REMOTE PROGRAMMING OF THE
21X
The 21X
carp
be programmed
via
telecommu(ications using the PC208 software
or manually lthrough
the Remote Keyboard
State.
The PC208 patalogger Support Software was
developed
fpr use with IBM or compatible PC's.
Datalogger programs are developed on the
computer uging the program editor EDLOG and
downloade{ to the datalogger with the terminal
emulator pr$gram TERM.
The
21X is placed
in
the Remote Keyboard
State by serirding
'2718H" and
a
carriage return

TELECOMMUMCATIONS
RESET/SEND
TIME - lf time
is
entered the time is
reset.
lf only 2 colons are
in
the time string, HR:MM:SS is
assumed;
3
colons means DAY:HR:MM:SS.
lf only
the C
is
entered,
time is unaltered. 21X returns year, Julian day,
hr:min:sec, and
Checksum: Y:xx Dxxxx Txx:xx:xx Cxxxx
ASCII DUMP
-
lf necessary,
the MPTR is advanced to the next start of array.
21X sends
the number of arrays specified (no number defaults
to
1) or
the
number
of
arrays between MPTR and Reference, whichever is smaller,
CRLF, Location, Checksum.
End
call.
Datalogger sends CRLF only.
BINARY DUMP
- Used
in
TELCOM
(PC208).
See
Appendix
C.
MOVE MPTR - MPTR is moved to specified Final Storage
location.
The
location number must be
entered. 21X sends
Location and Checksum:
L+xxxxx Cxxxx
REMOTE KEYBOARD
-
21X sends
the prompt ">" and is ready to execute
standard keyboard commands (Section 5.2).
Display/change value
at lnput Storage
location.
21X sends the value stored
at
the location. A new value and CR may then be sent. 21X sends
checksum. lf no new value
is
sent (CR only) the location value will remain the
same.
TOGGLE FLAGS AND SET UP FOR K COMMAND - Used
in
the Monitor
Mode and with
the Heads Up
Display.
See Appendix
C
for details.
CURRENT INFORMATION - ln response to the
K command,
the 21X sends
datalogger
time, user flag status, the data
at
the input locations requested
in
the J
command, and FinalStorage Data if requested by the J command.
Used in
the Monitor Mode and with Heads Up
Display.
See Appendix C.
Unlocks
security (See
.C
Mode,
Section
1.7).
21X sends ON or OFF and
checksum: OFF Cxxxx

I
(CR).
The
21X responds by sending a CR, line
feed (LF), and the prompt
">".
The 21X
is
then
ready
to receive the standard keyboard
commands (Section OV3); it recognizes
allthe
standard
21X keyboard characters plus the
decimal
point. While
in
the Remote Keyboard
State, the 21X sends the ASCII character
controlQ (17 decimal) after each user entry.
Entering
*0 returns the 21X to the
telecommunications command state.
It is important
to remember that the Remote
Keyboard State
is
stillwithin
Telecommunications. Entering
*0 exits
the
Remote Keyboard
and returns the datalogger to
the
Telecommunications Command State,
