Reset to factory
default settings and
inhibit modifying Gain
and Offset values
Factory setting H0000
Example for CH1:
1. When b0=0, user can set OFFSET and GAIN values
for CH1 (CR#18, CR#24). When b0=1, inhibit the
user from modifying OFFSET and GAIN values for
CH1.
2. b1=0 (factory setting, latched), b1=1 (not latched).
When b2 is set to 1, all settings will reset to factory
default settings.
#34 H’4054 O R System Version
Software version in hexadecimal. For example: H’010A
represents 1.0A.
#35~#48 System
use
O means latched. X means not latched. (available when using RS-485 communication, not available
when connected to MPU)
R means can read data by using FROM command or RS-485.
W means can write data by using TO command or RS-485.

Configuration Word
CR#1 is used to configure the two analog output channels. Each channel has four modes
that can be set individually. For example: setting CH1 to mode 2 (b2~b0=010), CH2 to mode
1(b5~b3=001). The factory setting of CR#1 is H0000.
C R # 1 0 , 11 :
The output values at CH1 ~ CH2
The decimal range for the analog outputs is: K0 ~ K4,000. Default = K0. Unit: LSB.
C R # 2 2 , 2 3 :
Adjusted OFFSET value of CH1 ~ CH2
1. The adjusted OFFSEST value for CH1 ~ CH2, representing the analog output voltage or
current when the digital output value is 0. Default = K0. Unit: LSB. Range: -2,000 ~
+2,000.
2. The adjustable range of voltage: -5V ~ +5V (-2,000
LSB
~ +2,000
LSB
).
3. The adjustable range of current: -10mA ~ +10mA (-2,000
