Re: Motor Record - OMS58 Driver

Ralph,

There may be a problem in your st.cmd file where the VME58 address is.
The device support changed between these versions such that each
omsSetup line that you have should now be combined into 1 line.

So instead of having:
omsSetup(1, 8, 0xFC00, 180, 5, 10)
omsSetup(2, 8, 0xFC10, 180, 5, 10)
omsSetup(3, 8, 0xFC20, 180, 5, 10)

You would now just have:
omsSetup(3, 8, 0xFC00, 180, 5, 10)

The card number is now the number of cards and the address is
just the starting address of the first card. Subsequent cards
need to be addressed so that they are 10 addresses away from
the previous card. I can't remember in which version of the motor
record this got changed in but I'm pretty sure it is in some
release note somewhere.

Hope this helps.
Marty
