Digital PAD Setting Table for PA-24CCTA
As mentioned in General Function, this card is equipped with a mask ROM in which the following typical PAD
patterns have been already written. PAD value is determined by selecting a desired PAD pattern, which can be done
by key setting of the SW 12/58 (elements 4, 5, 6) on this card, and programming of the PAD data by the ARTD
command - PAD. The selected PAD pattern and the programmed ARTD PAD data correspond as listed below.
Note:
- represents “GAIN” in this table.
