Chapter 2
This Diagnostic Function requires the RS-485 port of ADAM-5000E to
be connected to COM1 of host PC, and the RS-232 port of
ADAM-5000E to COM2 of the previous host PC or other PCs. Then
you should install software such as ComWatch or Hyperterminal and
so on to monitor the commands that are being issued and the subse-
quent responses from connected modules.

Flexible Communication Port Function
Connection(ADAM-5000E only)
The Flexible Communication Port Function prevents ADAM-5000E
from system glitches due to communication line problems.
This function enables simultaneous connections via COM1 and COM2
port of your host PC to the RS-232 and RS-485 port of ADAM-5000E
specifically. While working in conjunction with specific HMI software
(e.g. AFX, FIX) that offers COM Port Backup Function, ADAM-5000E
can circumvent failed communication on one port by switching to
another available port to continue program execution.
