2.4 CPU Module
The CPU module, which controls the ControlWave Micro and handles
memory and communication functions, can only be installed in Slot #2
of the ControlWave Micro backplane.
Note: Do not confuse the CPU module (which has communication
components) with the Expansion Communication module
(ECOM), which does not have a CPU component or a battery
backup but does have additional communication components.
Identify the carton holding the CPU module and remove it from that
carton. The CPU module has several different configurations, each of
which have on-board communications components:
 CPU with two RS-232 serial ports, and one RS-485 serial port (see
Figure 2-13)
 CPU with two RS-232 serial ports, one RS-485 serial port, and one
Ethernet port (see Figure 2-14)
 CPU with one RS232 serial port, one RS-485 serial port, and two
Ethernet ports (see Figure 2-15)
