    Is it possible to connect 2 PCs to another device using a splitter cable.

    At the moment, the device sends a string of characters, approx 20, to a PC
    at 19200bps. The PC sends no information back. Could I simply make a
    splitter cable and connect the 2 PCs to this device, or would this degrade
    the signal or make it unusable in any way.

    Thanks.
     
  2. Yes, generally.
    Should be OK as long as cables are not too long. The load will be a
    bit higher, but should not matter unless you are already on edge of
    reliable operation.

    Have you ever used a question mark.

    With one transmitter and two receivers, yes, but don't tie two
    transmitters together.

    Hope This Helps!

    You need to ensure that the only lines which are used are those which are
    outputs on the device and inputs on the PC, i.e. TxD on the device, RxD on
    the PC. Do not "combine" output lines from the two PCs; you can't use TxD
    or RTS, so you cannot use flow control (you shouldn't need it).

    IOW, the cables should be two wire, with just device-TxD-to-PC-RxD and
    ground. If the device needs the flow-control lines active, connect CTS and
    RTS together at the device end.
     
  5. What you need is called a null-modem cable.

    No, he does not; "The PC sends no information back."

    He just wants to broadcast the signal to two computers.
     
  7. OOPS! Sorry, you're right.
