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.)
