3.2 The Remote interface

Metrohm 838 Advanced Sample Processor, Appendix

69

In order to simplify the use of Remote commands, particularly when

several devices are linked together with Metrohm cables, predefined bi-

nary patterns are available as command parameters for the commands

CTL and SCN for standard conditions. These are:
