PAC Control: Some 32 Bits Commands Don't Copy Bit for Bit


Applies To:

Firmware for:

  • SNAP-PAC-S1, SNAP-PAC-S1-FM, SNAP-PAC-S1-W
  • SNAP-PAC-S2, SNAP-PAC-S2-W
  • SNAP-PAC-R1, SNAP-PAC-R1-FM, SNAP-PAC-R1-W, SNAP-PAC-R1-B
  • SNAP-PAC-R2, SNAP-PAC-R2-FM, SNAP-PAC-R2-W
  • SoftPAC

Versions Affected:

Version R9.4a to R10.4b

Resolved In Version:

R10.4c


Symptoms:

The following PAC Control commands should move values between a 32-bit integer and 32-bit float, bit for bit, so if you move an integer to a float and back, the value of the integer should be unchanged:

  • Float to Int32 Bits
  • Int32 to Float Bits
  • Move 32 Bits
With this issue, the value of the integer may be changed.

Resolution:

Opto 22 has resolved this issue.
