Step 6: Replace the system cover.
Note ! Each board must occupy one unique IRQ and one
unique memory address, which are assigned by PCI
BIOS automatically. However, you may select the free
IRQ number manually via PC’s BIOS setup for PCI slot,
but this method is not available for memory. The possible
IRQ numbers are 2(or 9), 3, 4, 5, 7, 10, 11, 12, and 15.
Now the installation of the Control Board is complete. Continue to install
the external modules.
Installing the External Modules
There are two major connection options for the installation of external modules:
CPU and UART Modules for Desktop option or Basic and Extensive Modules for
Rackmount option.
Normally, a standard 2-meter DB25 to DB25 cable with 25 signal pins links the
Control Board to the external module. However, to extend the distance between
Control Board and external module to above 2 m and up to 100 m (328 ft) or to
improve power insufficiency problem of the PC host, external power for the
CPU/Basic Modules along with a cable specially fabricated with only 10 signal
pins should be used as illustrated in the next two subsections and in chapter 5 as well.
Otherwise, power degradation which comes from longer cable or power insufficiency
of PC host will cause system failure.
Installing the CPU and UART Modules (Desktop)
Step 7: Connect the Intellio C320Turbo/PCI Control Board to the CPU Module
with the shipped DB25 to DB25 cable as shown in the following picture.
If range extension or external power is required, please use 10-signal-pin
cable coming with long range extension kit, instead. Thus, there are two
types of installation: without power adapter and with power adapter,
which are described as follows:
