    System Overview

    TMN-51T is a plug and play RS232 to GPRS gateway. It can easily retrofit a traditional

    serial communication system to a more advance GPRS platform. Remote devices can be

    centrally managed without upgrading the device firmware and central software. Unlike

    those systems that the devices are centrally managed via PSTN or GSM dial up line or

    lease line, TMN-51T can be a more cost economical solution to achieve an “always on”

    data link network.

    Note: TMN-51T may be able to use with 3G SIM card/data plan seamlessly but subjected

    to Telco‟s offering.

    Hence, our customers may enjoy the economical 3G data plan for higher data bandwidth

    package.

    TMN-51T (RS485 interface)

    For TMN-51T with RS485 interface, a RS232 to RS485 converter is necessary to convert

    the signals from TMN-51T into RS232 standards that are recognized by the PC.

    Connecting TMN-51T to Device

    TMN-51T (RS232 interface)

    For a basic configuration in which TMN-51T is connected to a device via RS232 port,

    transmit, receive and ground pin must be connected. In situation where the device is

    utilizing hardware flow control, Ready To Send (RTS) and Clear To Send (CTS) have to

    be connected as well. TMN-51T with RS232 interface supports hardware flow control.

    For TMN-51T with RS485 interface, max of 32 remote devices can be connected.

    TMN-51T Analog Inputs

    TMN-51T supports 2 channels of 4-20mA analog inputs. The 2 analog inputs are located

    at the 4 pin Micro Fit 3.0 power supply socket as shown in Figure 4 below.

    Figure 4: Analog Inputs

    To insert the analog signal to TMN-51T, use TMN-51T power adaptor‟s 4 pin Micro Fit

    3.0 socket connector as shown in Figure 5. The additional 2 empty holes are for the

    analog input.

    Hyper Terminal Communication We will be able to configure TMN-51T by connecting it through RS232 cable to an

    available comports as seen in Figure 6. This process does not require the Center Manager

    software.

    Figure 6: Connecting TMN-51T to a PC Hyper Terminal

    In Windows7 PC, by default Hyper Terminal is not available; however, you can create

    it by:

    Opening any Window Xp system and copy the following four files:

    1. C:\Program Files\Windows NT\HYPERTRM.EXE

    2. C:\Windows\Help\HYPERTRM.CHM

    3. C:\Windows\Help\HYPERTRM.HLP

    4. C:\Windows\System32\hypertrm.dll

    Open Windows 7 system and create a folder name of “HyperTerminal" under program

    files then paste the four files copied earlier.

    Create shortcut for "C:\Program Files\HyperTerminal\HYPERTRM.EXE" and the

    Hyper Terminal is ready.

    The steps to configure the device using Hyper Terminal are shown below.

    Configure TMN-51T

    Plug in the SIM card to TMN-51T.

    Check the Antenna was connected properly.

    Check the Power Supply was connected accordingly.

    Power on TMN-51T after Hyper Terminal is connected.

    Open the Hyper Terminal, Use 115200, 8N1, No flow control.

    After pressing space for 3 times immediately after power on, it will give the

    indication and enter “tcam” as password.

  • TMN-51T Hardware User Guide 11

    After the correct password was typed, it will show the main configuration menu.

    The Mobile Network Operator Setup, please check with the network operator‟s internet setting.

  • TMN-51T Hardware User Guide 12

    In the TMN51 Device setting,

    o Device ID is required,

    o Max Package Size was set to 1250 for this case.

    o Packet Idle Interval will leave it as 5 which is the default value

    o Please remember to Set correct Packet Idle Interval for different baud rate

    Recommend 5 ms for 115200

    Recommend 100 ms for 300

    The value should be adjusted to app requirement

    o Packet End Character is disabled when Packet Idle Interval is not “0”.

  • TMN-51T Hardware User Guide 13

    In the DSC setup

    o Server IP Address is refer to the public IP of the PC server.

    o Communication Protocol is set to 4 (UDP APP client) in this example

    o Online Report Interval is set to 150 in this example.

    o Communication port is set to 8000 (or any number which you can get for public internet access, please make sure it is the same with the one which is used on Server port.

    Please make sure this port can be accessed from internet. Either the server is direct open to the public network or the port is forward to the public network. Please consult the IT administrator for this.

    o Backup Server IP Address, Center Phone Number is not used in this example.

  • TMN-51T Hardware User Guide 14

    Serial port Setup

    o Baud rate can be set from 0~8,

    8: 115200, 7: 57600, 6: 38400, 5: 19200, 4: 9600, 3: 4800 2:2400 1:1200 0: 300

    Please remember to Set correct Last packet Idle Interval for different baud rate

    Recommend 5 ms for 115200

    Recommend 100 ms for 300

    The value should be adjusted to app requirement

    o Flow Control can be set as Xon/ Xoff, Hardware or None.

    o The TMN-51T will always goes to 115200, 8N1 after power on. After no correct control command is received, it will goes to the GPRS gateway mode as configured.

  • TMN-51T Hardware User Guide 15

    After all the parameter was set correctly, please go back to main menu and press „7‟ to save the parameter , then press „9‟ to restart the TMN-51T.

    After reboot, and wait for a while without any input, the TMN-51T will go to Data mode. It will also display all the major configuration info except the ID info (for secure reason).

    After the TMN-51T get the IP address from network, it will display this IP info before it switch to the working serial port setting (before this, TMN-51T is always

    working in the control mode with 115200, 8N1 setting).

  • TMN-51T Hardware User Guide 16

    Just right after the Local IP address is got, the Server side should receive login info.

    If the TMN-51T cannot get IP address from network operator, it will reboot itself after few attempts. From HyperTerminal, you can find this reboot. Please check the APN setting, User Name and Password in this case.

    If you select the TCP protocol and server is not ready, The TMN-51T will also reboot itself after trying to build TCP socket failed for few times. Please do

    checking the correct protocol and correct port setting is used from both VSP and

    TMN-51T side. From HyperTerminal, you will see the reboot after “Local IP

    address:…”. This is different from the previous reboot (cannot get IP address).

    If the server is down, the TMN-51T will also reboot itself after TTL timer expired (as it cannot identify whether it is caused by Server Down or Network lost signal).

    The TMN-51T will ping to the server and confirm the connection by the Ping

    echo. If the server (router) does not reply this Ping, the TMN-51T will consider

    the connection is failed as well. So, make sure your server or router is configured

    accordingly.
