1. 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 CD-ROM.
*1 RS-232C 2ch communication module : COM-2(FIT)GY
Isolated RS-422A/RS-485 1ch communication module : COM-1PD(FIT)GY
*2 IEEE 802.3af-defined technology that supplies power from a LAN cable. PoE enables flexible layout, regardless
where the power supply is.
Features
Two types of power supplies available
RP-COM(FIT)H : Corresponding to the wide input power supply (10 - 30VDC)
RP-COM(FIT)H-AF : 5VDC and PoE supporting the use of IEEE802.3af-compatible devices,
enabling power to be supplied from UTP cables *1
Three operating modes selectable, depending on the usage
Virtual COM Mode : Can be used like the standard COM ports of a PC (max. 32 ports)
Through Mode : Can extend the distance between devices without changing settings or
applications of each device (max. 254 pairs)
Modem Mode : Creates communication programs capable of communications between
multiple terminals (N:N, max. 254 terminals)
Up to 7 channels available for RS-232C (when three COM-2(FIT)GY’s are added)
Add-on device modules [COM-2(FIT)GY] (for RS-232C 2ch) and [COM-1PD(FIT)GY] *2
(for RS-422A/RS-485 1ch) can be freely combined to allow up to three units to be added for extension

3. Explanation in Mode of Operation
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 CD-ROM.
*1 RS-232C 2ch communication module : COM-2(FIT)GY
Isolated RS-422A/RS-485 1ch communication module : COM-1PD(FIT)GY
CAUTION
- 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.

3. Explanation in Mode of Operation
Modem Mode
This mode creates a control program and uses a dedicated command to enable communication in
packets.
As packet data is transmitted with the corresponding Device ID, communication is possible between
multiple units of the product and stacked add-on module.
Up to 254 units can be installed on one circuit. However, communication is not possible between
devices connected to the product and stacked add-on device module *1.
Due to a command-based control used, dedicated applications are required on the devices to be
connected to the serial ports of the product and add-on module. Also, the type of data being sent or
received can be identified as either text data, binary data, Ethernet data, or UDP/IP data. In particular,
UDP/IP data can be used to communicate directly with a Socket interface on a host PC.
The following three types of communication are supported.
(1) Communication with a specified device ID
Communication can be performed between RS-232C (or RS-422A/RS-485) devices connected to
RP-COM(FIT)H, RP-COM(FIT)H-AF and add-on device module.
(2) Communications with UDP/IP Socket
This can be used to communicate with Windows PCs or workstations on the Ethernet.
(3) Build and transmit or receive Ethernet frames
This can be used to communicate with Ethernet devices that use a protocol other than UDP/IP.
The Device ID is set by the rotary switch on the main unit or the setup utility. Ensure that the
specified device IDs are unique
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.
Refer to Help in the bundled CD-ROM for the use of setup utility.
*1 RS-232C 2ch communication module : COM-2(FIT)GY

CAUTION
- Ensure that the specified device IDs are unique
- Device ID 255 is reserved for broadcasting.
- 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.

6. SNMP Agent Functions
This chapter describes the SNMP functions of this product, and explains how they can be built in using
the SNMP Manager SNMPc by CONTEC.
SNMPc Overview
SNMPc is network control software for SNMP that runs on Windows and controls all network devices
that have SNMP agent functions. SNMPc can be used to perform the following control functions.
- Monitoring unit startup status
- Monitoring port operating status
- Indicating MIB information
- Displaying log files of traps, events, etc.
For instructions on installing and operating SNMPc, refer to the SNMPc documentation. Note that a
bitmap display of this product can be displayed on SNMPc by installing it from the floppy disk provided
with this product.
MIB Support
This product provides MIB support for MIB-II (RFC1213) and private MIB. Support is provided for
the following group names.
Table 6.1. Group Names
MIB Group name Description
MIB-II
system Information related to AP, including AP control name, operating time etc.
interfaces Basic information related to the physical interface layer,
at Information corresponding to the ARP cache
ip Information related to IP protocol, including IP address information etc.
icmp Information related to ICMP protocol, including ICMP message TX/RX count, etc.
udp Information related to UDP protocol, including UDP message TX/RX count, etc.
snmp Information related to SNMP, including SNMP message count, etc.
Private MIB
rpcomhEnvironment Operating environment information.
rpcomhStatusInfo Status information including LED, DIP switch status.
rpcomhIfTable Interface data for Ethernet and RS-232C port

Control Using SNMPc
Install SNMPc on a personal computer in the network to which this product is connected. Read the
SNMPc manual carefully.
Once installation is complete, you can operate the PC on which SNMPc is installed as a network
manager, analyzing network status and error information from this device as shown below.
Also, you can install the Utility Disk provided with this product on SNMPc, to display information
about this product in graphic form as shown below.
CAUTION
In order to control this product, its IP address and community name must be entered accurately in
the Settings.

6. SNMP Agent Functions
Building-in to SNMPc
MIB data is embedded into SNMPc Ver.4 or Ver.5. SNMPc must be terminated when embedding the
data.
(1) Insert the attached CD in the CD drive.
Here, the D drive is used as the CD drive.
(2) Execute the “RPCOM_H.EXE” file in [D:\RPCOM\MIB\RP-COM(FIT)H\] or
[D:\RPCOM\MIB\RP-COM(FIT)H-AF\].
(3) Embed the data according to the procedure displayed on the screen.
MIB Database Updates
After installing a new vendor, you will have to update the MIB database the next time SNMPc is started.
Follow these steps to update the MIB database. In this description we use 'SNMPc Ver.5' as an
example.
(1) Start SNMPc.
To start SNMPc Ver. 5, select [Start] - [Program] - [SNMPc 5.0] - [Startup System].
(2) Click [Yes] to update the MIB database.
(3) When you are finished updating the MIB database, click [OK]. The build-in to SNMPc is not
complete.

7. Troubleshooting
7. Troubleshooting
This chapter describes common problems that may occur with this product and what to do about them.
If any problems occur that are not described here, check to confirm that the re-occur, then contact the
store where you purchased the product.
When Communication Fails
Check hardware
- Check that the LAN cables are connected correctly.
- Check that the serial cables are connected correctly.
Check software
- Was the unit started with the ID switch set to “F”?
- Is the ID switch set correctly (0 - E)?
- Is the MODE switch set correctly?
- Is the baud rate set correctly?
- Is the operating mode set correctly?
- Are the IP address and subnet mask set correctly?
When SNMP Connections Fail
- It is possible that the device cannot locate a control parameter, or that a private MIB has not been
compiled. See Chapter 6.
- If MIB settings have not been made, the correct community name may not have been entered. Be
sure the community name setting agrees with the network manager's setting.
- Check the SNMP settings that are being used.
When the RP-COM(FIT)H, RP-COM(FIT)H-AF Will Not Start
Check the power LED
- Be sure the power LED is on. If not, check that the AC adapter, power supply connector, and
mains power plug are connected correctly.
- If the POWER LED does not illuminate within 3 minutes of turning on the power or resetting via
the utility software, first check whether the device ID is set to “F”.
- If the device ID is set to “F”, change to a value other than “F”, then restart.
- If the device ID is not set to “F”, it is possible that the firmware is faulty.
In this case, use the utility software to update the firmware.
