Help needed on FireWire(1394) data transmisson

NTDEV
1

Dear All,

I have two systems with 1394(firewire) ports on them. I am trying to
develop a lowlevel application to transfer the data between these system
using these ports. My application does not use any Operating System
services or drivers but it reads the 1394 OHCI register address in the PCI
configuration and uses the corresponding register for transmission.

Question:
How do I physically connect the two 1394 ports ? Do I need any additional
device ? or is there any cable (just like null-modem cable) to connect the
1394 ports?

please provide the details or suggest me where to buy it.

Any kind of information will be helpful.

Thanx in advance.

Regards,
Kedar.

You need a IEEE 1394 cable to connect two 1394 ports. (wouldnt be a problem
to get one…check with some local vendors…)

Write a program that will map the host controller Base address value (BAR0)
to
a structure (aligned as specified in the IEEE 1394 protocol specification).
(This works in DOS).
If you want to run it in windows take a look at the DDK sample, win1394.exe

Vijay Anand

Just use a simple 1394 cable.

1394 cabling is not oriented, so, use any 1394 cable.
