1 Introduction
Thank you for purchasing the Navigator Sound Card Modem. The Navigator is a full featured, multi-mode digital interface between
your PC and your amateur radio transceiver.
In this manual, you will find information about the features of Navigator, the design architecture, hardware and software installation
and the technical specifications of the device.
The appendix of this document contains technical specifications of I/O signals, Frequently Asked Questions (FAQ) about installation
& operation, and the Navigator Software Distribution CD-ROM
The Navigator CD-ROM provided contains a section “Docs” which has detailed procedures for installing Navigator with your USB
enabled PC.

2 Architecture
2.1 The Navigator is a general purpose, sound card modem & rig controller with precise CW and FSK operation that connects an
Amateur Radio Transceiver to a Personal Computer. Connection to the PC is by a single USB cable. The Navigator provides all
audio and control functions required for sound card modes with precise FSK, CW and rig control. A block diagram of the Navigator
is shown below.
All USB devices are controlled through an internal 4 channel USB Hub controller. Full two channel audio is provided by a USB
audio codec. Three dual USB UART devices provide 6 USB COM ports. These COM ports are assigned to interface functions to
provide compatibility with existing software applications. The assignments are detailed in the table on the following page.

Navigator Hub Assignments
Hub channel 1
USB Audio Codec
Hub channel 2
COM port A - Rig CAT Control
COM port B - PTT/CW control & DCD input
Hub channel 3
COM port A - WinKeyer V22 CW Controller
COM port B – RTTY/ FSK Controller
Hub channel 4
COM port A - Auxiliary RS232 DCE port
COM port B - Navigator Options Controller
Interface Options are software selectable – no jumpers are used on the interface board.
An audio monitor is provided within the interface so that you can hear the side tone of all audio generated modes such as PSK. Side
tone monitor of the WinKeyer CW controller and the FSK Controller are also provided.
Navigator is designed for use with Personal Computers using the Microsoft XP and Vista operating systems.
Navigator is an FCC class B certified USB computer peripheral device. It is also RoHS, European CE and Industry Canada
compliant.
2.1.1 USB Device Serial Numbers
Each Navigator is assigned the same serial number set for the COM ports attached to the Hub. This allows easy installation of
Navigators if replaced under warranty, or if several Navigators are purchased for a collection of different computer systems.
2.1.2 Multiple Interfaces on One Computer

8
If multiple Navigators are installed on a single computer, Windows uses the USB channel as part of the address to identify each
Navigator uniquely. This allows multiple copies of the operating software to be running simultaneously, each talking to it’s own
Navigator. This requires that each software instance “belongs” to its own directory/folder within the computer.
Each instance can be operating the same type, or different types of transceivers. If you plan on multiple Navigators operating on one
computer, ask us to change the USB serial numbers of the additional interfaces.
Note that if a dual receiver transceiver such as the Icom 7800 or the Yaesu 1000D is connected, only one instance of the operating
software is required, since the interface has two input channels, one for each receiver.
2.2 USB Hub
- Bus Powered
-Total current for Hub and all Interface devices is less than 160 ma.
-Current draw during Hub enumeration less than 30 ma.
-Soft power control of VBUS for downstream devices
-Removes VBUS when in suspend
-Power LED activated after Hub is enumerated and VBUS is applied
-CW and PTT controls are disabled for 10 seconds during device startup.
Power LED shows Orange during setup and Green after setup.
2.3 Audio Functions
