Chapter 8: UPGRADING THE ESP904

FIRMWARE

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 ESP904 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.

Note:

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 on 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 115.2k for the fastest possible upload.

Step 3: Set the Console Mode field to upgrade and click on the Update button.

Step 4: Click Yes on the vcomui window to restart the ESP904.

Upgrading the Firmware

Step 5: Double-click on the Firmware Upgrade icon (or click on the Server menu and Firmware Upgrade)

Step 6: In the Upgrade window, select Browse. The Open dialogue box will appear. Locate the folder that contains the firmware .hex file. Select the file and click Open. The Open dialogue box will disappear.

Step 7: In the Upgrade window select the serial port to be used in transferring the firmware.

a.If connected directly from the computer to Port 1 of the ESP904 the port will typically be COM1 or COM2

b.If using a virtual COM port to upgrade via the network, identify the virtual COM number and address mapped to Port 1 on the ESP904.

Step 8: Click on Upgrade

Step 9: In the Port Settings window set the Bits per second, Data bits, Parity and Stop bits to the same values as set up in the Server Properties window. Click OK.
