1 Introduction
The
ViaLite
Serial Digital Fibre Optic Modem is a family of fibre optically coupled link systems
designed for the Full Duplex transmission of DC Coupled RS422/485/232 and TTL signals over long
distances in electrically noisy environments.
This handbook covers the following
ViaLite
Serial Digital Fibre Optic Modem part numbers:
•
Modem units with part numbers starting LSX-K2
•
Modem units with part numbers starting LSX-L2
•
Modem units with part numbers starting LSX-M2
The LSX series links comprise two Modems linked by two fibre optic cables.
The fibre optical cable is single mode fibre type depending on span length, and uses FC/APC or
E2000/APC (OEM module only) type connectors.
Care of Fibre Optic Connectors
NB: When the fibre optic cables are not connected, it is essential that the cable and equipment
connectors are protected by the dust caps provided with the system. Failure to do so may result in
damage to the fibre ends, which are critical to the system performance.
2 Setting up and Understanding the Modem
This section describes the connections between your Serial Digital Fibre Optic Modems, and the
operation in a system.
Please read fully document Lxx-HB for information on installing your
ViaLite
equipment before
commissioning your system.
2.1 Module
Formats
2.1.1 Plug-In Modules
The plug-in modules are designed for use in PPM’s
ViaLite
19” rack chassis. The module is powered
from the rack chassis backplane and all connections are on the rear panel (see below).
Connector A is a DIN 41612 backplane connector providing power, data access and connectivity to the
module alarm outputs.
Connectors B are FC/APC receptacles. These are the optical connections for linking the Modems
together.
