Digital PAD Setting Table for PA-24DTR (DTI)
As mentione d in Genera l Function, this card is equi pped with a mask R OM in which the follo wi ng typical PAD pat-
terns ha v e been already writte n. PAD va lue is determined by selec ting a desir ed 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 com-
mand - CDN=30( PAD). The PAD patter ns and ARTD data co rrespond as listed below.
Note: - represents GAIN in this table.
