In the right part, you’ll find CAT and VAC settings.
RUMLOG N G WINDOWS SOFTWARE
In the left part of the software window, you need to enter the IP address and port of the TCI server in ExpertSDR3. This utility was created to synchronize ExpertSDR3 software and other third-party software without TCI support via CAT and VAC.
Here is the link to the GitHub page, where you can find the description of the TCI in English and Russian and the source code of the demo-client software. The connection process with TCI is very easy, someday in the future, you won't believe you lived without it for so long! Several software developers are already working on the implementation of TCI in their software, we will try to get TCI into all HAM software. For example, Band Pass Filters unit with a LAN interface can get information about radiofrequency via LAN and can switch filters, the same applies to antenna switches and PAs, and so on. This is a game-changer for the SDR radio! It is an open-source protocol, we've discussed using it with hardware and accessory developers. It was developed as an open protocol to use with multi-band transceivers, which support one, two, or multi receivers/transmitters.
TCI is the universal multi-client interface (you can connect it to radio Loggers, Skimmers, PAs, antenna switches, etc. TCI has all required control commands similar to the CAT system, but even more, it can transfer IQ-streams from the ExpertSDR2/3 to clients (third-party software such as signal Skimmers, etc.) via local network and the Internet, CW macros and Audio In/Out streams for digital modes. TCI - Transceiver Control Interface was developed for simple and still advanced connection between the ExpertSDR2/3 and third-party software.
