Facts and Changes

Reference: VW3A58101 V52IE27 (02)G0244, (01) G0241. We replaced one of them with an other display serial:G0003 and this display didn't have any problem. I downloaded the setting from ATV58 with powersuite, tbr=19200bauds. It means that baud rate of the RS485 serial link hasn't been changed. What could be the problem?

Causes and Fixes

This problem is in analysis and it concern the keypad EEPROM, it's a quality problem. For the moment the only solution is to replace the faulty keypad by 03 manufactured datecode.
