New Serial Server firmware updates may become available through
the B&B Electronics website for installation into the server. The
firmware can be uploaded using either a virtual COM port connection
or hardware COM port connection.
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 Serial
Server.
Upgrading Via ESP Manager
The ESP Manager software can upload new firmware to the server
using a direct PC connection via the ESP901 serial port, ESP902 Port
1, or using a virtual COM port.

If connecting directly to a computer serial port, use a null modem
cable between the Computer RS-232 port and the ESP901 serial port
or ESP902 Port 1.
Preparing the Software
Step 1: In the ESP Manager 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 upload the firmware to the Serial
Server, set the baud rate to 115200 for the fastest possible
upload.
Step 3: Set the Serial Port field to upgrade and click the Update
button. (Ensure that the DIP switches on the ESP901 or
ESP902 are all in the OFF position.)
