  * Values of BFM #0, #23 and #24 are copied to EEPROM memory of the LX3V-4AD. BFM #21 and BFM #22 are only copied when data is written to the gain/offset command buffer BFM #22. Also, BFM #20 causes writing to the EEPROM memory. The EEPROM has a life of about 10,000 cycles (changes), so do not use programs which frequently change these BFMs.
  * Because of the time needed to write to the EEPROM memory, a delay of 300 ms is required between instructions that cause a write to the EEPROM. Therefore, a delay timer should be used before writing to the EEPROM a second time.

 . The number of averaged samples for CH1 and CH2 is set to 4 by writing 4 to BFM #1 and #2 respectively.
 . The operational status of the LX3V-4AD is read from BFM #29 and output as bit devices at the LX3V main unit. If there are no errors in the operation of the LX3V-4AD, then the averaged data BFM’s are read.
