RTI’s CPB-1 Control Port Connecting Block By RS Staff Published: April 7, 2009 ⋅ Updated: April 15, 2019 Shakopee, MN–The CPB-1 Control Port Connecting Block provides a cost effective solution for one-room installations such as classrooms, that require an in-wall controller and both infrared and RS-232 control of local devices. The CPB-1 provides power to one RTI in-wall system controller and has two output ports that allow the connection of up to two single or dual infrared emitters. It also incorporates an RS-232 port for control of devices without the need of an RTI processor. For integrators, the cost-effective solution powers an RTI in-wall controller while providing both infrared (IR) and RS-232 control of local devices.
