    2. Hardware Description The following information is provided to give the user an understanding of how to connect the TRP-C37M to the LAN and serial device. A review of the switch settings and the functionality of the LED’s are also provided.
  • Page 5 2-3. Power Input DC Jack: Power Input DC +10V to +30V. (Please use the 5.5*2.1mm DC JACK). There are two types power input. a. Use the plug of power adaptor than plug in the DC jack on the side. This approach also allows the user to provide additional power to other devices using the terminal from EU regulation.
  • Page 6 2-6. DB-9 Pin male pin assignment...
  • Page 7 The DB-9 serial port is DTE interface. A null modem cable is required to make a connection between the COM port on a PC and the TRP-C37M serial port. A straight through cable is required to connect the TRP-C37M serial port to a DCE device.
  • Page 8 Signals are single ended and referenced to Ground. To use handshaking, Flow Control must be set to RTS/CTS during Configuration. Refer to the Pin out table for connections. 4. How to configure TRP-C37M There are 3 ways to access the Server Properties and program the TRP-C37M. a.TRP-C37X DSM utility.

  • Page 11 4-1. Using TRP-C37X DSM Utility. The “TRP-C37X DSM” software performs several functions: A: Searching for TRP-C37M connected to the network. B: Displaying and changing the configuration of TRP-C37M. C: Upgrading the TRP-C37M firmware.
  • Page 12 D: Saving and Loading Configuration from external log File or EEPROM. 4-2. Searching LAN for TRP-C37M Once TRP-C37M is connected to the LAN the TRP-C37X DSM software will search it and display it in a window by name , IP address, Mac….Information.
  • Page 13 If DHCP is enabled ,the IP address, Subnet mask, Gateway address will be dynamically configuration by DHCP server such router. When “DHCP” is enabled ,but the DHCP server is not available on the network, the TRP-C37M will timeout then back to factory setting IP=192.168.1.1.
  • Page 14 LAN communications between Host PC Client and gateway devices. Maximum Connection: 1~16 The function allows the user to configure the TRP-C37M Serial Gateway to have up to 16 TCP client connections. TCP Keep Alive: 1~7 /Minute When TRP-C37M in Server mode, the TRP-C37M without data over the 1~7 Min setting value, The TRP-C37M will be disconnecting TCP.
  • Page 15 Upgrade the firmware 4-4 using the WEB Server mode The Web Server can be used to configure the TRP-C37M Serial Gateway from any web browser software (such as I.E). In Internet Explorer type the IP Address of the Serial Gateway into the address field and press the Enter key.
  • Page 16 Insert the TRP-Serial CD then find the CONSOLE.exe, The CONSOLE file support all windows O.S include MS-DOS, Run the CONSOLE file and Re-boot the TRP-C37M then select correct host COM port number and data format.
  • Page 17 TRP-C37M. The TRP-C37M actually can make connections with any Host IP, Once the user has filled in the Host IP, these IP are valid, the TRP-C37M will be pass with them. Other host IP will not pass. Refer to the following example illustrates.
