SB-2000 Mk2: Soundcard and CAT Interface with USB control

To avoid any misunderstanding: The SB-2000 is an interface for an already existing sound card that is installed in your PC. It does not contain its own sound card!

The SB-2000 Mk2 is a inexpensive transceiver interface with USB connector (USB 1.1 and USB 2.0 full speed are supported). There is no need for a legacy serial or parallel port on your computer. The interface contains a CAT interface for transceiver control incl. PTT, FSK an CW keying, as well as a soundcard interface for digital modes like RTTY, PSK32, SSTV, FAX etc. (using the soundcard of your computer).

The new 'Mk2' version of the SB-2000 interface now supports two virtual serial ports! This is very useful since not all computer programs can support mixed functions like PTT and CW keying plus CAT on the same serial port. With the new version you have two virtual serial ports, one for PTT and CW/FSK, and another port for CAT control.

All signals are insulated optically or by transformers. Power supply is done over the USB line from the computer. Included in shipment is a CD with USB drivers for Windows 2000, XP, Vista and WIn7. MacOS X and Linux are supported directly and do not require driver installation. Size 130x75x45mm.

The drivers for Windows and OSX are available for download here:

SB-2000MK2 driver for winXP
SB-2000MK2 driver for win7, win8 and win10
SB-2000MK2 driver for OSX (From 10.9)
SB-2000 driver for win7-10

The separately sold cable sets include all cables necessary for all connections (CAT and data to radio, USB and Audio to computer). The SB-2000 Mk2 includes a level converter from RS-232 to USB, allowing the use of radios with RS-232 interface (FT-1000, FT-2000, FT-450, FT-950 etc.). The connection to the radio is done with a multi cable which also includes the CW keying signal. The CAT interface works up to a max. speed of 19200 Baud.

Note: Some radios which support HF and VHF (e.g. IC-746, IC-7400) do have separate PTT lines for HF (HSEND) and VHF (VSEND). The SB-2000 keys only the HSEND line, so without modification it is useable on HF only. To use the interface on VHF/UHF as well, you need to modify the radio or interface connector to key HSEND and VSEND simultanously (bridge HSEND and VSEND). Radios like the IC-706Mk2G and IC-7000 needs to have a menu item set, so HSEND also keys the Tx on VHF and UHF.


Note on using the SB-2000 with the Icom IC-7000:

The cable SB2K-IC13 has an internal bridge between the keying lines for FSK and CW. This allows the keying with just one line, the RTS signal, and works just fine with the IC-706, IC-7200 etc. But with the IC-7000 a high current is seen over these lines. The effect is that the fan starts immediately after plugging in the cable. In rare cases the IC-7000 might be damaged.

Quick solution: Don't plug in the CW connector from the SB-2000 to the IC-7000. The renders the interface inoperable for telegraphy. Other modes like PSK31, RTTY etc. are not affected.


Note on SB-2000 and FT-847:

The SB-2000 USB interface can be operated of the FT-847 under certain circumstances.

1.) To use the CAT functions you need a cross-over cable male/female. This cable needs to cross pins 2 and 3, pin 5 is connected straight through, all other pins can remain unconnected. WiMo does not offer suitable cables, sorry. A converion of existing cables offered by WiMo is not possible because the connectors are sealed.

2.) To make use of the audio signal on shortwave (for PSK31, AFSK etc.), a home-made cable with 6pin female Mini-DIN connector and a 3.5mm Stereo phone connector is required. The PTT line and the audio output are connected to one wire by using a resistor and a capacitor, see page 16 in the english language manual on how to connect a TNC to the radio). Unfortunately WiMo can not offer such a cable, sorry.
