10. Setting up VCOM-LAN for serial communications
(only REX 250)
In order to be able to use a remote connection to access serial participants, start
shDIALUP and activate the corresponding settings for the virtual COM port on your
computer. To do this, please click on the Tools button before logging in.
Deactivate the “inactive” check box in the “virtual COM port settings” tab.
The system will automatically suggest a network port and the COM port to be used,
neither of which need to be changed. Close the window by clicking on ”OK”.
You can then use your login information to log in to the portal server (see page 6,
chapter 3.1) and establish a connection to a REX 250 that has already been config-
ured (see page 14, chapter 6).
You receive further information by activating the VCOM-LAN status button.
In this example, the COM4 connection is now also available in the system in addition
to the standard remote maintenance connection. The possibility for serial communi-
cation is still indicated in the task bar by a green symbol (an active connection with a
yellow symbol).
