1. Add support for C37.118 CFG-2 messages to be sent via the UDP broadcast port.
2. Updated how the C37.118 auto UDP start-up functions. The broadcast will no longer be enabled all the time (it can be stopped via the C37.118 stop broadcast command).
3. Relays put into fault state when hardware fault detected.
4. Requires PSCSV v1.128 or newer

1. DNP Update: Add Class-1 response. Note: Will only respond if a subset of Class-0 data is selected.

1. DNP Update: Add "selectable" Class-0 response.
2. Update Flash power-up detection to work with new flash memory chip.

1. Updated DNP to correctly respond to unimplemented functions.

1. Updated to correctly respond to unsupported Object-30 qualifiers
2. DSP: Restore DNP frequency scaling to 0.01Hz and to a signed value

1. Add support for new redesigned 32 MB data Flash memory card.

1. Remove TCP selective ACK feature. It behaves erratically when TCP port is closed in the middle of a retry sequence.
2. Fix scheduled data download problem (lock-up on version 4.00)

1. Add Power Factor and Q analog values to C37.118 message
2. Add new "Ghost" PMU feature (PMU-3)
3. Now using BSD TCP keepalive feature.(no more 10min timeout)

7. Update front panel event time to display asterisk when time not set
8. Requires PSCSV version 1.105 or greater.

1. Fix event input lock-up problem.
2. DSP: Activated 0.14 degree phase offset correction. The NIST results indicate an offset of -0.14 degrees and a slight negative slope with frequency.

1. NOTE: The firmware for the "167" boards is no longer included in the firmware releases. The Model 1133A serial number must be 94 or greater to use this firmware.
2. DSP: Fix missing x.083333 PMU phasor record when using 60 times/second rate.

1. NOTE: This is the last release for the "167" boards. See "Steps to determine Processor Type:" on the firmware page
2. Fix potential lock-up problem associated with PSCSV TCP connection time-out.
3. Enable TCP selective ACK feature
4. Ethernet driver update (fix re-transmit)
5. Download Firmware File

1. Fix DSP version date (No code change)

1. (DSP) Fix potential dependent trigger mode problem
2. Fix C37.118 Digital Status words (DIGUNIT) for CFG-1 CFG-2 configuration frames. It had Normal Status and Active Mask values reversed.
3. Ethernet: Correct potential broadcast/ARP input message parsing problem

1. Ethernet: Fix intermittent transmit problem
2. Fix IRIG-B 90ms position identifier P1 (was 2ms instead of required 8ms)

6. Fix current display for values greater than 10,000.0A.
7. C37.118 Updates:
   1. No longer supports a UDP "connection" mode. The UDP is now only used to broadcast the C37.118 data.
   2. Correct problem of not properly processing multi TCP C37.118 commands contained in one TCP message.
   3. Fix PMU-2 TCP reconnect problem.
   4. Fix problem associated with changes to the PMU Ethernet configuration not "seeming" to take effect unless the unit is re-booted.
   5. Fix C37.118 STAT bit 13 (Sync) bit function
   6. Add autonomous mode to C37.118 UDP broadcast, Unicast and Multicast.

1. Fix trigger log data type retention problem (Waveform, PMU-1 and PMU-2 types reset back to "None" when unit reset).
2. Add power-up initialization of Trimble GPS navigation configuration.

1. Fix C37.118 problem related to data records incorrectly being time tagged one second ahead of time.
2. Disable Multicast reception and strip off all broadcast messages, except ARP, before it takes up an Ethernet processing buffer.

1. Fixed potential lock-up problem associated with backed up C37.118 not being pulled off fast enough by the host.
2. Fixed Raised-Cosine algorithm and simplified Kaiser window algorithm
3. Adaptive tuning now works for ±2, ±5 and ±10 Hz.

1. Fix PMU power-up initialization problem.
2. Fix potential TCP task prority re-assignment problem associated with the TCP ports used for C37.118 (PMU-1 and PMU-2).
3. Change the PMU default values to something more sensible.

1. Fix serial port (1 and 2) overflow problem associated when too much data selected for broadcast.
2. Fix DSP problem associated with using the PMU "Raised Cosine" option. (After power-up, all phasor data would remain 0's until the PMU was re-initialized)

1. Fix PMU-1/PMU-2 event logging (was not storing correct data).
2. Clear PMU message count word to indicate to DSP that PMU message area is ready for next message.
3. Use the DSP trigger information to "fill-out" C37.118 trigger info in the STAT word (STAT Bit 11 and Bits 03-00).

1. Replace IEEE-1344 with C37.118 standard. For legacy sake, the ASI 1344 broadcast functionality was kept.
2. Fix C37.118 Seconds Of Centry (SOC) calculation (C37.118 starts 1970 while it still had 1344's version which starts 1900).
3. The phasor measurement time-tag assignment was inadvertently left off of PMU-1 and PMU-2 trigger logging record.
4. Fix intermittent LCD-keyboard "lock-up". Problem had to do with LCD time-out which in turn disables any more updates to the LCD.

1. Enable time range erase for Flash event area.
2. (DSP) Fix sequence demand logging

1. Add sequence voltage elements to scheduled data logging.
2. Add Flicker calculation constants selection (50 or 60 Hz).

1. Requires PSCSV version 1.024 or greater.
2. Download any information from the 1133A memory you want to keep.
3. Upload the new firmware.
4. Format the memory using PSCSV.
5. You are now good to go.

1. Add 10 minute time-out to ethernet connections (close TCP port after 10 minutes of inaction).
2. Add ethernet status message and message to kill specified TCP port.
3. Add place holders for the new C37.118 phasor TCP and UDP connections.
4. Clean-up "auto" variables (make sure to limit size for task use).
5. Add Vh, V2h, Ah and A2h calculation for logged V-I schedule data for 3-Phase3W2E mode (Peru).

1. Fix problem with scheduled K-factor calculation (DSP processor)

1. Fix channel-B scaling in 2 element mode (DSP processor)

1. Updated the version status screen to only show one version number.
2. Fix CT/PT scaling problem caused when switching over to common structures/directories.

1. Updated to use new "shared" directories (host-dsp-pscsv).
2. Fix Seconds-Of-Century calculation in "time.c". Was incorrectly adding in leap years one year AHEAD of time.

1. Add zero, positive and negative sequence readings to the IEEE-1344 phasor message.
2. DSP trigger word (32-bit) was also added to the phasor message

1. Update the IEEE-1344 configuration frame to include the CT and PT nominal ratios.
2. Add Vorne's display capability for both serial ports (configurable).
3. Update ethernet code to try to detect and recover from a locked interrupt.
4. Separate checks of the DSP configuration elements so that one element will not initialize the others.

1. Updated the Energy front panel display to use Register data values instead of demand data.

1. Loader is now linked in with host firmware and no longer loaded via the PC.
