Summary:
The DATATAKR driver uses the immediate schedule command "X" to upload data.  How can I use the A, B, C and D schedules to log data without these schedules emitting unsolicited data which may interfere with the normal operation of the DATATAKR driver? 

Solution:
The return of data to the host can be controlled for individual channels using the No Return channel option.  The No Return channel option will disable the return of data from selected channels when the Return Data Switch is enabled.

For example, consider the following A schedule configuration.

/R

RA2S 1TK (NR) 2TK LOGON

The NR (No Return) option prevents the first thermocouple channel returning data.  If using A, B, C and D schedules when also using the DATATAKR driver, all channels of these schedules should be prevented from returning data.  See the DATATAKER logger reference manual for more information.
