Section 8. CR200(X) Configuration

The CR200(X) will time out and exit the terminal mode if it does not receive a

command within 12 seconds.

Enter a command by pressing the command followed by the carriage return.

The commands are:

Trap Code 16 Information

"OK" = memory ok

"2005-7-14 13:56:6=16" = memory failure, 16 denotes trap code 16,

date/time is when it occurred.

NOTE: When a trap code 16 happens, the datalogger suspends running

the program and the red LED flashes twice every scan interval. A trap

code of 16 means that the datalogger’s memory needs to be replaced.

8.3.4 Durable Settings

Many CR200(X) settings can be changed remotely over a telecommunications

link either directly or as part of the CRBASIC program. This convenience

comes with the risk of inadvertently changing settings and disabling

communications. Such an instance will likely require an on-site visit to correct

the problem. For example, digital cell modems are often controlled by a

switched 12 Volt (SW Battery) channel. SW Battery is normally off, so, if the

program controlling SW Battery is disabled, such as by replacing it with a

program that neglects SW Battery control, the cell modem is switched off and

the remote CR200(X) drops out of telecommunications.
