The Seres smart antenna features reverse polarity protection to prevent
damage if the power leads are accidentally reversed.
A 1.0 A fast-blow fuse, situated in-line of the power input of the extension
cable and protects the Seres receiver from power surges. The fuse
container should remain accessible after installation.
Once the Seres system has been installed, you’re ready to turn the system
on by applying power to it. The Seres smart antenna will start when and
acceptable voltage is applied to the power leads of the extension cable. Be
careful not to provide a voltage higher than the input range as this will
damage the antenna.
Caution - Do not operate the Seres with the fuse bypassed. Such
a modification will void the product warranty.
2.6.5 Connecting the Seres To External Devices
The dual serial ports of the Seres are compatible with the RS-232C
interface level to communicate with external data loggers, navigation
systems, and other devices. These serial ports are accessible via the
extension cable that features two DB9 female data connectors labeled ‘Port
A’ and ‘Port B’.
You may use either the A or B port for operation of the system, however
Port A should be used for firmware updates. Either port may be used for
the input of external differential corrections, if desired.
The following two tables provide the pin assignments for both ports.
