commands will be covered in Chapter 6.
Flexible Communication Connection
ADAM-5000’s built-in RS-232/485 conversion capability enables users
to freely choose either RS-232 port or RS-485 port to connect with host
PC. When user select either port to connect with their host PC, the
other port could be utilized according to their specific needs.
For example, if RS-232 port is selected for connection with host PC,
the RS-485 port can be used for connection with DA&C modules (such
as ADAM-5000/485, ADAM-5000, ADAM-4000 modules). Thus users
save extra costs for another RS-232/485 conversion device (e.g.
ADAM-4520).
Or if users select RS-485 port for host PC connection, the RS-232 port
can then have different usage such as described in the following
sections (see Built-in Communication Ports for Field Diagnostics and
Flexible Communication Port)
Built-in Communication Ports for Diagnostics

(ADAM-5000E only)

When users utilize application software to control their system,
ADAM-5000E can provide another port to let user monitor at any time
the communication quality and condition as a reference to mainte-
nance and test. When error occurs in the system, users can perform a
quick diagnostics to locate the fault. A considerable amount of
troubleshooting efforts can be saved. For example, using popular
ComWatch software, users can watch the current execution and
response of a certain command. It is very convenient to identify
whether it is communication or the hardware product that is causing
the problem.

Flexible Communication Port(ADAM-5000E only)

ADAM-5000E provides a further application. Users can simultaneous-
ly connect COM1 and COM2 of host PC to RS-232 and RS-485 port of
ADAM-5000E. When host PC issues a command through one of the
COM ports but receives no response (the other port will serve as
backup), the COM Port Backup Function of HMI software (e.g. AFX,
FIX) will automatically switch to another COM port to continue
