Model 9044 Binary Application Monitor (BAM)
The Binary Application Monitor (BAM) is a monitoring unit that has 24 sets of binary input/output points and three alarm relay output points. Two four-pin alarm output points are floating “Form C” relay contacts plus ground. The third is a two pin solid-state contact closure to ground. These inputs and outputs are provided on polarized detachable plug-in screw terminal blocks on the rear of the unit. The BAM can be installed in stand-alone or remote controlled applications. In stand-alone applications, the unit provides local indications of alarm input conditions, as well as contact closures that can forward these indications to other equipment. BAM units can be cascaded in a tree configuration such that one BAM monitors the aggregate status of 24 other BAM’s, and so on. In Telecommunications installations, this is called a “Rack Alarm Gathering Unit” (RAGU). The BAM can also be remotely monitored, either by two-way RF or via a baseband RS-485 connection to AM’s OmniMCU. In this configuration, BAM information is integrated with the many other types of monitoring data that are needed to assess overall performance of an HFC network. The BAM front panel has indicators for each input/output. These indicators respectively display green if the point is in its preprogrammed normal state, flashing red if the input has an unacknowledged alarm condition, and continuous red if the point has an alarm that has been ac nowledged, but not cleared. The 24 BAM digital I/O ports are programmable via two sets of DIP switches accessible through the front panel. One set of switches determines whether the port is an input or an output. The other set of switches determines whether the input port is active high or active low. When used as digital outputs, the ports are currentlimited open collector outputs. In addition to the indicators, each input/output also has a frontpanel push-button switch, which allows local personnel to acknowledge or clear an alarm. Three ‘Relay Outputs’ are provided to enhance local interconnection of BAM’s that are operated in a stand-alone mode. Signaling protocols are based on AM’s OmniStat transponder communications protocols. An “F” connector is provided on the rear panel to support an optional RF communications interface. The RF interface is intended for applications where the unit will be located at a remote hub or node in an HFC distribution plant. A local Craft interconnect is provided on the front panel of the BAM for use with the Omni2000 Local control software. The BAM can be powered by any AC or DC voltage ranging from 24 volts AC to 50 volts DC. Operation from 115 or 240 VAC can be effected by use of an external low voltage wall transformer. The BAM is packaged as a 1.75” high rack unit. Detailed operation of the BAM is explained in AM Publication #TD.BAM9044.
