Model PIM-3 6-5
If the PIM-3 then does not receive a carriage return within
10 seconds of receiving the "#" character, the PIM-3
leaves its receive mode. Likewise, if you believe that any
stray or garbled characters have been sent to a PIM-3,
sending the PIM-3 a carriage return will also cause the
instrument to leave its receive mode.
6.6 Response Format
Some PIM-3 commands will give a response over the
serial communications link, and others will not. There are
three types of responses used by an PIM-3:
* "COMMAND ERROR", which is sent when
an PIM-3 has been asked to perform
an invalid command, or when invalid
information is given with a write oper-
ating parameter (“W”) command.
* a floating point number as the result of a
read operating parameter ("R") or
function ("F") command.
* other ASCII strings
To signal the end of a response, the PIM-3 will send a
carriage-return (ASCII code decimal 13) if the Auto-Line-
feed function is off, or a linefeed/carriage-return (ASCII
codes decimal 10, decimal 13) when the Auto-Linefeed is
on. The Auto-Linefeed status can be changed over the
serial communications link using the "
W2
" system com-
mand. For details on changing the Auto-Linefeed status,
see the "
W2
" command in Chapter 10, "System Com-
mands."
The DEFAULT pin can be used to temporarily change
a PIM-3’s Auto-Linefeed function to on. See Chapter 4,
“Mounting and Wiring” for more information.
