CoolMaster 3000T
RS232 Interface Adapter for Toshiba VRF Systems

 

General Description

 

CoolMaster 3000T is versatile bridge device connecting Toshiba VRF Air Conditioning systems and any RS232 or USB capable device like Home PC, Embedded PC or Home Automation Controller. Exposing simple interface over RS232 communication line or USB bus, CoolMaster gains user application full control on indoor units and provides access to VRF system parameters. In other words CoolMaster hides complexity of internal Toshiba Communication line (including very unique physical layer) and instead gives simple, comprehensive, well documented protocol running on popular RS232 or USB connection.
