This article covers the basics of a TAP (Tigo Access Point):

TAP Description
The TAP is a wireless radio transceiver (gateway). Its bracket clips onto the module frame; however, the clips are removable for rail mounting when using frameless modules.
TAP Wiring
The TAP has an integrated antenna that sends/receives data wirelessly from the Tigo TS4 MLPE's (O, S, and M models).
Once installed, it must be hard-wired to the CCA (Cloud Connect Advanced) via a data cable (not included with equipment):
- RS-485 or Ethernet cable can be used to connect the TAP with the CCA
- RS-485 or Ethernet cable can be used to connect multiple TAPs (daisy-chain)
- A CCA can operate with up to 7 TAPs (max)
For more wiring guidelines, see: TAP Communication Cable Guide.
TAP Communications
The TAP is part of Tigo's Wireless Mesh system, which requires a line-of-sight for communication. TAP signal radius is 33ft / 10m and must be centered within its array (for maximum coverage)
- Multiple TAP systems must have at least 50ft / 15m distance between each TAP.
The TAP antenna radiates most of the signal horizontally (from the side or narrow edge), with a reduced signal coming from the front or back of the housing.
For additional information on design considerations (regarding obstructions and/or interference), see: Tap Placement and Layout
Mesh Requirements
Tigo uses a wireless Mesh network (WMN), which consists of radio nodes organized in a Mesh or Web-like topology.
This allows the TAP to communicate with only the TS4 MLPE units within its 33ft / 10m radius. Then, those units act as radio relays, to transmit data to and from units, that are beyond the radius' threshold.
- Minimum of 5 TS4s must be placed within the 33ft / 10m radius of each TAP
- Maximum of 33ft / 10m distance between each Tigo MLPE
- Maximum range from TAP to the furthest TS4 is 115ft / 35m
- Multiple TAP systems must have at least 50ft / 15m distance between each TAP
This is a linear illustration of the maximum signal 'hop' distance between the TAP and the optimizers.
