BSD-ON: BSD 3.3 - ESS-IIT Communication
BSD-ON: BSD 16.1 - ESS
The NAK (Negative Acknowledgement) that notifies of the occurrence of a transmission failure
is received. (A parity error was detected by hardware of the UART.)
Procedure
• Ensure that the customer is programming a job within the parameters of the machine uti-
lizing the UI.
• Disconnect then reconnect the IIT, Control Panel, ESS, MCU all PWBs connected to them
(RAM, Firmware module, EEPROM)
• Reload Software (GP 16)
• Replace IIT PWB (Switch the EEPROM)
