This is an unique MAC (Media Access Control) address used by Ethernet in hex format, 6 digits.
Password:
This field is the administration password for authentication. Factory default is empty. However, it
is not recommended leave it empty in field operation.
TRP-C36 uses the same password protection mechanism commonly used in Windows NT
or UNIX. If there are more than 3 consecutive times failure in password check during the
login process, the login function will be disabled, even if user supply correct password,
the login will not proceed. This prevents intruders find password by computer to generate
program. User may revert TRP-C36 to factory default by pressing reset button, and login
again.
5-1. Start to Setup
After successfully login, the setup page will be shown as following:

1. Turn off the power of TRP-C36 device.
2. Press the reset button and hold..
3. Turn on the power (DC Jack) of TRP-C36 device.
7. Firmware Upgrade
As TRP-C36 firmware always keeps on enhancing with latest technologies and network
standards, if your applications need the latest release of firmware, you will receive a Win32
executable software to upgrade the firmware in TRP-C36 through network:
Connect TRP-C36 device to LAN. Firmware upgrade of TRP-C36 will not work on Internet.
Set the target TRP-C36 device to have IP address in the same subnet as your host computer.
In the DOS Prompt environment of Windows, execute the upgrade software you received with
target TRP-C36 device IP address as the optional parameter. If you omit the target IP address,
the upgrade software will try to find one automatically.
The upgrade will start immediately with percent finished display on screen. Wait until 100%
complete. Please note during upgrade, do not stop the software or remove the power of
TRP-C36 devices, it will cause permanent damage of firmware and can not be recovered.
8. Application

The TRP-C36 Ethernet serial server connects RS-232, RS-422 or RS-485 serial devices to an
Ethernet LAN/WAN providing a reliable communication connection. The TRP-C36 Windows
driver installs virtual COM ports in the Device Manager of the operating system. The virtual COM
port is designed to establish a connection with the TRP-C36. This in turn will allow
communications with the connected serial device in the same manner as a device connected to
the COM port in a PC. The LAN becomes transparent to the serial device and the software
running on the PC. TRP-C36 also offers a Heart Beat feature to insure a reliable communications
connection.
The TRP-C36 can be configured as a TCP Client/Server or UDP. The TRP-C36 operates in
“Paired Mode“, “Virtual COM” Mode”, and “Direct IP Mode”.
8.1 Paired Mode
Paired mode is also called serial tunneling. When this type of configuration is selected, No
additional software is needed to install in a host PC. In fact a PC is not required to make the
connection. Any two dumb serial devices that can communicate with each other through a serial
link will be able to communicate using two TRP-C36 and the LAN.
Two TRP-C36 are configured with one setup as a TCP or UDP client and the other to TCP/UDP
server. When setting up the Server, the Remote IP address section must contain the address of
the Client. This will allow the Client’s IP address to pass the IP address-filtering feature of the
Server. Conversely, the Remote IP address of the Client must contain the Server’s IP address.
How to Setup TRP-C36 paired mode
1. Configure TRP-C36 server.
IP address : 192.168.0.106 (for example)
Socket port of serial I/O: Port 1001 ,TCP Server
Socket port of digital I/O: port 101 , TCP Server

2. Configure TRP-C36 Client.
IP address: 192.168.0.109 (for example)
“TRP-C36 Client IP address must be different from TRP-C36 Server IP address”
Socket port of serial I/O : 1001, TCP Client.
Socket port of digital I/O: 101, TCP Client
Destination IP address/Socket port (TCP client and UDP): 192.168.0.106, port 1001.
The Client Destination IP address must be same as Server IP address (192.168.0.106), the
Socket port number must be same as Server Socket port number” (1001)
8.2 Virtual Com Mode

The Virtual COM mode requires the installation of a virtual COM port device driver. In this mode,
the TRP-C36 must be set to either TCP/server or UDP/server in the menu with a designated
communication port number.
The virtual COM driver is a TCP or UDP client. Once the connection is made, the LAN is
transparent to the serial device. Applications work just as if the serial device is connected a
host’s physical COM port. The virtual COM port converts the application’s data into IP packet
destined for the TRP-C36, which in turn converts the IP packet back to serial data. Point # 9 will
guide you setup Virtual COM mode.
8.3 Direct IP Mode mode
Direct IP connections allow applications using TCP/IP or UDP/IP network socket programs to
communicate with the asynchronous serial port on the TRP-C36. In this type of application the
TRP-C36 is configured to TCP or UDP server. The socket program running on the PC
establishes a communication connection with the TRP-C36. The raw data is sent directly to and
from the serial port.
“TRPCOM Test Utility” is demo utility which may help to test direct IP Mode .User may find
the utility in the TRP-C36 disk. Double click “Trycom Utility”, the installShield Wizard will guide
you complete installation.
