Micronet Touchscreen error


Updated June 2019

The MicroNet 50 series range MN350, 450, 550, 650 LCD and Touchscreen have been withdrawn from sale.
The IAC 420, 600 and Touchscreen have now also been withdrawn from sale.
No direct replacement is offered.
Further information on these changes can be found in PA-00495 - Notice of Withdrawal - Satchwell Sigma and PA-00528 - End of Commercialization - Satchwell Sigma.


The problem generally occurs when there is heavy communication traffic through the Touchscreens.

New Touchscreen firmware version MNTS0H has been released fixing this issue.

The firmware has been tested with VisiSat 2.1 Build 148 Service pack 1, MN50 series controllers, Xenta 555 and Xenta 731 hardware.

Please refer to TPA-LOND-09-0029.00 Touchscreen TS0H firmware.
