Installation Guide
PC Elite Reference
Using More Than One PC ELITE IEEE Board.
_________________________________________
Since each PC ELITE IEEE card can control up to 14
separate IEEE devices it is not generally necessary to have more
than one PC ELITE IEEE board installed in the PC at any one
time. However, it is possible to control multiple IEEE buses
from one PC with several PC ELITE IEEE cards.
The golden rules to follow to allow this are:-
i.)
Ensure that each PC ELITE IEEE card is set to a different
i/o address.
ii.)
If you are using the Professional 488 Device Driver then
ensure that the each PC ELITE IEEE card has its own
driver software installed and that the file name associated
with each IEEE port is different.
Professional 488 device Driver requires that the
CONFIG.SYS file must have an DEVICE= PRO488.SYS
statement included for each PC ELITE IEEE card in use. Each
statement must give the individual card i/o address and file
name. E.g. A PC with three PC ELITE IEEE cards controlling
three separate IEEE 488 buses of up to 14 devices each might
have the following CONFIG.SYS file.
DEVICE=PRO488.SYS
DEVICE=PRO488.SYS /"IEEE2 ","IEEEDAT2","IEEECTR2",@22E1h
DEVICE=PRO488.SYS /"COM1 ","IEEEDAT3","IEEECTR3",@42E1h
In this case the first time PRO488.SYS is loaded it creates
a device driver which accesses a PC ELITE IEEE card at i/o
address 02E1h with filename IEEE, the data filename is
’IEEEDATA’ and the control filename is ’IEEECTRL’.
The second time PRO488.SYS is loaded it creates a device
driver which accesses a PC ELITE IEEE card at i/o address
22E1h with filename IEEE2, the data filename is ’IEEEDAT2’
and the control filename is ’IEEECTR2’. The third time
PRO488.SYS is loaded it creates a device driver which accesses
a PC ELITE IEEE card at i/o address 42E1h with filename
COM1, the data filename is ’IEEEDAT3’ and the control
filename is ’IEEECTR3’.
