-4DA (4-channel Analog Output)

For FX

3U

-4DA, the standard output characteristics are provided for each output mode (BFM #0)at the time of

factory shipment.
Changing the offset data (BFM #10 to #13) and gain data (BFM #14 to #17) can change the output
characteristics of each channel. This chapter describes how to change the output characteristics.

If setting change is prohibited, write K3030 in BFM #19. The setting change prohibition mode will
be canceled.

Determine the output mode (BFM #0) optimum for the selected channels and the voltage/current
specifications.

Example: Enter "HFF00" in BFM to set output mode 0 for channels 1 and 2 and prevent use chan-
nels 3 and 4 

• If a value "1" or "4" is set for a channel, the output characteristics of the channel cannot be changed.
• Set the optimum output mode for the analog signal to be output.
