You might run HDSDR as a panadapter, with OmniRig providing CAT control to it, and you might also run your digi-mode software, and logging software, all of which need access to the radio’s CAT data on the same COM port. If for example you have OmniRig running in the background, then start HRD, you’ll get that good ol’ DOS-days error, “COM port already in use.”Īctually, there’s a way around that-a utility called VSPE (Virtual Serial Ports Emulator), whereby you map a real (or virtual) serial port to a new virtual port, then point as many programs as you like to the new port, and all can use it at the same time. Note also that two programs cannot share the COM port. In your rig control software settings, pick the first COM port and set it to 19200, N, 8, 1, and CTS/RTS doesn’t matter I set them to “Forced Off.” Note that if you have a 7300, you can use them and there are settings for their functions in the 7300’s Connectors menu. Update 2 (12/02/20): fldigi now supports CW keying via CAT! So no external keying interface needed. It’s called “LD-C103” and is a generic/unbranded part. It apparently contains (in the USB plug) a USB to UART bridge chip (it presents a virtual serial port to the computer), and uses RTS and a switching transistor to key (ground) the radio’s CW jack. Update 1: I found a little device for $10 that simply plugs into a USB port and the radio’s CW Key jack. You must use software that will PTT via CAT command, so older software that only sends PTT and CW keying via serial pins will not work. The radio’s serial UART chips present RTS and DTR states, but the 7100 does not use them, so forget about PTT or CW keying via virtual hardware pins in your digi-mode software. It can be set to output RTTY or DV data messages (to an ASCII terminal emulator software), or used for a NMEA GPS for D-Star. The second COM port is called USB2 in the radio. This is the CAT (Computer Aided Transceiver, Icom CI-V commands) port you’ll use in all your radio software that provides and uses radio control. The first com port will be called USB1 in the radio’s docs and menus. They will appear as “Silicon Labs CP210x USB to UART Bridge” in Device Manager, under the “Ports (COM & LPT)” branch of the device tree. In Device Manager, and programs that access COM ports, you’ll find two new (virtual) COM (RS-232 Serial) ports, named like COM3 and COM4 (or 5&6, or 7&8, if you already have some real or virtual COM ports). AFTER installing the driver, reboot, then plug in the USB cable, and then turn on the radio. Unzip it and click CP210xVCPInstaller_圆4.exe (or _x86 for 32-bit Windows). It has detailed instructions and screen-shots for Windows 7, 8, and 10.ĭownload the latest USB Driver (Version 1.30 ), Driver Utility and manuals. Read the Icom USB Driver Installation Guide. The soundcard chip in the 7100 requires no special driver Windows idetifies it as a “USB Audio Codec” and uses a generic driver, just like if you plugged in any USB soundcard dongle. That’s the manufacturer of the USB-to-serial UART chips used in the radio. Actually, it’s not an Icom driver (though you get it from them), it’s a Silicon Labs CP210x driver. (Skip to Audio Setup, if you’ve already done this)ĭo NOT plug in the USB cable before downloading and installing the Icom USB Driver! If you do, Windows will automatically install a generic serial driver, and you’ll have to go into Device Manager and remove it, then install the Icom-provided driver. Read that, then return here and read details for the 7100. Save the PDF, as it has much more info, with dialog box pictures, about setting up the computer, radio, and several popular digi-mode programs. Update (2021):See also this 2018 ICOM Knowlege Base PDF: Configuring Icom radios for USB Operation. In effect, they added a SignalLink USB-type device to the radio.īut we still need to set up those devices, so follow along by opening and adjusting your Windows “Sound” dialog box, and the radio’s Set → Connectors menu. To use them you just set them up, then pick them from a list in your software’s audio and CAT setup, just as if they were external USB dongles or computer-to-radio interface. What this means is that the radio contains a USB hub chip, two serial port chips, and a soundcard chip (just as you’d find in external interfaces) that presents a soundcard and two serial (COM) ports to the computer. Like most modern ham radios, the Icom IC-7100 comes with a built-in USB audio and serial devices, providing a one-cable connection to a PC without needing an external interface box, dongles, or audio cables.
