Installation
The LTX board and wire antenna must be mounted in a non-metallic, non-
conductive enclosure. Note that some plastic enclosures have a metallic coating
applied to the inside for screening purposes, these would be totally unsuitable
and would result in severe attenuation or complete loss of signal strength.
See diagram below for positioning of the wire antenna. Care should be taken to
avoid strain on the soldered termination and other cables should be kept clear of
the antenna. Do NOT attempt to shorten, alter or replace the antenna. This may
severely affect performance and will void all warranties and Type Approvals.
Similarly, if using a metal-cased battery such as a PP3 style cell, avoid
positioning the battery next to the antenna.
The input trigger cables should be kept as short as possible (< 1mtr) and should
not be grouped with any other cabling (especially power, telecom and any data
cabling). Ensure that these are volt-free ("dry") contacts only. Applying voltage to
these inputs will irreparably damage the LTX unit.
Environment: note that where the transmitter is to be used in a non-temperature
controlled environment (e.g. an unheated outbuilding or outside), the enclosure
will need to be suitably protected from dust & moisture ingress (at least IP67
rated) and adequately protected to prevent internal condensation, which will
otherwise damage the LTX board beyond repair. The operating temperature
range of the LTX (see Specification section below) must also be observed.
