Operation instruction
1.8.0
1.1.0
This remote command set is the default set available on the CPC8000-H. All commands must be
terminated with a <CR> and/or a <LF>.
A query command ends with a ? for queries. The data column represents the response of the
CPC8000-H. All response strings begi
n either with a space character or an “E” representing that there
is an error in the error queue. All response strings are terminated with a <CR> and a <LF>. The error
queue holds the last 10 errors identified.
For all commands (no ?), the data column represents the required parameters to be sent to the
CPC8000-H following the string in the command column. Any command that requires multiple
parameters must have the parameters separated by commas.
One of the first commands issued when starting remote communi
cations should be “Keylock Yes”.
This will disable the on-
screen keys and tabs, and place the “Keylock” label on the screen. Turning
keylock on prevents the potential conflicts that could occur if someone pressed an on-screen key,
either intentionally or by accident.
8.1 Remote Operation
Command and Query Format
Commands must be sent in ASCII format and terminated with either a carriage return <cr>,
linefeed <lf>, or both. Commands are not case sensitive. Each query returns a response. If an
error is detected the response will include an error flag.
Command or Query field
Unless otherwise specified, commands are typically converted to queries by appending a
question mark to the command.
Data field
The data field is either in ASCII {string} or numeric {value} form. In the case of multiple data
fields, commas are required to separate the fields. Queries do not have a data field. String
(text) or value (numeric) data are acceptable in any of the following formats:
o
Examples of {string} data: ON, OFF, mBar, inHg
o
Examples of {value} data: 1, 1.0, -5.678, 25.68324e-5
Command Set Definitions
In this manual a data entry made up of alpha characters is defined as a string, as opposed to
data containing only numbers, such as “Enter 1 for ON or 0 for OFF” where 1 and 0 are
defined as values.
Command
Any valid command or query is listed in the following tablesTable 6. For commands that take
boolean data the following strings are acceptable:
0
