the Met One Instruments service department.
6.4.2 Computer Communication
In the Computer Communication mode, character echo is suppressed. This means when issuing
commands in this mode using a keyboard, the characters being typed will not be displayed on the
screen. The command format includes a checksum to verify data integrity.
The mode is entered whenever an <Esc> character is sent to the instrument. Commands are issued
using the following format:
<Esc>Cmd p1 p2*cs<cr>
Computer commands are prefaced with an <Esc> character followed directly by a command
(Cmd)... After the command there can be zero or more parameter field (p1 and p2) where each field
is separated by a space. The end of the message is signaled by the Checksum Delimiter character
(*) followed by the checksum itself (cs). Finally, the command is terminated with a carriage return
(<cr>).
A computer command example requesting the Model/Part/Revision numbers would look like this:
<Esc>RV*1234<cr>
All command responses are terminated with a checksum. The above command response would
have this format:
E-BAM, 82102, R1.0.0*01402<cr><lf>
CPLD, 81699, R1.0.0*01035<cr><lf>
For a listing of all commands and their formats along with additional in-depth Computer
Communication details, consult the E-BAM 7500 document contained on the CD included with the
sampler or contact the Met One Instruments, Inc. service department. See section 1.2.
