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. CR7 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. CR7 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. CR7 sends Location and Checksum:
L+xxxxx Cxxxx
2718H REMOTE KEYBOARD - CR7 sends the prompt ">" and is ready to execute
standard keyboard commands (Section 5.2).
[loc. no.]I Display/change value at Input Storage location. CR7 sends the value
stored at the location. A new value and CR may then be sent. CR7 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 CR7
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 (if enabled) to the level determined by the password
entered (See *C Mode, Section 1.7). CR7 sends security level (0-3) and
checksum: Sxx Cxxxx
5.2 REMOTE PROGRAMMING OF THE
CR7
The CR7 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 PCs.
The CR7 is placed in the Remote Keyboard
State by sending "2718H" and a carriage return
(CR). The CR7 responds by sending a CR, line
feed (LF), and the prompt ">". The CR7 is then
ready to receive the standard keyboard
commands (Section OV3); it recognizes all the
standard CR7 keyboard characters plus the
decimal point. While in the Remote Keyboard
State, the CR7 sends the ASCII character
control Q (17 decimal) after each user entry.
Entering *0 returns the CR7 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,
awaiting another command. So, the user can
step back and forth between the
