Model SCS-150 Receiver Processor Board
Description
The SCS-150 is the main system processor for the SCS-1R Security Control Receiver and controls the line cards, the LCD display, the printer (if used), and data output to a host automation system. The SCS-150 contains the software for system operation, the line configuration, and all time keeping functions. Programming can be done from the front panel of the SCS-1R Receiver or via Remote Link version 1.47 or higher.
Compatibility
The SCS-150 is compatible with the SCS-100 Dialer Line Cards and the SCS-101 Network Line Card using Level E hardware with Version 200 or higher software.
Line Card Slots
The SCS-150 Receiver Processor Board has a port (J6) for a line card connector and has five cables to support single dialer or ethernet cards. Slide the Line Card Cable Connector onto the J6 port on the SCS-150. Connect the line card cables to the existing line cards.
Communication Output Ports
The SCS-150 receiver has three ports to use for peripheral communication. The A1 port is used for printing to the Activity Log, the A2 port is for programming using Remote Link, and the A3 port is used as a host automation output port.
SCS-150 LEDs
1)Far Left LED: Flashes constantly. This is the heartbeat LED.
2)Center Left LED: On when the SCS-1R is saving data, such as programming changes.
3)Not used.
4)Far Right LED: On if memory resources are ever too low, such as thousands of messages pending at the LCD display or the printer.
