1. About
-----------------------

The Router connects two or more BACnet/IP and BACnet MS/TP networks.
Number of netwoks is limited only by available hardware communication devices (or ports for Ethernet).

3. Build
-----------------------

1. Download, build and install libconfig C/C++ Configuration File Library
   from http://www.hyperrealm.com/libconfig or use APT to install
   sudo apt-get install libconfig-dev
2. Run "make clean all" from library root directory
3. Run "make router" from library root directory

-----------------------
4. Router configuration
-----------------------

4.1. Configuration file format.

//single line comment

/*
    multiline comment
*/

ports =
(
    //route_1
    {
        device_type = "<value>";
        //route specific arguments, see below
    },

    //route_2
    {
        device_type = "<value>";
        //route specific arguments, see below
    },

    //.....

    //route_n
    {
        device_type = "<value>";
        //route specific arguments, see below
    }
);

Note:   - arguments are separeted with ';'
    - routes are separeted with ','
    - no ',' after the last route

4.2. Configuration file arguments.

Common arguments:
    device_type - Describes a type of route, may be "bip" (Etherent) or "mstp" (Serial port). Use quotes.
    device      - Connection device, for example "eth0" or "/dev/ttyS0"; default values: for BIP:"eth0", for MSTP: "/dev/ttyS0". Use quotes.
    network     - Network number [1..65534]. Do not use network number 65535, it is broadcast number; default begins from 1 to routes count.

bip arguments:
    port        - bip UDP port; default port is 47808 (0xBAC0).

mstp arguments:
    mac     - MSTP MAC; default value is 127.
    max_master  - MSTP max master; default value is 127.
    max_frames  - 1. Segmentation does not supported.
    baud        - one from the list: 0, 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400; default baud is 9600
    parity      - one from the list (with quotes): "None", "Even", "Odd"; default parity "None". Use quotes.
    databits    - one from the list: 5, 6, 7, 8; default 8.
    stopbits    - 1 or 2; default 1.

4.3. Example of configuration file.

    ports =
    (
        {
            device_type = "bip";
            device = "eth0";
            port = 47808;
            network = 1;
        },
        {
            device_type = "bip";
            device = "eth1";
            port = 47808;
            network = 2;
        },
        {
            device_type = "bip";
            device = "eth1";
            port = 47809;
            network = 3;
        },
        {
            device_type = "mstp";
            device = "/dev/ttyS0";
            mac = 1;
            max_master = 127;
            max_frames = 1;
            baud = 38400;
            parity = "None";
            databits = 8;
            stopbits = 1;
            network = 4;
        }
    );

5. Start
-----------------------

5.1. With configuration file
1. Copy configuration file in the router executable directory
2. Start the router with "sudo ./router -c init.cfg" command in terminal

5.2. Passing params in command line
1. sudo ./router -D "mstp" "/dev/ttyS0" --mac 1 127 1 --baud 38400 --network 4 -D "bip" "eth0" --network 1
