Field equipment deployment Inserting a blaster into a line (LSI and HSU) Inserting a blaster into a line (LSI and HSU) The LSS (Line Shooting System) allows you to use the 428XL telemetry network rather than a radio link to synchronize a remote shooting system with the recording truck, for example in situations and over stretches of land where radio communications are difficult. Shooting with an LSS does not require any audio communications between the observer in the recording truck and the shooter. The LSS consists of an LSI unit associated with an HSU. • The LSI (Line/Source Interface) allows you to connect a blaster controller along an acquisition line instead of connecting it to the control unit’s Blaster connector. It acts as a remote Blaster connector. • The HSU (Hand-Shake Unit) is used by the shooter to supply the status of the firing device and the number of the corresponding shot point to the central unit. 7 All types of extensions are still allowed where an LSI is used (LRU relay, Fiber Optics Link, Laser Link).
