Module modes
Table A-24 contains the codes for the module modes, which you enter in byte 0 of
data record 128 (see Figure A-14).
Table A-24 Codes for the modes of SM 331; AI 8 x 16 bits
Interference suppression
Table A-25 contains the codes for the different frequencies, which you enter in byte
1 of data record 128 (see Figure A-14). Note that 4-channel mode only functions if
interference frequency suppression of 50, 60 and 400 Hz is set.
