{{other uses|Lanc (disambiguation)}} '''LANC''' ('''Logic Application Control Bus System''' or '''Local Application Control Bus System'''), also known as '''Control-L''' is a hardware and software communication protocol invented by Sony that synchronizes cameras.<ref>{{cite web|title= Sony Glossary terms |url=http://www.sony.com.au/support/glossary/index.jsp?letter=L&categoryId=21636 |work=www.sony.com |accessdate=2006-07-24 |archiveurl = https://web.archive.org/web/20060831211023/http://sony.com.au/support/glossary/index.jsp?letter=L&categoryId=21636 |archivedate = 2006-08-31}}</ref>
The LANC terminal on Sony and other manufacturers' camcorders lets accessories, such as tripods with a control handle, control the camera over a cable connected to the LANC port instead of using buttons on the camera. It is also available on many still cameras, where it is called ACC (the Sony DSC-xxxx series of cameras).
The bi-directional protocol is made up of 8 (8-bit) bytes, usually clocked by the camera at 9600 bit/s. Each frame of bytes occurs in sync with the beginning of each video frame (NTSC or PAL). The physical connector is either a 5-pin mini-DIN connector and jack<ref name = "Sony-LANC" >{{cite web | title = Sony LANC interface pinout | publisher = PinOuts.Ru | url = https://pinouts.ru/DigitalCameras/sony_lanc_pinout.shtml }}</ref> or a 2.5mm 3-conductor phone jack and plug (TRS connector).<ref name = "Sony-2.5" >{{cite web | title = DVin Lite, LANCTerm, RM95 interface cable | publisher = PinOuts.Ru | url = https://pinouts.ru/DigitalCameras/sony_lanc_cable_pinout.shtml }}</ref>
In newer Sony digital Handycam camcorders with 10-pin multi-A/V remote terminal jacks, LANC is available, but not directly accessible without making a home-made adapter cable or a pre-made cable by Sony Part# J-6082-535-A. Sony RM-AV2 Remote Commander is an example of a LANC controller that plugs into the Sony 10-pin multi-A/V remote terminal jack.<ref name = "Sony-RMAV2" >{{cite web | title = RM-AV2 Remote Commander | publisher = Sony | url = http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&productId=8198552921665304384&tab=Features }}</ref>
Starting with the 2015 model year, Sony has switched to a special 15 pin multiport connector that looks similar to a USB connector. However, it has 15 pins inside the connector, where a USB connection has 5. Currently, only the Sony VPR-RM1 controller works with Sony camcorders from 2015 and newer.
Sony "Control-S" is a similar interface, but is uni-directional, providing control-only, and not feedback from the controlled device.
Panasonic Control-M is a similar 5-pin mini-DIN bi-directional interface and protocol with a different implementation.
