The Assignment of I/O Address
The plug&play BIOS will assign the proper I/O address to PEX-1202/PCI-1202/1602/180x series card. If
there is only one PEX-1202/PCI-1202/1602/180x series card, the user can identify the board_0. If
there are two PEX-1202/PCI-1202/1602/180x series cards in the system, the user will be very difficult
to identify which board is board_0. The software driver can support 16 boards max. Therefore the
user can install 16 boards in one PC system.
The simplest way to find the board number is to use DEMO15.EXE given in DOS demo program
.
This demo program will send to D/O and read back from D/I. If the user installs a 20-pin flat cable
between CON1 and CON2, the value read from D/I will be the same as D/O. The operation steps are
given as follows:
1.
Remove all 20-pin flat cable between CON1 and CON2
2.
Install all PEX-1202/PCI-1202/1602/180x cards into the PC system
3.
Power-on and run DEMO15.EXE
4.
Now all D/I value will be different from D/O value
5.
Install a 20-pin flat cable into CON1 and CON2 of any PEX-1202/PCI-1202/1602/180x card
6.
There will be one card’ s D/I value = D/O value, the card number is also shown in screen
Therefore the user can find the card number very easy if he install a 20-pin flat cable into
PEX-1202/PCI-1202/1602/1800/1802 one-by-one.
