'''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](/source/Sony) that [synchronize](/source/synchronize)s [camera](/source/camera)s.<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](/source/NTSC) or [PAL](/source/PAL)). The physical connector is either a 5-pin [mini-DIN](/source/mini-DIN) connector and jack<ref name = "Sony-LANC" >{{cite web

In newer [Sony](/source/Sony) digital [Handycam](/source/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](/source/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

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](/source/Sony) "Control-S" is a similar interface, but is uni-directional, providing control-only, and not feedback from the controlled device.

[Panasonic](/source/Panasonic) Control-M is a similar 5-pin [mini-DIN](/source/mini-DIN) bi-directional interface and protocol with a different implementation.
