by Hi, this question is not Linux hardware specific, but perhaps this group
could help.
We have recently purchased a HP E8491A firewire to VXI controller,
which links a PC via firewire (IEEE1394) to a VXI crate.
PC VXI rack
+------+

|Linux | --- IEEE1394 ----> |HP E8491A ---> Tek
TVS621 |
+------+ | ---> Device

+---------------------------------------------+
We would like to control the VXI rack with the PC running Linux
(currently RedHat 6.0, kernel 2.2.11).
The Linux firewire interface works fine (thanks Emanuel Pirker +
others).
However, we donot know the HP protocols for controlling the
VXI rack, eg. selecting devices within the rack.
The software supplied with the HP device runs only under win95/NT.
It uses a standard interface control library (SICL), with commands
like:
dev_controller = iopen ("vxi");
dev_1 = iopen ("vxi",24);
other commands are then device specific eg.
iprint (dev_2,"RESET\n");
Does anyone have any ideas as to what character strings need to be
sent down the firewire cable to cause the HP controller to select
a device in the VXI rack?
Thanks for any help,
Steve.
