Updating the Firmware
You can update the firmware on the MBCN using either of two methods:
• using ControlFlash over ControlNet. In order to use this method, the
MBCN must be running firmware version 1.10 or above. If the
firmware version is an earlier one, you must first upgrade the
firmware using the serial port, after which you can use ControlFlash
for the updates
• using the serial port on the MBCN
The usual method is to use ControlFlash.
ControlFlash
Follow the procedure in the ControlFlash documentation to update the
MBCN firmware. The MBCN firmware version must be 1.10 or above
to use ControlFlash.
While the firmware is being updated, the LED on the MBCN displays
‘U’. While the hardware on the MBCN is being updated, the LED
displays ‘H’
NOTE: ControlFlash indicates an error when the download is complete.
This is normal and occurs because the MBCN cannot reset itself.
When the download is complete, the LED on the MBCN shows ‘r’,
indicating that the MBCN requires reset. Cycle power to the rack that
contains the MBCN. Do NOT cycle power until the ‘r’ appears on the
LED.
Serial Port
The following procedure describes the steps necessary to download a
new version of the MBCN software into flash memory on the MBCN.
DO NOT CYCLE POWER TO THE MODULE DURING FIRMWARE
DOWNLOAD.
The serial cable for a standard PC COM port must have lines 2 and 3
swapped. It doesn’t require any handshaking. Pins 2 and 3 are wired the
same as a PC 9-pin COM port.
