LANC is a Sony protocol/standard that is mainly supported in equipment from Sony, Canon, and a few others. (e.g., some Videonics and Pinnacle products have supported LANC for edditing as well as the zoom controllers from a number of companies offered for camcorder control). LANC is based on a highly structured 9600 bps serial data stream, but it is not serial as implemented in the RS-232 port found on a typical PC. IT is based on a master and a slave unit.
At one time you could buy a copy of the LANC specification from Sony. Interesting reading if you are technically incline. It was developed as a means of controlling a wide range of consumer electronics, but mainly is found in consumer/prosumer camcorders and a few VCRs.
JVC and Panasonic do not have a history of suporting LANC. The schematic at the site you reference does NOT come even close to what is needed to do LANC control of a XL1 series camcorder. The text of the site even says that it is much simpler than LANC, and has limited functions compared to LANC.
I would not try it due to the risk of damaging the LANC controller chip in the XL1s. (The On/OFF button shorts the DC power from the LANC jack, and the potentiometer could short the serial data to ground as well.)
