I am providing minor source code mods here and  pointers to documentation
for the TRIPMATE that will allow people to use the unit on ROCKWELL binary mode. The
TRIPMATE is a fully functional rockwell zodiac based receiver. I found that
you can order the Rockwell Zodiac Starter Kit Documentation set and Disk
from  TDC, see: http://www.tdc.co.uk/jupiter.htm . The also sell starter
kits and other useful things. (Note their BBS in ONLY available to customers)

Once you order the disk add the following code to the LABMON.C source file:


Method one: (This automatically detects the GPS and switches to Rockwell
Binary Mode )

    At the start of main()  add the line
            int chk_astral;

    Still in main() find the line:

          if(!have_sync) {

    add the lines:
                if(!chk_astral) {
                    if(bytein == 'A') {
                        while(get_byte() != '\r')
                            ;
                            (void) init_zodiac();
                            ++chk_astral;
                    }


Method two:
    At the very end of the function process_kbd(KeyboardType kb)

        add the lines
           case aF10:
                (void) init_zodiac();
              break;



Add the new function:


void void init_zodiac()
{
      send_raw("ASTRAL\r");
      wait(3.0f);
      // set labmon message protocol
      DataType = Z_BINARY;
      clear_screen();
      clear_message_line();
    _outtext("LABMON MESSAGE PROTOCOL SET TO ZODIAC BINARY");
      wait(.5f);

        // gpsirq  == IRQ
        // gpsbaud = 4800 , BAUD
        // gpsprty == PARITY, N,O,E
        // gpsnbit == BITS, 7,8
        // gpssbit == STOP, 1,2

        DataStream   = 0;  // will be ignored
        ProtocolType = 0;  // force binary
        send_raw("$PRWIIPRO,0,RBIN\r\n");
        wait(1.5f);

        clear_message_line();
        _outtext("RECEIVER MESSAGE PROTOCOL SET TO ZODIAC BINARY");
        wait(1.5f);
        init_time(0);
}

void send_raw(char *str)
{
    while(*str)
        send_byte(*str++);
}
