7.4.2 Dump Function
When the dump button on the System Settings Screen is pressed the
console assumes the role of the master of the serial bus. A DB9 male-
to-male null modem cable (3 pin RS-232cable) should be used to
connect the two consoles. Cross pins 2 and 3 on the cable and connect
pin 5 straight through. The master attempts to establish communication
with a slave console and begin downloading the contents of the EEPROM resident on the master console. Upon
successful connection to a slave console, the status line will appear on the screen. When the download is complete,
the Master screen returns to the System Settings Screen. If the proper acknowledgments are not received the
transmission stops and the Dump Error Screen is displayed.
7.4.2.1 Dump Error Screen
This screen is displayed because an attempt to perform a memory dump was ended unsuccessfully for some reason.
This stays up until the memory dump is aborted by pressing the “back” button or is attempted again by pressing the
“Dump” button. When the dump is attempted again the display returns to the Dump Screen.
PROG3 - Attempt memory dump again.
PROG4 - Return to System Settings Screen.
