I will make another attempt from my side, since I still think you are asking something else:
- You must have a radio RRC on the station side. This connects up to the radio and network and
provides audio, control (CAT) and the possibility of controlling an additional serial device, such as
a rotator. No computer on the radio side is required (that is the main advantage of the RemoteRig).
- On the user side, you have three possibilities:
1) Another RRC for control, which connects to the one at the station. If you have a rig with a separate
control panel (head), such as the TS-480, IC-706, etc., then you can use this panel to remote
control the rig. A computer is optional, but can be used for CAT control or controlling the additional
serial device.
2) You can use a control RRC without hardware control, only using a PC software to control the
rig using CAT. Essentially the same as last, only that you lose the comfortable hardware-based control
with the panel/head. This method is necessary when using a rig that doesn't have a remote panel.
3) You can buy the RRC PC Micro client and save money over the RRC solution. This gives you essentially
the same as the previous method, except that you lose CW paddle support. You gain portability, since
this is very small and light. Many like me have this as a backup method of access when traveling.
Hopefully this answers your question.
