The CPU (central processing unit) module houses the multi-layer PCB,
which contains the ControlWave CPU, I/O monitor/control, memory,
and communication functions. It also may include the optional
Secondary Communications Board (SCB).
The CPU module includes:
 AMD Elan SC520 microprocessor running at 100 MHz
 two RS-232 communication ports
 one 10/100baseT Ethernet port
 2 MB of battery backed Static RAM (SRAM)
 64 MB of Synchronous Dynamic RAM (SDRAM)
 512 KB boot/downloader FLASH
 32 MB simultaneous read/write FLASH memory
 transmit (TX) and receive (RX) LEDs for each communication port
 Keyed run/remote/local operation switch
 configuration DIP switches (described in Chapter 2)
 Port 80 display to show status codes
You can order the CPU module with the optional secondary
communication board (SCB) for additional communication ports. See

CPU Module Configurations.

The CPU module has several basic configurations, all of which have an
on-board backup battery and different combinations of
communications ports.
