Note
When both a BCD board and an RS-232C board are installed, if the BCD DRQ signal and
the RS-232C EXT.IN signal are input at the same time, the BCD DRQ signal is ignored.
SIGN output
Tells whether the output data is positive or negative.
With positive logic OFF is "–", and ON is "+".
Alarm output
This is set to OFF when an alarm is triggered for any channel. (This is the same function as
the alarm output of the display unit.) Remove the cause of the trouble, and then set to ON
by switching the display to show the counter board in question and pressing the reset key
or by inputting the reset signal to the I/O connector.
Note
• After the DRQ signal goes ON, the main display is locked to the status just before the
DRQ signal went ON until the READY signal (during all channel output, the READY
signal with respect to the last SET signal) goes OFF. In addition, front panel key
operations are also not accepted during this period.
• When the initial setting of counter board I/O connector pins 2!§ is
judgment (I/O connector output, front panel LED) is held from the time the DRQ signal
goes ON until the DRQ signal (the last SET signal during all channel output) goes OFF.
