Our Comments About This Crestron ST-COM 2 COM Port Module:

This Crestron ST-COM 2 COM Port Module is a used item that is in very good condition that was bench tested and is fully functional. This Crestron ST-COM is overall in near excellent cosmetic condition with a newly painted outer cabinet shell. There is minor blemish to the front vinyl face. Cosmetically the outer cabinet is in excellent condition with the four rubber feet installed to the bottom of the unit's cabinet. We conducted a bench test on this ST-COM by connecting it up to a  Crestron AV2 processor and ran it using a demo test program.  This ST-COM was tested to insure it functioned to receive and transmit a serial strings from each of the two ports.  

In conclusion, this Crestron ST-COM 2 COM Port Module is functioning properly by successfully passing our bench test and is guaranteed by us to be ready for installation. 

 

Manufacture's Quote: 

The ST-COM is a Cresnet® expansion module that provides two independent bidirectional RS-232/422/485 COM ports. Typical applications include control of display devices, switchers, lighting systems, security systems, and more. The ST-COM may be used to provide a serial control interface at a remote location, or may be rack mounted in the central equipment cabinet to expand the number of control system ports (ST-RMK rack mount kit sold separately). Communication with the control system is via a single Cresnet connection.
