Product Information
The AXB-EM232 Enhanced Master RS-232 Controller (FIG. 1) is an AXlink bus device that
functions like an AMX Master Card in a single compact enclosure. It is fully compatible with the
Axcess Control System and can be used either as a stand-alone device or with other AMX bus
devices. The AXB-EM232 runs complete Axcess programs, and controls other AXlink components
and two devices using RS-232 as a control protocol. It can also control devices using RS-422 and
RS-485 protocols.
