    Dual IR tower output —Calum Tsang
   Here's a dumb question. Does anyone know if I attach two IR towers with a Y splitter on the serial port that both towers will transmit? I want to guarantee transmission across a playfield from two or more towers for this rtl10.1SP2 RobotSoccer (...) (22 years ago, 24-Jan-02, to lugnet.org.ca.rtltoronto)

   (...) Hi Calum, nice try, but you migth have some trouble. first the IR tower like any RS-232 equipment also transmit back to the computer, It migth work if you split only the signal going from computer to IR Tower the problem that migth arise is if (...)

        Re: Dual IR tower output —Ross Crawford
   (...) It'd be difficult - because the tower "powers down" after inactivity, the computer needs to "ask" it whether it's alive before sending data. And if it's not, no data will be sent. If you look at the firmdl & dll programs from legOS, you'll see (...) (22 years ago, 24-Jan-02, to lugnet.org.ca.rtltoronto)
   
        Re: Dual IR tower output —Calum Tsang
   (...) Okay, but I only want to send-the BBRC software only sends AFAIK, so I wonder if that's still an issue. What you're saying is that the tower interactive on initialization with the host PC-I wonder of this is the case with BBRC. Is the IR (...) (22 years ago, 25-Jan-02, to lugnet.org.ca.rtltoronto)
   
        Re: Dual IR tower output —Jeff Elliott
    (...) Another thing you might want to think about, if we've got a few extra IR towers around - really, you're just trying to improve the coverage of the transmission elements. A spare IR tower has a set of transmission elements. So.. what would it (...) (22 years ago, 25-Jan-02, to lugnet.org.ca.rtltoronto)

        Re: Dual IR tower output —Calum Tsang
   (...) No, I haven't had the fun of married life just yet :) But I'm not downloading with BBRC, I'm just sending out messages. Like, the Mindstorms Remote Control only sends, it's not smart enough to receive, right? This is the same thing as what (...) (22 years ago, 25-Jan-02, to lugnet.org.ca.rtltoronto)
   
        Re: Dual IR tower output —Chris Magno
   Just to show off my ignorance, i wonder if it is as simple as opening up the "box" and parallel 1 or 2 ir LEDs, off the main LED. YES i know that, that would be more current draw, and maybe the Tower circuit was not designed for that, BUT being a (...) (22 years ago, 25-Jan-02, to lugnet.org.ca.rtltoronto)
   
        Re: Dual IR tower output —Ross Crawford
   (...) Possibly. It would probably be better to drive something else off the main board (an opto-coupler or something) & run all the leds off that via a separate supply. Also, IIRC, the tower actually has 2 LEDs - something to do with reducing the (...) (22 years ago, 28-Jan-02, to lugnet.org.ca.rtltoronto)
