C R # 2 8 , 2 9 :
Adjusted GAIN value of CH1 ~ CH2
1. The adjusted GAIN value for CH1 ~ CH2 on the ELC-AN02NANN, representing the
analog output voltage or current when the digital output value is 2,000. Default = K2,000.
Unit: LSB.
2. The adjustable range of voltage: -4V ~ +20V (0
LSB
~ +4,000
LSB
).
3. The adjustable range of current: -8mA ~ +40mA (0
LSB
~ +4,000
LSB
).
4. Please note that: GAIN value – OFFSET value = +400
LSB
~ +6,000
LSB
(voltage or
current). When GAIN – OFFSET is small, the resolution of output signal will be finer and
variation on the digital value will be greater. When GAIN – OFFSET is large, the
resolution of output signal will be grainier and the variation on the digital value will be
smaller.

Note: Each fault code will have corresponding bit (b0~b7). Two or more faults may happen
at the same time. 0 means normal and 1 means having fault.
C R # 3 1 :
RS-485 communication address setting
The settings for the RS-485 communication address. Range: 01 ~ 255. Default = K1. This
setting is only valid for RS-485 communication and will be invalid when connected to an ELC
controller.
C R # 3 2 :
Communication speed (baud rate) setting
The interface settings for the RS-485 communications: data rate: 4,800, 9,600, 19,200,
38,400, 57,600 and 115,200bps (bits per second). Default = H’0002.
b0 = 1:
4,800 bps
b1 = 1:
9,600 bps (default)
b2 = 1:
