Electrical Interface Selection via Software
When a 7802ec has been installed under Windows, the DIP switch Electrical Interface configuration can be
overridden by software settings via the SeaCOM PortManager.NET utility. Changing one port to be
overridden by software will automatically change the other port to also be software overridden. The initial
software override configuration of each port is adopted from its DIP switch configuration. All COM ports of
the 7802ec should be closed by applications when the software override option is changed in Port Settings.
RS-485 Auto-Enable Delay
RS-485 Auto-Enable Delay is an additional configuration setting available only via software selection. It
provides an ability to select a 0 to 15 bit-time delay that is inserted after the end of the last stop-bit of the
last transmitted character. This delay controls when to automatically disable the RS-485 transmitter. This
delay may be useful in long-cable networks.
