Before Using the Product
This chapter provides information you should know before using the product.
About the Module
RP-COM is a media converter that converts serial communication (RS-232C) to Ethernet
communication. It allows the cable distance to be extended from the limit of the serial communication
cable length (15m) to the Ethernet cable length as well as wiring to be reduced. Moreover, RP-COM
has three different operating modes: the Penetration Mode and Modem Mode in addition to the Virtual
COM Mode, used as the standard COM operating mode.
This product is upwardly compatible with the current RP-COM(FIT)GY. Stacking an add-on device
module *1 with the product enables more channels to be available (RS-232C) and also more functions
to be extended (RS-422A/485).
It supports wide input power supply (10 - 30VDC), allowing two types of power supplies (5VDC and
PoE *2) to be selected depending on the usage and environment.
Please read this manual carefully before performing system configuration such as setting switches or
connecting to external devices. For information about how to use the software, refer to the Help
section on the attached Disk.

(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.

RP-COM(FIT)H, RP-COM(FIT)H-AF
Through Mode
In this mode, data is transferred without any change from a connected device.
A serial cable used for one-to-one connection of devices can be converted to Ethernet connection
without any changes. In this way, two units must be installed as a pair for the product and stacked
add-on device module*1. Up to 254 pairs can be installed on a single circuit. However,
communication is not possible between devices connected to the product and its stacked add-on device
module.
Existing applications that operate using RS-232C (or RS-422A/485 : when expanding
COM-1PD(FIT)GY) can continue to be used without any changes.
The Device ID is set by the rotary switch on the main unit or the setup utility. For the rotary switch,
the same value is set to the Device ID. For the setup utility, the device ID of the party on the other side
of the connection (other party’s Device ID) can be set.
It is also necessary to match the serial parameters of the serial devices to be connected to the product
and its stacked add-on device module by using the setup utility.
For information about how to use the setup utility, refer to the Help section on the attached disk.
*1 RS-232C 2ch communication module : COM-2(FIT)GY
Isolated RS-422A/RS-485 1ch communication module : COM-1PD(FIT)GY
- If using broadcasting, ensure that all RP-COM(FIT)H (or RP-COM(FIT)H-AF) units have different
device IDs.
- Device ID 255 is reserved for broadcast use.
- To avoid any adverse effects on other LAN devices, set the IP address, subnet mask, and other
network parameters to appropriate values.
- Although, existing application can generally continue to be used unchanged, note that they may not
operate correctly if particular RS-232C control procedures are used (see below).
(Example) - Baud rate changed during operation
- Hardware signals used for proprietary purposes other than flow control
- RI signal used
- When COM-1PD(FIT)GY is stacked with RP-COM(FIT)H or RP-COM(FIT)H-AF, half duplex
communication is disabled.
