Installing The Lattice System; Identification Of Terminals - Centsys Lattice Installation Manual

Installing the Lattice System

Installing the Lattice System
The L1000 can be installed in three different configurations:
as a stand-alone head
as a stand-alone head, but linked to a computer via a Take Up Head (TUH)
as a fully networked system using up to 31 Lattice Slave Head (LSH's) and a TUH.
Before connections are made to the unit it is necessary to identify the terminals of the various units and
their functions.

Identification of Terminals:

The following sketches show the location of the terminal blocks on the L1000 and slave head (LSH)
printed circuit boards (PCB's). The reader must be configured for either steel or masonry/wood
mounting. Incorrect configuration will result in poor read range or unreliable operation.
