SC Controller Circuit Boards (Intelligent)
BJH Intelligent
Controller Board Contains the microprocessor, memory, real time clock, serial interface,
and interface circuitry to the other intelligent circuit packs. Enables
“intelligent” features, including alarm history, battery reserve time
prediction, peripheral monitor and control, etc.
Also provides access to the TL1/X.25 interface.
BJJ1 or BJJ2
Power Boards Provides power to the intelligent controller board and intelligent option
boards.
BJJ1 is for 48 volt systems; BJJ2 is for 24 volt systems.
BJK1 Data Switch Operates the Data Switch, an optional interface with XCS, ECS, RAS,
and OMNIpulse units. Data Switch allows call-in and call-out access to
as many as four RS-232 devices via the Galaxy access ports.
BJL2 Modem
Board Required for data access over telephone lines. Provides the modem
circuitry needed to interface the controller from a remote location over
the switched telephone network at up to 14,400 baud.
BJM1 Peripheral
Monitoring Board Required for any peripheral monitoring or control. Provides interface
circuitry for up to 255 remote monitoring modules, allowing
connections to as many as 1,530 monitoring points.
SCF Controller Circuit Boards
The following figure shows the location of the Basic and Intelligent
circuit boards in the SCF Controller, which are described in the
following pages.
