Section 5. Programming the Datalogger

Output Mode:

0No output format string

1Convert location to ASCII floating point. Add character/delimiter between values if enabled. The last value will not have a delimiter after it.

2Convert location to ASCII hex pair. Add character/delimiter between values if enabled. The last value will not have a delimiter after it.

3Convert location to 8-bit binary. Add character/delimiter between values if enabled. The last value will not have a delimiter after it.

4Convert location to 16-bit binary. Add character/delimiter between values if

enabled. The last value will not have a delimiter after it.

8Transmit a user-defined string 0-255 or fixed string 256-511.

9String type formatter; this is used where input; location data is to be transmitted in a complex format. See Output Formats in Section 3.

String Number or Delimiter Character:

If output mode 9 is chosen this is the string number 0..255. If the string is not allocated then the formatter will not operate. If mode 8 is chosen, then this is the user defined string 0-255 or fixed string 256-511. If output modes 1 to 4 are chosen, then this specifies the delimiter character as an ASCII code 0..255. 999 means character not enabled.

Second Command Option (Parameter 6)

This is used for filter set-up if data is expected back after output.

Input mode

String number or character/delimiter code

x x x x

Input Mode:

0No filter

1Convert any ASCII numbers to Campbell Scientific floating point up to the termination character if set

2Convert any ASCII hex pair to Campbell Scientific floating point up to the termination character if set

3Convert 8-bit binary number to Campbell Scientific floating point up to the termination character if set

4Convert 16-bit binary number to Campbell Scientific floating point up to the termination character if set.

8Transmit a user-defined string 0-255 or fixed string 256-511

9String filter type. See Filter Strings in section 3.

String Number or Character Code

If input mode 9 is chosen, this is the user-defined filter string number 0..255 or fixed filter string 256..511 used for the filter; if the string is not allocated the filter will not operate. If input mode 8 is chosen, this number is the defined string 0-255 or fixed string 256-511. If input modes 1 to 4 are chosen, this is the termination character as an ASCII code 0..255; 999 means character not enabled.

NOTE

Min. delay for floating point data = floats*3*(characters*0.26*ports).

 

Min. delay for strings = characters*0.26*ports.
