Control Register
CR# Attrib. Register name Explanation
#0 O R Model name
Set up by the system, model code:
DVP02DA-E2 = H’0041; DVP04DA-E2 =
H’0081
#1 O R Firmware version Display the current firmware version in hex.
#2 O R/W CH1 output mode setting
#3 O R/W CH2 output mode setting
#4 O R/W CH3 output mode setting
#5 O R/W CH4 output mode setting
Output mode: Default = H’0000.
Take CH1 for example:
Mode 0 (H’0000): Voltage output (r10V)
Mode 1 (H’0001): Current output
(0~+20mA)
Mode 2 (H’0002): Current output
(+4~+20mA)
Mode -1 (H’FFFF): All channels are
unavailable
#16 X R/W CH1 output signal value
#17 X
R/W CH2 output signal value
#18 X
R/W CH3 output signal value
#19 X
R/W CH4 output signal value
Voltage output range: K-32,000~K32,000.
Current output range: K0~K32,000.
Default: K0.
CR#18~CR#19 of DVP02DA-E2 are
reserved.
#28 O R/W Adjusted Offset value of CH1
#29 O R/W Adjusted Offset value of CH2
#30 O R/W Adjusted Offset value of CH3
#31 O R/W Adjusted Offset value of CH4
Set the adjusted Offset value of CH1 ~ CH4.
Default = K0
Definition of Offset:
The corresponding voltage (current) input
value when the digital output value = 0
