(1)Address map
D The memory space is identical to that of IBM PC–compatible
personal computers. There is no special area used by Series 210i.
D In the I/O space, addresses 280H to 28FH are used by the Series
210i, such that they are not available for the ISA expansion boards.
(These addresses can be changed, however. They can be set with
a rotary switch on the PC interface connector panel unit.)
Other areas in the I/O space are identical to an IBM PC–compatible
personal computer.
SW3 SW2 SW1
(L) (M) (N)
The I/O addresses of Series 210i are:
LMN0H to LMNFH.
L, M and N are set as shown below
when the unit is shipped from FANUC.
L = 0 (SW3)
M = 2 (SW2)
N = 8 (SW1)
(2)Interrupt, DMA request
D Of the IRQ signals, the following are not used by the Series 210i.
IRQ10, IRQ11
D Of the DRQ signals, the following is used by the Series 210i.
DRQ2: Floppy disk drive.
(3)Installation and environmental conditions for ISA expansion boards
See Section 3.1. If, however, the specifications of the ISA expansion
boards are inferior to those listed in Section 3.1, these conditions are
restricted by those of the ISA expansion boards.
(4)Power supply to ISA expansion boards
The table below indicates the ratings of the power supply that can be
fed to the ISA expansion boards mounted on the ISA expansion unit.
(The total values for two slots are indicated.)
Voltage Rating
+5V10% 3.0 A maximum
+12V10% 0.5 A maximum
–12V10% 0.1 A maximum
–5V10% 0.05 A maximum
(5)Other
In addition to the cautions given above, normal operation may be
impossible under any of the following conditions.
D When pull–up or pull–down processing has been applied to the ISA
bus signals.
D When the refresh cycle of the ISA bus is in use.
In addition to the above, note that further conditions may be added
in the future.
