The example IOC can be built outside of driver module. + +The 874x controller requires firmware v2.3 for units produced prior to early 2017. For units after early 2017, the driver works with firmware v4.06. The v2.2 is missing commands (SR/SL) used by the EPICS driver. +In early 2017, firmware v4.06 was released. This was due to a revision in MCU/processors in which the whole MCU/processor changed. Controllers with the newer processing unit cannot be upgraded from 2.x to 4.x. However, older units with v2.2 should be able to be upgraded to v2.3. \ No newline at end of file
