Syncro Historic Firmware Support
Early versions of the Syncro multi loop control panel used an AMD microprocessor on their display card, to execute the main operating system program.
During 2004 the AMD microprocessor was replaced with a similar product manufactured by RDC, however it was necessary to make some small revisions to the firmware to allow the program to run properly on the new hardware.
The first firmware version that supported the RDC microprocessor was V4.00, released in April 2004.
The S550 display cards typically used on older Syncro panels did not have the Write Enable switch fitted and went up to firmware V4.61.
At this point, the Syncro product design was updated and approved to EN54-2 requirements. The display card was fitted with a memory write enable and a number of revisions were added to the panel operation so the firmware was updated to V5.xx to denote the major revision.
When replacing display cards on existing Syncro networks, it is important to ensure that all panels on the network have the same firmware version.
To help with this, it is possible to request for replacement / spare display cards to be pre-loaded with specific firmware versions to match the other panels on the network.
However due to the revisions added to the firmware to support the RDC microprocessor, it is not possible for us to supply S550 display cards with firmware versions lower than V4.00.
In such cases, there is no alternative but to upgrade the other panels on the network to V4.00 or later firmware.
If you encounter such a scenario, please contact Technical Support to discuss the best approach to ensure the system is upgraded without problems.
