3. Explanation in Mode of Operation
Virtual COM Mode
This mode allows the serial ports of the product to be controlled via Ethernet from the attached virtual
COM driver for Windows.
Up to 32 channels can be used between this product and the stacked add-on device module *1.
Applications already in operation and using RS-232C (or RS-422A/485 when adding
COM-1PD(FIT)GY) can be used without any changes.
Use of the setup utility enables to set the product and add-on device module. For information about
how to use the software, refer to the Help section on the attached CD-ROM.

(Example1) RP-COM(FIT)H can be used like "COM3 of the PC via Ethernet.
* It is same when RP-COM(FIT)H-AF is replaced to RP-COM(FIT)H.
(Example2) COM-2(FIT)GY can be used like "COM3", "COM4" and "COM5"
of the PC when stacked with more than one RP-COM(FIT)H via Ethernet.
* It is same when RP-COM(FIT)H-AF is replaced to RP-COM(FIT)H
and when COM-1PD(FIT)GY is replaced to COM2(FIT)GY, too.

CAUTION
- When using the virtual COM driver on Windows 98/Me, COM ports cannot be extended by using
an add-on device module that is stacked with RP-COM(FIT)H or RP-COM(FIT)H-AF.
- To avoid any adverse effects on other LAN devices, set the IP address, subnet mask, and other
network parameters to appropriate values.
- When COM-1PD(FIT)GY is stacked with RP-COM(FIT)H or RP-COM(FIT)H-AF, half-duplex
communication is disabled.
