SECTION 5. TELECOMMUNICATIONS

5-4

[loc. no.]I

Display/change value at Input Storage location. CR10X sends the
value stored at the location. A new value and CR may then be sent.
CR10X 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.

2413J

SET UP FOR K COMMAND - Used in the Monitor Mode and with the
Heads Up Display. Similar to the 3142J command but does not
toggle flags and ports. See Appendix C for details. (Available first in
CR10X OS Version 1.10; also indicated by “V4” returned to the A
command, see above.)

CURRENT INFORMATION - In response to the K command, the
CR10X 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 for details.

[Password]L

Unlocks security (if enabled) to the level determined by the
password entered (See * C Mode, Section 1.7). CR10X sends
security level (0-3) and checksum:

Sxx Cxxxx

[X]M

Connect to Storage Module with address 'X' and enter the Storage
Module's Telecommunications Mode (see Storage Module manual). The
Storage Module can also be accessed through the * 9 Commands while in
the Remote Keyboard Mode (Section 4.5 and the Storage Module
manual).

Connect phone modem to RF modem at phone to RF base station.

Command to set 4.9152 MHz crystal coefficients. Coefficients are
set at the factory and normally should not be altered. Displays:

E clock Hz - 1.2288 MHz

to give better resolution. Also, gets rid of out of bounds check that
used to load default back in. If not set, P27 and other timing
instructions will have problems.

19287P will display the 2 coefficient numbers for you (e.g. 0.8944
.8133). If the 2 numbers are -99999, the datalogger needs to be
calibrated.

19287:800P will calibrate it for you if your crystal is exactly 1.2288
MHz E Clock. This temporary fix will improve the performance of a
datalogger that failed the 19287P test.
