ok.. first let me start with this is not a hobby for me. I am a radio operator looking for some tech advice. I am using a program called eqso that is a voip program that makes it possible to inteface·a two way radio audio placing it on the internet, thus using the internet to transfer the voice to another location. I am using a box from www.ilinkboards.com and it works fine. All this box does is take the control formats from a 9 pin or com port and makes a relay close when there is voice traffic on the internet (vox) and with the relay it places the radio to ground making it key up and using the soundcard on the computer the voice is injected into the radio letting everyone hear that has the proper two way channel. My question here today is there anyway to make this BS2 take the commands from the com port so I can place a relay on the board letting me hook my radio to it and pulling a ground?

    This is possible but you will need to provide more detailed info. What are the control formats? Could you draw a circuit of what you have connected to where now and what you want from the stamp?

    I am trying to obtain the control formats now, unless there is a way to like read them or something. I am including a schematic of the ULI board that I am using, but keep in mind. I am only using the 9 pin from the computer all audio coming and going is from sound card and radio only.. nothing thru the 9 pin. it is only a control device that places the radio into ground for transmitt. the uli schematic wil show alot more uses, but are not being used by my project.

    here also is the eQSO program I am using. Open it and look at it, maybe someone can tell me what format the codes are and can help me write a program for stamps.

    This is what I get from the maker of the ULI board.

    Bobby, no idea. I have tried to communicate with the eqso people and never have gotten a response.

    When a signal is present on eqso, it sends a signal through the serial port to the pic chip on the ULI. This causes the relay to trigger. I am not sure why you need to know the exact code. I know it send a T for transmit and R for receive.

    You can key up the radio by pulling the push to talk line low with a basic stamp pin. It is best to use a 2n2904 transistor as a buffer. The pin will go low when the basic stamp is powerecd·up. So you use a basic stamp pin as output, a 1 k resistor to the base of the 2n3904. The emitter of the 2n3904 goes to ground and the collector goes to the radio push to talk line on the accessory port of the Maxtrac/CM200/CDM750 ect Pin 3. When the output pin goes high it turns on the 2n3904 transistor causing the push to talk·line to be pulled to ground through the emitter of the 2n3904jumpin.gif

    I am an odd duck, whent to Navy computer school in 1968 and went to work at a MRSS when I got out in 71 the Basic Stamp is my budy.

    It helps me automate all kinds of stuffburger.gif Let me know more about what you are doing, I do some VOIP stuff also. VOIP thats a TLA -

    Three Letter Acronym. I try not to use to many of them, soon no one knows what the hell you are talking about so I never use HETLA
