2.4.3 Connections to RS-232 Serial Port(s) on CPU or ECOM
Modules
An RS-232 port provides point-to-point, half-duplex and full-duplex
communications (for a maximum of 20 feet using data quality cable).
Your CPU module includes either one or two RS-232 ports.
If you require additional RS-232 ports, you can purchase an optional
expansion communication module that can include either one (ECOM
Type 1) or two (ECOM Type 2) RS-232 ports. The ControlWave Micro
can support up to two expansion communication modules, for a total of
up to four additional RS-232 ports beyond those on the CPU module.
Expansion communication modules reside in slot #3 and slot #4.
RS-232 COM
Port Names and
Connectors
RS-232 COM ports are assigned names based on their location in the
ControlWave Micro.
If the CPU module has two RS-232 ports and one RS-485 port (as in
Figure 2-13), the RS-232 ports are COM1 and COM2.
If the CPU module has one RS-232 port and one RS-485 port (as in
Figure 2-15), the RS-232 port is COM1.

If you have an ECOM module with one RS-232 port, this is COM4
if the module is in slot #3 or COM8 if the module is in slot #4.
If you have an ECOM module with two RS-232 ports, those ports
are COM4 and COM5, respectively, if the ECOM module is in slot
#3, or COM8 and COM9, respectively, if the ECOM module is in
slot #4.
