SECTION 5 - MICROBOARD 031-03630-001

FORM 160.54-M1

ISSUE DATE: 10/25/2019

JOHNSON CONTROLS JCI COMPANY CONFIDENTIAL

At the completion of the re-programming pro-

cess, if it is successful, “Flash Has Been Success-

fully Programmed” is displayed and “Operation

Successful” is displayed in the Status Code box.

Otherwise, a message in the status box indicates

the step that failed.

8. Remove power from OptiView Control Center.

9. Remove Program card from Microboard connec-

tor J26 by lightly pushing the SD card in and then

releasing pressure. The SD card should pop out

slightly allowing for removal.

10. Reposition Microboard DIP Switch SW1 position

4 to OFF.

11. Apply power to the OptiView Control Center. The

re-programming procedure is now complete.
