SECTION 5. TELECOMMUNICATIONS
5-3
[YR:DAY:HR:MM:SS]C RESET/SEND TIME - If time is entered the time is reset. If only 2 colons are
in the time string, HR:MM:SS is assumed; 3 colons means DAY:HR:MM:SS.
If 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
[no. of arrays]D ASCII DUMP - If 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.
E End call. Datalogger sends CRLF only.
[no. of loc.]F BINARY DUMP - Used in TELCOM (PC208). See Appendix C.
[F.S. loc. no.]G MOVE MPTR - MPTR is moved to specified Final Storage location. The
location number must be entered. 21X sends Location and Checksum:
L+xxxxx Cxxxx
2718H REMOTE KEYBOARD - 21X sends the prompt ">" and is ready to execute
standard keyboard commands (Section 5.2).
[loc. no.]I Display/change value at Input Storage location. 21X sends the value stored
at the location. A new value and CR may then be sent. 21X sends
checksum. If no new value is sent (CR only) the location value will remain the
same.
3142J TOGGLE FLAGS AND SET UP FOR K COMMAND - Used in the Monitor
Mode and with the Heads Up Display. See Appendix C for details.
K CURRENT INFORMATION - In 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 Final Storage Data if requested by the J command.
Used in the Monitor Mode and with Heads Up Display. See Appendix C.
[Password]L Unlocks security (See *C Mode, Section 1.7). 21X sends ON or OFF and
checksum: OFF Cxxxx
5.2 REMOTE PROGRAMMING OF THE
21X
The 21X can be programmed via
telecommunications using the PC208 software
or manually through the Remote Keyboard
State.
The PC208 Datalogger Support Software was
developed for use with IBM or compatible PC's.
Datalogger programs are developed on the
computer using the program editor EDLOG and
downloaded to the datalogger with the terminal
emulator program TERM.
The 21X is placed in the Remote Keyboard
State by sending "2718H" and a carriage return
(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 all the
standard 21X keyboard characters plus the
decimal point. While in the Remote Keyboard
State, the 21X sends the ASCII character
control Q (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 still within
Telecommunications. Entering *0 exits the
Remote Keyboard and returns the datalogger to
the Telecommunications Command State,
