PCD7.D776 loses contrast settings!

This problem can be corrected through updating boot and firmware (PCD7.D776 Rev. 3) or by a hardware modification (PCD7.D776 Rev. 2). For updating the boot- and firmware version, please use the PCD8.D81W (VTWIN) version 5.18 (or newer) which can be optained from your local Saia-Burgess Controls AG sales office.
Procedure for resolving the problem on a PCD7.D776 Rev. 3
- Update the boot loader by using PCD8.D81W; function "TOOL" --> "BOOT UPDATE" à automatic, use the code 371013.
- Open the project, compile again and then re-download the project.
Procedure for resolving the problem on a PCD7.D776 Rev. 2
In this case the device needs to be returned to your local Saia-Burgess Controls AG sales office for applying a hardware modification.
Only in the programming tool version V 5.18 and newer, the new firmware and boot versions for the PCD7.D776 are included!
