Chapter 4 - Control from the Supervisory Port HCD-E1
Installation & Operation Manual
4-8 HCD-E1 Control Language 11/01/00 19:23
Commands can be entered only when the HCD-E1 control port working
prompt is displayed. The prompt is HCD>, and it always appears at the
beginning of a new line. The cursor appears to the right of the prompt.
Commands are case-insensitive, that is, you can type commands in either
lowercase or uppercase letters.
To correct typing errors, press the BACKSPACE key until the error is
cleared, and then type the correct command.
Use space as a separator between command fields and/or parameters.
Commands must end with a carriage return <CR>.
To cancel the current command, press CTRL-C. You will obtain the
HCD-E1 prompt again.
If AUTOBAUD is on, start any session by pressing the <CR> key three
times in sequence. This will ensure identification of terminal data rate.
At the start of a session, when password protection is on, the prompt
HCD-E1 displays is PASSWORD. This means that HCD-E1 is waiting for
the password before continuing. When you start entering the password,
HCD-E1 responds to your input with asterisks. After the correct password
is received, HCD-E1 sends the working prompt.
After the working prompt is displayed, the user can enter the desired
command. Full duplex communication with the terminal is necessary.
When HCD-E1 uses a non-zero node number, prefix any command
with: NODE<SP>'node number'<SP>, where 'node number' is the
three-digit node number. No response will occur until the node number
is received and acknowledged by the addressed HCD-E1.
Acknowledgment is indicated by the echoing of the node number part,
i.e. Node<SP>nnn<SP>, where <SP> stands for space.
At the start of a session, when password protection is on, you must
enter the password after the node number. After the correct password
is received, HCD-E1 sends the working prompt.
If password protection is off, this step is omitted and the working
prompt appears after the node number conditions are fulfilled.
The node number is in the range of 1 through 255 (0 indicates that the
selective addressing function is disabled). To set or change the node
number, use the DEF NODE command.
Command evaluation starts only when you press the <CR> key after the
last page of the data form.
