HE4000 Encoding System Using a Remote Unit
The HE4000 uses the following command mnemonics to group various commands:
• The command mnemonics can be identified through entry of a single ? The
response is the list of mnemonic. Any mnemonic can be entered (followed by a
space) and then with a ? to get a list of commands associated with that group. For
any individual command, a ? may be entered to get a list of acceptable entries.
Entering any command with no entry will give the presently entered value.
Execute commands have an additional parameter which follows the command instruction.
4.2 Issuing Remote Commands
To issue a command from a remote unit, type the command at the remote prompt (>) with the
appropriate parameter, and then press the ENTER key. The following syntax is used:
<command> <parameter>
where:
•
<command>
consists of its mnemonic and the instruction; ensure that the command is
typed correctly and includes spaces and underscore (_) and period (.) characters as
appropriate
• There must be one space between the command and the parameter. A space is typed by
pressing the Space Bar key.
•
<parameter>
is the value pertaining to the command. Parameters can be numeric or
alphanumeric. No spaces should be typed after the parameter; doing so will result in an
error.
The HE4000 performs the required function and displays the prompt (>) when it is ready to
accept another command.
For example, to set the remote port baud rate to 1200 bps, issue the command
MC BAUD 1200
and press Enter. In this example:
• The command mnemonic is
MC
followed by a space
• The command instruction is
BAUD
followed by a space
• The parameter is
1200.
Query commands are issued by typing the command, without a parameter, and pressing Enter.
The HE4000 responds to the query by displaying information on the remote display.
For example, to query the remote port baud rate, issue the command
MC BAUD
and press
Enter. In this example:
• The command mnemonic is MC followed by a space
• The command instruction is BAUD followed by a space
• There is no parameter since this is a query command
The HE4000 responds by displaying the baud rate on the remote unit.
