Note that ANY transmission from the Computer Interface Port may be instantly
halted by application of an
ESCAPE (ESC)
command, which is described in Sec-
tion 1.H.2(d), below.
Specific forms for each command in Table 1.2 are given in the following section.
Optional formatting of transmissions is treated in Section 1.H.3. For complete
instructions on connecting an external receiving device—computer, terminal,
printer, recorder, etc.—to your System 10’s Computer Interface Port, see Section
2.B of this Guidebook.
Note here that
a.
Each of the commands in Table 1.2 is a “RUN-TIME” COMMAND and may be
entered either via the System 10’s plug-in keyboard (if present) or via its Com-
puter Interface Port.
Regardless of the means of entry, the
DUMP (DMP)
,
SNAPSHOT (SNP)
,
STREAM (STR)
, and
HARD COPY (HCY)
commands will always produce an
output from the Computer Interface Port only. These commands will never
cause requested data to be displayed on the system “billboard,” even when
they are entered through the keyboard.
The
CHANNEL (CHN)
and
LIMIT ZONE (LZN)
commands, on the other hand,
will produce an appropriate billboard response, but only when they are
entered via the keyboard—in which case no output from the Computer Inter-
face Port will be produced. When entered via the Computer Interface Port,
the
CHN
and
LZN
commands will, like the other DATA INTERROGATION
COMMANDS, produce appropriate output from that port (only).
b.
When using the multichannel or “range” (
x TO y
) form of the
DUMP (DMP)
,
SNAPSHOT (SNP)
,
STREAM (STR)
,
HARD COPY (HCY)
, and
LIMIT ZONE
(LZN)
commands, you should take care that the specified range of data chan-
nels to be transmitted is within or equal to the system’s currently specified
SCAN RANGE (see Section 1.F.2).**
c.
Every data value transmitted in response to one of the above commands can
take a maximum of seven characters, in addition to a minus sign, if applicable.
Maximum data precision is one part in ±32767 (16 bits). Scaling multiplier fac-
1-44

* Transmission of “all scanned channels” includes Channel Nos. 998 (TIME) and 999 (DATE).
** Unless, of course, you deliberately want the transmission to include unscanned and therefore
“frozen” data values, or DOWNLOAD PSEUDOCHANNELS that are outside the scan range.
