Commands
4-2
Commands consist of single keywords, possibly followed by an
operand separated by a "=", for example: BAUD or TUBE=42.
Commands may be abbreviated to as few as three characters.
Spaces are ignored. Backspace, (ASCII character 8), may be used
to correct mistakes. Commands are not case-sensitive.
Commands are processed when a carriage return is received.
Multiple commands may be sent on a line, separated by semi-
colons (;), for example: NEXT;NEXT;RSVP. Total line length must
not exceed 80 characters. Errors occurring from any command do
not stop the execution of the remaining commands on line.
The fraction collector must be in remote mode to do anything
other than read values. See REMOTE on page 4-4 for more infor-
mation. Program parameters cannot be changed while a run is in
progress. Also, changes to any parameter currently being edited
on the fraction collector display will not be effective.
Errors relating to the syntax of commands result in problem
message responses. See Problem Responses on page 4-17.
Hardware related errors (warnings and failures) are indicated by
the display and audio output of the unit, and can be detected
serially using the STATUS command.
The fraction collector's response time to most commands is 50
milliseconds. One exception is commands that require some
mechanical action such as arm movement. Mechanical actions
normally do not exceed 4 seconds. Other exceptions are noted
where applicable.
The following is a list of all fraction collector serial commands,
with a brief description and example of the use for each
command. For some commands, no response is required or
expected from the unit. The examples show this as Response:
(none).
CLEAR This command resets the unit. It is equivalent to
switching the unit to standby and then back to operate.
Example: Command:
Response:
CUE=n This command enables or disables the sending of a ">"
prompt character when the unit is finished processing a
command line and is ready for another. This "line pacing" can be
used by many terminal programs to avoid downloading com-
mands faster than the unit can execute them. CUE=1 will enable
the prompt, CUE=0 will disable it. CUE=0 is set when unit is
switched to OPERATE.
