8 Upgrade Mode
New DSE-410D firmware may become available through our Web site for installation
into the DSE-410D. The software can be downloaded to the DSE-410D using either
the Virtual COM or hardware COM port.
Using Virtual COM or Serial Connections
1. Make a folder to receive the firmware file. Download the compressed
software file from our website to your folder. Unzip or expand the file into
the (.hex) format so it will be ready to download to the DSE-410D.
2. Before Setting the DSE-410D to Upgrade mode, we recommend setting the
DSE-410D Server baud rate to 115.2K if using a hardware COM port. This
will provide the fastest download.
3. Set DSE-410D Dip Switches to Upgrade, Switch 1 - OFF, Switch 2 - ON,
and Switch 3 - ON. (As shown here)
4. If using a Virtual COM port to upgrade, identify the virtual COM number
and address used for the Multi-Interface port.
5. If connecting directly to a Computer serial port, connect a null modem cable
(Appendix B) between the Computer RS-232 port and the DSE-410D Multi-
Interface (DSE-410D Port 1) serial port.
