New ESP904 firmware updates may become available through the B&B
Electronics website for installation into the ESP904. The firmware can be
uploaded to the ESP904 using either a virtual COM port connection or
hardware COM port connection to ESP904 serial port 1.
Downloading the Firmware
Make a folder to receive the firmware file. Download the compressed
software file from the B&B Electronics website. Unzip or expand the file
into the (.hex) format so it will be ready to upload to the ESP904.
Upgrading Via ESP Manager
The ESP Manager software can upload new firmware to the server using a
direct PC connection via Port 1 of the ESP904, or using a virtual COM port
mapped to Port 1.

If connecting directly to a computer serial port, connect a null modem cable
between the Computer RS-232 port and the ESP904 Port1 serial port.
Preparing the Software
Step 1:
From the ESP Manager, in the
Serial Server List
window, double
click the server to be upgraded. The
Server Properties
window will
appear.
Step 2:
If using a direct connection to serial port 1 to upload the firmware to
the ESP904, set the baud rate to
115200
for the fastest possible
upload.
Step 3:
Set the
Serial Port Mode
field to upgrade and click the
Update
button.
Step 4:
Click
Yes
on the
vcomui
dialogue to restart the ESP904.
