High/low byte exchange of CRC checksum (only valid in RTU mode)
b15:
Switch between ASCII/RTU mode. 0: ASCII (default); 1: RTU. ASCII data
format: 7-bit, Even, 1 stop bit (7, E, 1); RTU data format: 8-bit, Even, 1 stop
bit (8, E, 1). This setting is only valid for RS-485 communication and will be
invalid when connected to an ELC controller.

: Returning to default setting; modifying OFFSET/GAIN authorization
For authorization of OFFSET/GAIN tuning. The latched function will store the output setting
in the internal memory before the power is removed. Default setting = H’0000. For example,
CH1 on the ELC-AN02NANN module:
1. When b0 = 0, the user is allowed to modify CR#22 (OFFSET) and CR#28 (GAIN) for
CH1. When b0 = 1, the user is not allowed to modify CR#22 (OFFSET) and CR#28
(GAIN) of CH1.
2. b1 represents whether the OFFSET/GAIN tuning registers are latched. b1 = 0:
OFFSET/GAIN tuning registers are latched; b1 = 1: OFFSET/GAIN tuning registers are
non-latched. This function is only valid when using RS-485 communications.
3. When b2 = 1, all settings will return to default value except for CR#31 and CR#32.
