Software Updates
Use the MMC/SD slot to update the software version of your control head. To update the software in your
control head, plug in the appropriate MMC/SD card that contains a software update file; the unit will
recognize it, will tell you what software version your control head is currently running, and will ask you if
you want to update the software in the unit to match that on the MMC/SD card. You can obtain software
updates from the www.humminbird.com web site.
Accessory Bus
Use the Accessory Bus to expand the functionality of your 1100 Series™.
Accessories plug directly into the 1100 Series™, enabling Advanced
features such as WeatherSense® and the CannonLink™ Downrigger
Controller. Additional tabs and menu choices will be added to the menu
system automatically when an accessory is plugged into the unit. In
addition, multiple accessories can be attached simultaneously. See
Accessories Menu Tab and 1100 Series™ Accessories in this manual,
as well as your accessory Operations Manual for additional details.
NOTE: Accessories such as the CannonLink™ Downrigger Controller, InterLink™, and WeatherSense® require
separate purchases. You can visit our web site at www.humminbird.com or contact our Customer Resource
Center at 1-800-633-1468 for additional details.
Video and GPS Output Connectors
Your unit has a built-in Video Out connector and a GPS Out connector, which can be used with optional-
purchase accessories. For instance, if you purchase a video monitor and attach it to your control head
using the Video Out connector, your unit will send a video signal if it detects a monitor. See Setup Main
Menu: Video Out for more information.
