Main Board Update History

Ver: 1.20.004 February 15, 2013

Improved scale step feature to allow real-time DIO off for fast weight done, slow starting.

Ver: 1.20.003 August 7, 2012

Resolved issue that with OIML enabled and using ICAN COM3 OIML weight output was not working.

Ver: 1.20.002 July 18, 2012

Updated to raise OPI CTS during first character transmission of message to OPI board when multi drop mode is disabled. Updated OPI will use this to verify message sychronization when multi drop mode is disabled. Disabling multi drop mode seems to prevent problem with MCF5213 UART sometimes going into non- recoverable repeating transmission of data. Updated scale step mode to allow for digital output to be turned off when slow fill is finished.

Ver: 1.17 September 1, 2010

Improved COM3 to allow TX enable/disable for RS485. Uses same command from main board as SetRTS.

Ver: 1.16 February 17, 2010

Added support for ICAN cards.

Ver: 1.14 July 9, 2009

Added support for DIO card counting feature.

Ver: 1.12 June 17, 2009

Added support for DAC card.

Ver: 1.11 March 3, 2009

Communications improvements to help prevent “Lost communications with main board”.

Ver: 1.10 November 7, 2008

Added DIO event method to remove all events and reset outputs to low state. 5B {card} 00 00 00 00 FF FF FF FF {condition empty}

Ver: 1.08 Oct 15, 2008

Fixed problem if main board received message from OPI of 2 bytes or less, which might happen due to noise, the main board would stop communicating with the OPI causing “Lost communications with main board”.
