SB-2000 MK2 USB Radio Interface

If you love our SB-2000 USB radio interface, but you would like to have an extra serial port to run rig control and digital operation at same time. Now we release the new update SB-2000 MK2 USB radio interface. It uses new FT2232 chip to support 2 serial ports. You could perfectly enjoy your computer software working with your radio transceiver.

1.Connect your computer with USB port. No need serial or parallel port
Most of Radio programs are built based on COM serial port of PC computer. But the most latest PC computers don't have a serial port.
2.USB to UART bridge by FT2232 single chip. USB 2.0 compliant. Full speed.
To be compatible with the legacy radio program, we still have to keep using serial port. That's why we choose to use USB to UART bridge which converts the USB to serial port. The new FT2232 supports 2 serial ports. Therefore user could use 1 port for rig control and another port for digital operation.
3.CAT, CI/V controller and audio transformer are combined together.
No sophisticate software setting. Very clearly operate from reachable setting on the control panel. It supports CAT with RS232 protocol. So ití»s compatible with the most latest transceivers.
4.Complete isolation between computer and radio station.
Optical isolation used for digital signal.
Audio signal isolated 1:1 transformer. It has internal static isolation. Excellent EMC(Electromagnetic compatibility)

5.Operated by computer USB power. No need extra power.
When you are in your expedition or mobile, you will not have extra power headache with SB-2000. It uses the power from your computerí»s USB port.
6.Very compact size, easy to carry.
Weight less than 400 grams. Pocket size only.
7.Supply with full accessories.
It comes with USB, CAT or CI/V, Data and audio cables.

SB-2000 links your radio transceiver with the computer.

You can control your radio if it supports CAT or CI/V protocol from your computer.
2.Operate RTTY, PSK31, SSTV, FAX, etc. digital mode.
From your computer you can easily operate digital mode with proper software. Turn your computer into a professional expensive DTE.
3.Transmit and receive CW.

Although SB-2000 MK2 supports the CAT/CIV connection up to 38400bps, but we strongly suggest user to set at 9600bps.

Once you connect the SB-2000 MK2 to your computer, there will come out two serial ports. Always use the first one as digital operation and the second one as rig control.

For some yaesu transceivers, if it can not be transmitted due to low AF-input level. Please check the transceiver's manual for increasing the AF level.
For some yaesu transceivers, if there is a menu item which named is CAT RTS. Please set it off. Then the CAT function will work properly.
