CGA SB2000MK2 Interface

The CGA SB2000MK2 interface connects your computer to your radio transceiver. Through one interface, you can use CAT/CI-V rig control, operate digital modes, and control functions like PTT, CW, and FSK. The galvanic isolation between the computer and transceiver helps prevent ground loops and unwanted interference.

The SB2000MK2 is suitable for radio amateurs who want to use their Yaesu, Icom, or Kenwood transceiver with a computer. With the correct optional interface cable, you can connect various compatible transceivers.

What does the CGA SB2000MK2 do?

The SB2000MK2 brings together the various connections needed for communication between radio software on your computer and your transceiver. Instead of using separate solutions for audio, CAT control, PTT, and CW, these functions run through one central interface.

For CAT or CI-V control, the interface handles communication between suitable radio software and the transceiver. This allows software, for example, to exchange data about the set frequency and band with the radio.

The audio connection between the computer's sound card and the transceiver also runs through the SB2000MK2. This allows you to use digital modes such as RTTY, PSK31, SSTV, and FAX. The interface can also be used for CW, FSK, and PTT control, and for recording SSB conversations via the computer.

Two virtual COM ports via one USB connection

A significant improvement of the SB2000MK2 compared to the earlier SB2000 is the use of two serial connections. The MK2 uses an FT2232 USB-to-UART solution for this and offers two virtual COM ports via a single USB connection.

This allows, for example, CAT/CI-V rig control and other communication or control functions to be used side by side.

The connection to the computer is made via USB 2.0, eliminating the need for a traditional serial or parallel connection to the computer. The interface also gets its power via USB, so no separate power adapter is required.

Galvanic isolation between computer and transceiver

When connecting radio equipment and computers, good electrical isolation is important. The CGA SB2000MK2 uses optical isolation for digital signals. The audio connection is separated with a 1:1 audio transformer.

This galvanic isolation helps reduce ground loops, voltage differences, and unwanted EMC interference between the computer and transceiver. This makes the SB2000MK2 a well-thought-out solution for a permanent shack, but also for portable and mobile radio setups.

Capabilities of the CGA SB2000MK2

• CAT and CI-V control of compatible transceivers
  
• Digital modes such as RTTY, PSK31, SSTV, and FAX
  
• Control of PTT, CW, and FSK via the computer
  
• Galvanic isolation with optocouplers and 1:1 audio transformer
  
• Two virtual COM ports and power via a single USB connection

Applications such as EchoLink and recording SSB audio via the computer are also possible, depending on the transceiver and software used.

Which transceivers are suitable for the SB2000MK2?

The CGA SB2000MK2 can be used with various transceivers from Yaesu, Icom, and Kenwood, among others. For this, you need an interface cable suitable for your specific transceiver.

Various optional CGA cable sets are available. The ACC-101, ACC-104, and ACC-105 are intended for various Yaesu models. For Icom, the ACC-102 and ACC-103 are available, among others, and for various Kenwood transceivers, you can use the ACC-106 or ACC-107.

Always check which cable set belongs to your exact brand and type of transceiver before ordering.

One interface for computer control and digital radio

Do you want to use digital modes, control your transceiver from radio software, or control CAT/CI-V, PTT, and CW via your computer? Then the CGA SB2000MK2 radio interface conveniently brings together the necessary connections.

Thanks to its USB connection, two virtual COM ports, and galvanic isolation, the SB2000MK2 is a practical interface for the radio amateur who wants reliable cooperation between computer and transceiver.

Order the CGA SB2000MK2 and choose the appropriate interface cable for your Yaesu, Icom, or Kenwood transceiver.
