The TAP (Tigo Access Point) is Tigo's latest radio transceiver with integrated antenna. It replaces the Gateway and has the same function. Like the Gateway, the TAP allows wireless communication between the Cloud Connect Advanced (CCA) and the TS4 optimizers using a RS-485 cable from CCA to TAP(s).
Mesh is software that allows each TS4 to act as a repeater, extending the range of the TAP. The signal and data can hop from TS4 to TS4 along many different paths.
This allows much more flexibility in system design and layout. The TAP can be placed almost anywhere in or near the array, as long as the simple TAP Placement rules are followed. Obstructions are not a problem, since each TS4 doesn't need to communicate with the TAP directly.
Site Conditions Affecting Range
The site conditions can affect range. For example, in a U-shaped array the range may need to be measured around the shape of the "U" since the direct distance (red arrow) is more than 10 meters. See below.
Another example is a metal stepped factory roof. A metal roof like this is considered an obstruction, so a separate TAP may be required for every roof face, even if they are less than 10 meters apart. See below.
You must have the following in order to use Mesh software:
- TS4 UHD-Core
- Cloud Connect Advanced (CCA)
- TAP or Gateway
