It is often convenient to be able to have a connector wired up for this purpose if fault-finding and service are to be undertaken with equipment using RS232. The loopback connections are useful on occasions for applications like self test.

The connections for the serial loopback connector are given below in tabular form for a DB-9 D-type connector using the common pinout connections.Р”ВB9 Connector Serial Loopback ConnectionsР”Р„ table showing the loopback connections when using a DB25 D-type connector using the common pinouts is shown below.Р”ВB25 Connector Serial Loopback Connections Although it may not be necessary to incorporate all the handshaking connections for all applications, they have nevertheless been incorporated so that the serial loopback connector should work for all situations. The connections given below form a commonly used configuration. There is more than one way to wire up a serial loopback connector. The loopback plug connects serial inputs to serial outputs so that the port may be tested. They can be made very easily either for DB9 or DB25 way connectors. RS232 loopback connectors are very easy to make up. However it will be able to test the basic functionality and provide a good level of confidence about the ability of the equipment to send and receive and generally check the operation of the serial port. The test loopback connector approach to testing has its limitations as it will not be able to detect speed mismatches or the like as the same issue is likely to be present on transmit and receive. In this way the equipment can be used on its own to check that it can communicate, even if it is only with itself. When testing RS232 links, it is often useful to have a test loopback connector.

WeРІР‚в„ўve got a whole tutorial on advanced screensharing for clip playback in Streamyard using VLC so be sure to check that out if you're going to use this audio loopback for Streamyard. VLC Player is a program that you can set audio outputs for independently which is extremely useful for screensharing video clips into Streamyard without messing up the rest of your sound. Instead, leave Zoom/Streamyard feeding directly to your headphones and set either the system overall, or the specific application youРІР‚в„ўre sharing, to output to that Multi-output device. This is because you would wind up sending everyone on the call their own audio right back on a slight delay and that will really mess with them. For one, youРІР‚в„ўre pretty much never going to want to set your Zoom or Streamyard speakers to that Multi-output device or to the VB-Cable directly. Connect L/R outputs on UMC404HD to Amplifier 6.35m inputs > 2 XLR to 6.35mm cables. Connect the Loopback connection on UMC404HD > Line input to Line Output > 6.35mm jack to splitter 2 x 6.35mm cable. So thatРІР‚в„ўs the bulk of it! There a few more issues to be aware of though. The following image is how i would configure everything: Connect Mic to UMC404HD (XLR to XLR) Connect Laptop to UMC404HD by USB.

ItРІР‚в„ўs called VB-Cable Virtual Audio and you can find the download page by clicking here. So letРІР‚в„ўs turn to a program thatРІР‚в„ўs free, works on Macs and PCs and installs safely with just a few clicks.

Soundflower has been the gold standard for years, but itРІР‚в„ўs Mac only and if you try to install it these days you have to override MacРІР‚в„ўs newest security guidelines just to trick it into installing. ThereРІР‚в„ўs even one thatРІР‚в„ўs actually called ' Loopback' but it costs quite a bit of money, so letРІР‚в„ўs ignore that one. ThatРІР‚в„ўs where installing a third party loopback application comes in handy. Streamyard also has a solution but it only works with Chrome tabs, so if you need to share sound from another program (like say Premiere for a tutorial!) youРІР‚в„ўre out of luck. Zoom has their own proprietary solution to this that auto-installs at the time that you install Zoom, but its actual quality isnРІР‚в„ўt fantastic. So letРІР‚в„ўs break it down.Р”Р‡irst, why would you need this? Well, anytime youРІР‚в„ўre screensharing content over services like Zoom or Streamyard that includes audio, youРІР‚в„ўll need loopback sound of some kind. It can wind up being a kind of tricky concept, but it has myriad uses, especially in the days of social distancing. This is the concept of virtualy routing the audio out from your computer directly to a destination without needing any cables or additional hardware.
