Installation

STEP 4. Connect Hardware

Multiple Input Devices

You can select multiple COM ports for input, for example, a GPS to COM Port 1
and an AIS Transceiver device to COM Port 2. If you connect two devices which
supply the same type of data, such as two GPS units, you must set up port priorities
to tell the program how to handle multiple sets of similar data, or manually set up
your NMEA devices using the GPS/Port Setup Wizard.

TIP:

If your computer does not have serial ports, Jeppesen Marine

recommends that you use SeaLevel

Serial-to-USB port adapters to connect

these devices.

Wiring a GPS to Your Computer

GPS Settings

Many GPS devices must be specifically configured to output data. Check your GPS
Installer’s Guide to determine if your GPS is configured to transmit NMEA data, and
follow the instructions to turn on NMEA output.

NOTE:

These settings assume that the GPS will output information in the

WGS84 Datum.

NOTE:

If your NMEA device uses an RS-422 connection standard, consult your

device manufacturer for wiring instructions, or contact Jeppesen Marine for
an RS-422 interface device. If your device wiring pins are labeled "Transmit/
Receive +" or "Transmit/Receive -", it is most likely RS-422 standard.

Cables

Use a standard 9-pin “D” connector (DB9) data cable to connect the GPS to your
computer. You will also need a connector cable. If you did not receive one with your
GPS originally, purchase one from your GPS retailer or manufacturer.
