Folks,

quadEM R6-0 is now available.

This is from the release notes:

************************************

- Added support for the CaenEls TetrAMM picoammeter. This device uses Gbit Ethernet without a built-in Ethernet to serial converter, so it is significantly faster than the AH501 and AH401 series. It supports on-board digital averaging. Note that TetrAMM firmware 2.0.09 or later is required because earlier versions have problems with the network stack.

- The base class and derived classes have changed somewhat to add this TetrAMM support, some of the database record names and types have changed, and changes are required to startup scripts. This is thus a new major release number. Some of the changes include

  - The Trigger record has been renamed to TriggerMode.

  - The TriggerMode record choices are now device-dependent.

  - The Firmware record changed from stringin to waveform to handle longer strings.

  - New records were added for the TetrAMM (BiasInterlock, HVSReadback, HVVReadback, HVIReadback, and Temperature).

- Added support for the NSLS electrometer from Peter Siddons. It is called NSLS_EM in this software. It is quite similar to the AH401B and APS electrometer, using a similar current integrator chip. It has a minimum integration time of 400 microseconds, and thus a maximum sample rate of 2500 Hz. It uses Ethernet communication, UDP to search for modules on the subnet and TCP to send commands and read data.

- The CurrentScaleN and ReadStatus.SCAN records were added to save/restore, they were previously missing.

- Added support for reading the AH401, AH501, and TetrAMM meters in ASCII mode, as well as the binary mode that was previously supported. Binary mode can occasionally get out of sync, because there are no terminators between readings. ASCII mode is slower, but should not have a problem getting out of sync. The new ReadFormat record is used to select Binary or ASCII.

- Template files in $(TOP)/quadEMApp/Db are now installed into $(TOP)/db when building and the example IOC now loads them from the install directory.

- The device-specific template files now load the base class quadEM.template file using an "include" statement, so the base file no longer needs to be explicitly loaded in the startup script. This means that $(QUADEM)/db must be added to EPICS_DB_INCLUDE_PATH.

- This release requires areaDetector ADCore R2-4 or later.
