COM Port Expander for PYNG-HUB

The Crestron PYNG-CONNECT-COM is a COM port expander that allows a PYNG-HUB to interface with a home’s security panel via RS-232. As a result, users can check the status of the security system and arm or disarm the system directly from the Pyng app.

The PYNG-CONNECT-COM includes one RS-232 COM port for connecting to the security panel and one Ethernet with PoE port for connecting to the PYNG-HUB. Its tiny, Crestron® IFE micro form-factor allows the PYNG-CONNECT-COM to be placed just about anywhere, with the option to attach it to a flat surface or DIN rail using the mounting bracket provided.
