PL-TREE-COM Principles 1. The Prolon PL-TREE-COM is a wireless communication device that transmits and receives Modbus RS485 data over radio frequency communication (2.4GHz) 2. Its goal is to wirelessly extend, complement, or replace standard RS485 wired daisy-chains, where a physical connection would be impractical or uneconomical.

Figure 3 5c) The PL-TREE-COM radio wave pattern is directional, meaning the signal beam, while able to radiate everywhere, will travel farther in one specific direction. The built-in antenna is aligned with its front cover (face with the lights and dipswitches). In order to achieve maximum range, or communicate through complex building structure, both PL-TREE COM modules commu- nicating together should have their faceplates facing each other.

7. LEDS The PL-TREE-COM comes equiped with five LEDs to indicate device status. (Figure 5) 7a) HBEAT (BLUE): This LED simply indicates that the device is powered and operating. It should blink once every second, regardless of RS485 or Wireless communication.
Single-Zone Unit Controllers with Digital Wall Sensor The RTUS, HPS or FCU controllers can be connected to their respective wall sensor using the PL-TREE-COM device. 1. The PL-TREE-COM connected to the communicating wall sensor must be set as the "ROOT".
PL-VC2000 with Digital Wall Sensor The PL-VC2000 or C1050 VAV controllers can be connected to a digital wall sensor (T1000, T500,T200) using a PL-TREE-COM. (Figure 8) **Important** A PL-RS wall sensor CANNOT be connected using a PL-TREE-COM. 1. The PL-TREE-COM connected to the communicating wall sensor NEEDS to be set as the "ROOT". (INT port) 2.
1. Each controller must have its own dedicated PL-TREE-COM device 2. The PL-TREE-COM connected to each Zone Controller must be in set as the "LEAF". (NET Port) 3. The PL-TREE-COM connected to the Master Controller must be set as the "ROOT". (NET Port) 4.
1. The PL-TREE-COM on the M2000 Master's side must be connected in the NET port and be set as the "ROOT". 2. The zones Network PL-TREE-COM can be inserted anywhere in the daisy chain of the Zones. This device must be set as the "LEAF".
(wired/wireless - hybrid network) Example 2 A wired communication network can be spliced and re-united using TREE-COM modules, regardless of their location within a Prolon network. (Figure 11) 1. The TREE-COM that is hardwired to the Modbus Master (PL-M2000-RTU) must be set in "ROOT" mode 2.
1. The PL-TREE-COM connected to the PL-NC2000 via the RS-485 OUT port must be set as the "ROOT". 2. The PL-TREE-COM connected to individual PL-M2000, or PL-C1050 via the INT communication port must be set as the "LEAF". 3. All PL-TREE-COM modules must have their dipswitches set for the same channel number.
Measuring signal quality with NFC 1. The incoming signal quality from a "ROOT" must be measured at a "LEAF" device, using the Prolon Focus app on a mobile device with NFC capabilities. 2. A measurement only becomes possible once a connection has been established with the "ROOT" module.

Low signal quality best practices A signal quality of 30% to 60% is considered low quality. To communicate succesfully with signals in this range, it is best to increase the number of retries in Focus (PC) or mobile app to 10 or 20 attempts, so to reduce the likelyhood of failure. Here is the procedure: 1.
