What's New

The Arbiter Systems, Inc. Remote GPS Receiver provides GPS synchronization for the Arbiter Systems' Model 933A (order number AS0077600) and the Doble Model F6150 (order number AS0077601) at the standard GPS frequency (L1 band) of 1575.42 MHz. Thus providing the best timing accuracy for the Model 933A and the Doble Model F6150. Although the remote GPS receiver is sealed against the weather, it is designed for temporary outside operation.

PSCSV version 1.114 (10 April 2008) is released for the Model 1133A.

• Updated copyright notice to 2008
• Wave data columns BV and BI were swapped with columns CV and CI when exported to PQDIF
• Saved phase data with freq configuration of 50Hz displayed as 60Hz when reloaded and displayed RS485 communication was noncommittal.

The Model 933A firmware updater is now release 0.0.3.0.

This release allows for use of serial ports greater than 9.

The 1133A Firmware Updater is now release 0.0.4.0.

This release allows for use of serial ports greater than 9.

The Model 1094B firmware uploader is now release 0.0.3.0.
The Model 1094B Utility Application is now release 0.3.0.

These releases allow for use of serial ports greater than 9.

The Arbiter Systems, Inc. Remote GPS Receiver provides GPS synchronization for the Arbiter Systems' Model 933A (order number AS0077600) and the Doble Model F6150 (order number AS0077601). Thus providing the best timing accuracy for the Model 933A and the Doble Model F6150.

The clock Model 1084A/B/C, Model 1088B, Model 1092A/B/C, Model 1093A/B/C, and Model 1094B manuals now have an appendix with a Statement of Compliance and a revised appendix covering options and CE marking. These manuals are now available for download.

The Model 931A manual was revised to fix an error in Figure 3-7, 3P3W2E transducer test. The L2 voltage connection was moved from N to B phase. It, too, is available for download.

The firmware since release v3.95 - 10May07 is not compatible with the original mainboard of the 1133A known affectionately as the 167 board. The newer mainboard is the 168 board and has been around for a very long time but there may still be demo 1133A's out there with the 167 board so be careful when updating the firmware.

Steps to determine Processor Type:
1. Download the Firmware Updater.
2. Run the Firmware Updater.
3. Click Tools.
4. Click Processor Type.
5. A window will pop up indicating the Processor Type.
6. If the Processor Type is 168 then you have the latest mainboard and the firmware and Firmware Updater are compatible.
7. If the Processor Type is 167 then you have an old mainboard and require an upgrade. Contact the factory for information.

The PMU Connection Tester application was developed by Tennessee Valley Authority (TVA) and verifies that the data stream from any known phasor measurement device is being received. It currently supports the following phasor data protocols: IEEE C37.118 Version 1/Draft 7, IEEE C37.118 Draft 6, IEEE 1344, BPA PDCstream and the Virginia Tech FNET streaming data protocol. Please read TVA's disclaimer.

The Models 1092A/B/C and 1093A/B/C now have 1 microsecond accuracy. Many of you remember that Option 91 was required to get 1 microsecond accuracy. This is no longer the case. Of course there is a small base price adjustment to reflect this change but these models are still a very good value for the price.
