The Central Processing Unit (CPM2)
The Central Processing Unit (CPM2) controls the operation of the receiver. The CPM Unit incorporates two serial ports, a high-speed USB port, and an Ethernet interface for computer connection and one parallel printer port. The CPM Unit has two external inputs, one for external acknowledge, and one for tamper recognition. The CPM Unit also incorporates two programmable outputs, which can be programmed to follow different receiver status.
The CPM Unit features a 2000-event non-volatile memory buffer. The contents of the buffer may be browsed on the LCD screen. If the printer or computer is off-line, the CPM2 Card will store the incoming events in its buffer, and will automatically forward them, when the connection restores.
The CPM2 controls the large graphical LCD display of the receiver, which enables it to implement unique, user friendly features like changeable display font sizes, full line card control, and easy-to-use manual programming.
