4.1.1

PBUS

PBUS is a CoolAutomation’s proprietary bus interface, based on shielded 2-wired cable (AWG24). It utilizes

free network topology. 

PBUS is intended for connection of CoolPlug and ThermoPad devices to CooLinkHub.  PBUS is a solution

for complete integration of (multi) split HVAC units with Home Automation and BMS systems.

4.2

RS232 Port

RS232 Interface in CooLinkHub is available from the RS232/IO connector. RS232 harness, provided with

CooLinkHub, routes RS232 signals to DB9 connector as shown below.
