Control Register
CR# Attrib. Register name Explanation
#0 O R Model name
Set up by the system:
DVP04AD-E2 model code = H’0080
#1 O R Firmware version Display the current firmware version in hex.
#2 O R/W CH1 input mode setting
#3 O R/W CH2 input mode setting
#4 O R/W CH3 input mode setting
#5 O R/W CH4 input mode setting
Input mode: Default = H’0000.
Take CH1 for example:
Mode 0 (H’0000): Voltage input (±10V)
Mode 1 (H’0001): Voltage input (±5V)
Mode 2 (H’0002): Voltage input (0 ~ +10V)
Mode 3 (H’0003): Voltage input (0 ~ +5V)
Mode 4 (H’0004): Current input (±20mA)
Mode 5 (H’0005): Current input (0 ~ +20mA)
Mode 6 (H’0006): Current input (+4~ +20mA)
Mode -1 (H’FFFF): Channel 1 unavailable
