Section 8. <strong>CR200</strong>(X) Configuration<br />
The <strong>CR200</strong>(X) will time out and exit the terminal mode if it does not receive a<br />
command within 12 seconds.<br />
Enter a command by pressing the command followed by the carriage return.<br />
The commands are:<br />
Commands Action (what returns)<br />
A<br />
Trap Code 16 Information<br />
"OK" = memory ok<br />
"2005-7-14 13:56:6=16" = memory failure, 16 denotes trap code 16,<br />
date/time is when it occurred.<br />
1 Get clock<br />
NOTE: When a trap code 16 happens, the datalogger suspends running<br />
the program and the red LED flashes twice every scan interval. A trap<br />
code of 16 means that the datalogger’s memory needs to be replaced.<br />
2 Set clock (after setting clock, exits terminal mode)<br />
3 Status codes<br />
4 Status table<br />
5 Public table (real time values)<br />
6 Most recent record from user defined table 1<br />
7 Most recent record from user defined table 2<br />
8 Most recent record from user defined table 3<br />
9 Most recent record from user defined table 4<br />

Goes into the SDI-12 terminal mode and remains there<br />
8.3.4 Durable Settings<br />
Many <strong>CR200</strong>(X) settings can be changed remotely over a telecommunications<br />
link either directly or as part of the CRBASIC program. This convenience<br />
comes with the risk of inadvertently changing settings and disabling<br />
communications. Such an instance will likely require an on-site visit to correct<br />
the problem. For example, digital cell modems are often controlled by a<br />
switched 12 Volt (SW Battery) channel. SW Battery is normally off, so, if the<br />
program controlling SW Battery is disabled, such as by replacing it with a<br />
program that neglects SW Battery control, the cell modem is switched off and<br />
the remote <strong>CR200</strong>(X) drops out of telecommunications.<br />
