Buffer Memory List (BFM)
4AD incorporates the following buffer memories.
→ For a detailed description of the buffer memory, refer to Section 5.4 and subsequent sections.
*1.
If power failure occurs, the EEPROM will retain its data.
*2.
To specify the input mode of each channel, set each digit using hexadecimal numbers 0 to 8 and F.
*3.
Use b0 to b3.
