My intention is to use the RTS fron CAT the serial port (pin 7) to drive the above pins 2 - 3. It seems that if I short the pins 2 and 3 on the DATA PACKET (on the back of the transceiver) I can transmit and hear the tone while transmitting (I made just a quick test). The input threshold voltage Vih Vil is about 5v - 2 Vbe 3.

The emitter of Q1 and pin 14 of IC16A is 5 volts when operational. Ive made small changes to the modem control signals connections. Here is a very simple CI-V interface, originally described by OK2WY. A few circuits have been published for CI-V interfaces, most of which use the MAX232 IC. It does not happen if I use the Breack-in, without driving the PTT. To try to understand Icoms think about the CI-V bus, we will look at one of the interfaces within a radio. Icom appears to delight in charging outrageous prices for all transceiver accessories, so many Hams improvise instead. In other words, I can not hear what I am transmitting. If I connect the interface PTT contact to the transceiver, it switch normally but the transceiver is getting silent during transmission. The interface has the CAT and CW output as well as a PTT contact to switch the transceiver to TX when I transmit CW. Regarding the PTT, I use an interface connected to the USB port. This is a nice little circuit using a couple of 2N2222s, two diodes, and four. The page on CI-V level converters has links to many different circuits, including a relatively complicated one using the MAX232 chip.

It allow the socket to move making difficult to insert the plug. This is a complete online manual to the interface and the software driving it.

) The PDF has this, This Guide applies to newer Icom HF radios with a USB interface, such as the IC-7200, IC-7850, IC-7851, IC-7300, IC-7610, IC-7600, and IC-7100. Just a remark, the USB socket matallic shield (control side) was not welded to the board. Icom Ci V Interface Guide Quan vaig comprar l’Icom 7300 ja vaig veure al seu manual d’instruccions l’esquema per a poder fer un keypad. After retyping more time all the parameters, the CI-V is working now, I can not say what was the wrong data.
