format: 7-bit, Even parity, 1 stop bit (7, E, 1); RTU data format: 8-bit, Even
parity, 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 settings and 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-AN04NANN 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.

Mode 0 of CR#1: GAIN = 5V (2,000LSB), OFFSET=0V (0LSB)
Mode 1 of CR#1: GAIN = 6V (2,400LSB), OFFSET=2V (800LSB).
GAIN: Set range of voltage output value when digital input value is
K2,000 should be -4V~+20V(-1,600LSB ~+8,000 LSB).
OFFSET: Set range of voltage output value when digital input value is K0
