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.
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.
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.
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.

2.3.2 Interface - 2 Channel Analog Input Channels - Two input channels - Transformer Isolated, analog ground isolated from digital ground - 10,000 ohm audio transformer each channel - Level controlled by front panel potentiometer, each channel - Software settable input attenuation 0 dB and 15 dB each channel - Dual receiver transceivers are supported, each receiver with its own input channel 2.3.3 Interface - Analog interface –...
Half duplex TTL level high true – two wire, open collector transistor drive. TTL receive. Icom C-IV compatible. A 3.5 mm (1/8 inch) connector is provided at the rear of the Navigator as an auxiliary output for C-IV applications. The C-IV signal provided for the transceiver under control of the Navigator is provided on the DB25S connector.
2.4.3 Rig Interface Control Signals All rig interface signals are available on a DB25S connector on the back of the interface. Output control signals include PTT, CW, and FSK. These are all open collector transistor outputs. Input signals include the SQUELCH input to the PTT/CW UART, which is connected to the DCD, DSR and CTS pins for use with applications such as that need to know when the rig Squelch has been activated.
Setup and test of the WinKeyer is done via WK2MGR software provided by K1EL. A COM port is dedicated to operation of the keyer. You can plug your paddle into the Navigator, and provide keyed output either from the keyboard or from the paddle.

A general purpose RS232 Interface is provided on one COM channel of the Navigator. This is implemented as a DCE device (just like the one on the back of a computer). Signal levels are bipolar RS232, generated by MAX232 integrated circuits. Signals...
CW – Yellow LED, ON whenever CW is being sent to the transceiver from the Navigator. PWR – Two Color LED to indicate the state of interface power. When power is first applied to the Navigator, the HUB is enumerated. The PWR LED will be off. Then, after Hub Enumeration is done, power is applied to the rest of the board. For the first 10 seconds, the PWR LED is set to Orange (Green plus Red).
4 Rear Panel Connector Navigator Rear Panel The rear panel layout is shown above. See Appendix A for full description of the signals on these connectors. General Purpose RS232 DB9P mates with DB9S on the cable. Transceiver DB25S, mates with DB25P on the cable. Signals on this connector connect to the transceiver.
Recommended wiring for your paddle for use with Navigator is shown below. If your paddle is already wired, and DIT and DAH are reversed, you can correct for polarity with the SWAP option in the WK2MGR program. Ring Shield Shielded Cable 1/4"...
The items shown can be selected and set by a mouse click on the item button. Each time the option set is changed, a new copy is sent to Navigator and the setting is immediately used. If you don’t like the changes you have made, click the “Restore Default button” and it will be put back the way it was.

Another feature of the Navigator Option software is the ability to scan connected ports to find a valid Configuration port. If there are two or more Navigators installed, port numbers of both interfaces are displayed so that you can select the one you want.

6 Installation Detailed installation procedures are found on the Navigator Distribution CD, in the DOCS folder. This section covers a summary of Installation Planning, Driver Installation, Application Software Installation and Setup, and Rig Hookup. 6.1 Installation Planning The table below shows the parts of the installation procedure, and the recommended sequence of installation.

Detailed procedures are provided for hams who have not been through setup of an interface system on USB interfaced devices.

– especially in the area of FSK interfacing for RTTY operations. The need for a stable solution to these conflicts between hardware and software, has led to the architecture and design of the Navigator Interface. This device provides a built in 4 channel USB hub, a USB Audio Codec, Serial Port converters, and microCPU controllers for FSK and CW.

A partial list of control programs is found in the table below. In general, if you use COM port 8 and less, you can cover most if not all of the available programs. To do this, you must assign 4 of the 6 COM ports needed for Navigator to COM8 or less to cover all of these programs.

6.1.3 Recommended COM Port Assignments While the COM ports of Navigator can be assigned a COM port up to 255, software restrictions often dictate that they should stay in the first 8 ports. Stay away from using COM1 through 3, since they may be taken up by “real” ports instead of USB assigned ones.
The driver package is completely removed. 6.4 Application Software Installation See NavInst3 MixW and NavInst4 MixW Setup for procedures to install and setup the MixW program with Navigator. These procedures serve as an example of application software setup for use with the Navigator.
Connection to your rig involves installing a cable between the Navigator “Transceiver” connector and your rig. See the www.USInterface.com website for a full list of cable drawings for use with the Navigator. An example below shows the connection of the Navigator to an Icom 756 transceiver. Mates with...

MMTTY setup puts the stop bits at 1.5. MixW likes it set to 2. If you did not change the stop bit setting in NavOptions, then MMTTY sent it’s data faster to Navigator than the output rate. There is a FIFO buffer in the FSK Controller, so that all of the data was received by Navigator, but it was still sending when MMTTY thought it was through.

Normally, the ALC takes care of these differences, since for voice the levels are boosted to attain a full sound anyway. With digital modes, you are operating in the linear range, below the ALC level. Use the RF OUT control on Navigator to bring the level to where you want it.
Page 35
Q. What about FSK RTTY and CW? How do I adjust the power level with those modes? A. These modes do not use the Audio Codec to generate the signal. The power levels are determined within your rig. Use the rig power level to control output power.
