message-based devices, you can send and receive messages with the

wsrd()
functions. Notice that
vxiinReg()
and
vxioutReg()
are for VXI devices only.
What should I do if I get a
Configuration EEPROM is Invalid
message?
There are several reasons why you could receive this message. If you turn
off the computer while the configuration update process is still in progress,
the VXIpc functions normally except when using vxitedit. To correct
this problem, switch to the factory configuration as described in the
configuration and installation chapter of your VXIpc user manual. This
requires that you change switch S9 on the VXIpc 800 Series or jumper W7
on the VXIpc 700 Series. Reboot the computer and update the
configuration, or load the configuration from file.
Two other reasons you might receive this error message are that the board
might have an incorrect base address assigned for the driver window, or the
memory for the MITE’s configuration EEPROM may not be mapped
correctly. If a mapping error is the cause, follow the instructions in the
Step 3. Set up the VXIpc Controller with VxWorks
section in Chapter 2,
, to set up the mapping in
sysLib.c
.
What do the LEDs on the front of the VXIpc controller mean?
Refer to the LED indicator descriptions in your VXIpc user manual for a
description of the front panel LEDs.
Is something wrong if the red SYSFAIL and FAILED LEDs stay lit
after booting the VXIpc controller?
If either the SYSFAIL or FAILED LED remains lit, refer to the LED
indicators descriptions in your VXIpc user manual for troubleshooting
steps.
Can I access 32-bit registers in my VXIbus system from the VXIpc?
Yes. The VXIpc uses the 32-bit PCI bus to interface to the VXIbus. In fact,
its VXIbus circuitry also supports the new VME64 standard for D64
accesses.
What kind of signal is CLK10 and what kind of signal do I need for an
external CLK10?
CLK10 is a differential ECL signal on the backplane. However, the
oscillator for the VXIpc 800/700 and the EXTCLK input on the VXIpc 800
