Icom Communication Interface - V. This is a system, which provide advanced remote control LAN for multiply transceivers. More details can be found in attached icom-civ.pdf document. Also a bit info in russian can be found at my blog post. ICOM IC-820 transceiver has a poor support of remote control. RRC-1258MkII also supports the CI-V protocol used by almost every ICOM radio. Then you have to use a PC-software ex. HamRadioDeLuxe or a similar rig control software at the control site. All audio and data communication goes true the RRC:s so you don’t have to worry about the audio quality.
Each message (frame) sent to a rig or received from a rig contains two adresses. The destination (to-adress) and the sender (from-adress). Each model has it's own default CI-V adress, which can be changed by the user. If two or more rigs of the same model are used on the bus (or level converter), you need to change the adresses of the rigs, each individual rig must have it's own, distinct adress.
The 'Icom CI-V Reference Manual (3rd edition)' from 1991 specified the adress range from $01 to $7F. That range was exhausted in 2010 with the IC-9100. But Icom has been happily using addresses above the originally specified range without any issue. Now (Aug. 2020) we are at address $A4 (IC-705). With a rate of 1 to 2 new rigs per year that leaves room until 2036 or so :). But then there are the odd addresses which haven't been used at all in amateur radio products. Values $FA to $FF are reserved for special protocol functions.
$FE | $FE | to-adr | fm-adr | Cmd | Sub | Data | … | Data | $FD |
There are some reserved adresses with special meaning:
- $00: Used as to-adress, means all connected rigs.
Any rig with CI-V Transceive set to on should react to commands adressed to $00.
Any rig with CI-V Transceive set to on adresses it's messages to $00 when tuning the dial, changing mode etc. - $E0: Reserved for the controller, i.e. the computer. But to my knowledge no rig really cares where the messages come from, so any adress could be used as from-adress.
- $FA … $FF: Reserved for protocol functions such as frame delimiters, Ok, Not-Good, collision signals, empty memory etc. These values must not be used as adresses.
Default adresses
Each Icom model has it's own, distinct default adress. As a general rule, Icom used only even adresses ($02, $04, $06 ...). Each model was given a new default adress when it came out. The user can change the default adress if required. On older rigs this was done by (re-) soldering some diodes, on newer rigs the adress can be changed by setup through the front panel or even by CI-V commands. Adresses can be selected from $01 to $EF, giving 239 distinct adresses.
The following is a nearly complete table of all known adresses from CI-V capable rigs, not only by Icom.

The same list, sorted by adresses. Since Icom assigned adresses in an ascending order when new radios came out, it gives a historical overview of the rigs appearance on the market (mostly, with some irregularities and gaps). This list shows only Icom rigs, not those of other vendors capable of the CI-V protocol. The years when the rigs appeared on the market are from my memory, info gathered at work or from www.rigpix.com (tnx!).

Icom Ci V Interface
The Icom IC-746 covers 160-10 meters plus 6 and 2 meters. 100 Watts of output is available on all bands - HF, 50 MHz and 144 MHz, making the IC-746 a practical choice for all-around base station use. The die-cast aluminum chassis and a large cooling fan help to stabilize the PA circuit, providing 100% full duty cycle operation. It has 100 alphanumeric memories, spectrum display, Twin PBT, CTCSS encode/decode, APF, two stage preamp, keypad entry, automatic antenna tuner and electronic keyer. DSP digitally transposes receive audio components in all modes of operation to produce desired AF frequency characteristics at the IF stage of the transceiver. This built-in DSP provides: noise reduction, automatic notch filter and selectable APF. The digital bar graph meter displays ALC, power output and SWR simultaneously! The radio automatically selects from the three separate antenna inputs (HF, 6 meters, 2 meters). A built-in automatic antenna tuner operates on the HF bands plus 6 meters. The rear panel has three antenna jacks. The 746 requires 12 VDC at 20 Amps.
Icom Ct 17 Interface
The IC-746 comes with HM-36 hand mic, spare fuses, DC power cable and key plug. 11.3 x 4.8 x 12.5 inches. 20 lbs.
