CONNECTION
When the power supply is not connected, this instrument can be set with the thumbwheel switch on the front panel.
When this is done, set the INT/EXT selector switches to INT. When the BCD input or serial connection is required,
connect the power supply and short the CONT terminal. This instrument is selected and the SELECT lamp is turned on.
If the INT/EXT selector switch is set to INT, the thumbwheel switch will be selected, and if set to EXT, external setting
input (BCD IN) will take effect.
By connecting two or more of these units in series and operating the CONT terminal from an external unit, you can select
the required unit.
If the CONT terminal of the unit 2 is shorted in the figure below, the data set for 2 will be input. When this is done, if
the other units are shorted simultaneously, the data for the unit closest to the AD-4401 will be input.
The CONT terminal is configured as shown in the figure below. It should be driven so that the rated current will be 50
mA or more and the terminal voltage at ON time will be 1 V or less.
