DGeneral description You can get I/Q signals from the [USB 2] port on the IC-7610 by connecting the IC-7610 and a PC, with a USB cable. You can receive I/Q signals and control the IC-7610, through the USB cable.

Requirement: IC-7610 firmware must be version 1.20 or later. Windows 7 /8.1/10 PC (32 bit or 64 bit) USB 3.0 or higher USB I/Q driver (USB I/Q Package for HDSDR)

You can download it from the Icom web site. (The software is commonly used with HDSDR*.) *An SDR receive software (freeware). You can download it from: http://www.hdsdr.de/

DGeneral description I/Q signals and IC-7610 control commands are exchanged through the [USB 2] port on the IC-7610.

DAbout the Device Description The Device Description, that is needed to open the [USB 2] port, is shown below.

IC-7610 SuperSpeed-FIFO Bridge

DAbout the endpoints The IC-7610 has 3 endpoints. Each endpoint is reserved to receive I/Q data, to send control commands to the IC-7610 and to receive the acknowledgement from the IC-7610.

The communications are done through FTDI's D3XX Driver. You need to install the driver (USB I/Q Package for HDSDR) that can be downloaded from Icom web site. After the driver is installed, you can receive I/Q signals and control the IC-7610 through the D3XX Driver, using an I/Q receive software (user supplied). To receive I/Q signals and control the IC-7610 from the user application, you need FTDI's FTD3XX.dll. Refer to D3XX Programmer's Guide that can be downloaded from FTDI web site on how to use the functions.

You need to set the device description and appropriate endpoint. Refer to the next topic for details about them.

DGeneral description I/Q data is output from the [USB 2] port on the IC-7610. One endpoint is reserved to receive I/Q signals.

The sampling frequency, Bit depth and I/Q signal bandwidth are fixed as follows.

About the I/Q signals

Address (Hexadecimal) Direction Endpoint Number

(Hexadecimal) Transfer Type

I/Q data IC-7610 PC 84 IN 04 Bulk transfer

Sampling frequency Bit depth Signal Bandwidth Band (Main/Sub)

1.92 MHz 16-bit 1.66 MHz Main or Sub (Selectable)

TIP: The sampling frequency can be set to 960 kHz or less in the HDSDR application. You can select the Bit depth in the HDSDR application. These are achieved by processing down sampling and bit conversion on the PC.

D I/Q data format Data format: The I/Q data is composed of 2 parts: I signals and Q signals. Each data length is: I =16 bits (2 Bytes), Q =16 bits (2 Bytes). (The byte order is in the little-endian format.)

I I QQ 2 bytes 2 bytes

I I QQ 2 bytes 2 bytes

I/Q data range is 32768 (0x8000) ~ +32767 (0x7FFF). I/Q data is formed in increments of 4 bytes. Therefore the most significant byte must be an I signal.

I/Q SIGNAL

DGeneral description The following 2 endpoints are reserved for sending control commands: Sends the control commands from a PC to the IC-7610. Sends the acknowledgement from the IC-7610 to the PC.

DCommand format You can control the IC-7610 using the CI-V commands. Every command is composed of a byte array in hexadecimal. Every command byte must be in increments of 4 bytes. After sending a command from the PC to the IC-7610, an acknowledgement is returned. When you send commands one after another, you need to send the next command after the acknowledgement is received.

Writing command format: Send a writing command from the PC to change an IC-7610 setting. A writing command is composed of a command number and setting data that follows the command. The IC-7610 will return the result as an acknowledgement after receiving the command.

LThe control command format is based on the ICOM Communication Interface V (CI-V) format. LThere are 2 command types: Writing commands and Reading commands. Refer to the next topic for details about them.

Reading command format: Send a request command from the PC to request to return an IC-7610 setting value. A reading command is composed of only a command number. The IC-7610 will return the requested setting value as an acknowledgement when receiving the command. If the request command is invalid, NG (FA) will be returned as the acknowledgement.

NOTE: When the data length is not in increments of 4 bytes Every command must be in increments of 4 bytes. If the command is not in increments of 4 bytes, you need to add an extra FF at the end of the packet, to make the command length a multiples of 4. In the same manner, the length of the acknowledgement data from the IC- 7610 is a multiples of 4.
