    Configurable biasing and termination for RS485 (DMX512) device

    Hello everyone! Long time lurker, first time poster on the forums, so lovely to meet you all. I am currently working on a relatively simple "adapter" circuit to incorporate Lumen Radio's TimoTwo DMX module. It's an integrated device that facilitates a wireless DMX512 link and a TTL level...

    Placement of Termination Resistor

    Dear Team, For series termination, we need to place the termination resistor close to the driver and for parallel termination, we need to place the resistor close to the receiver. what will happen if did not place it close to the driver/receiver and why? Regards Hari

    Termination for Differential Pair - 50 ohm transmission line

    Hi, I have a circuit (see attached) and I am wondering what happens to a differential signal that gets generated in U1 and received by U2. Lets say the signal has a 400-600mv swing at the output of U1. Would I see the following at U2? Vout = R2/Rs+R2 * Vin : Vout= 50/10+50 * 600mV =...
