Point-to-Multipoint Analog System

Unlike the discrete versions, the system must be configured for where specific inputs and outputs are directed. Each unit is normally factory configured and designed to interface with the specific system. Alterations to this configuration are possible using an accessory cable and jumpers and software provided by Data-Linc Group. Reconfiguring the units requires the removal of the cover and uses a custom serial data cable connected to a computer. The reconfiguration of the Master and Remotes should normally be left to qualified personnel or performed under Data-Linc Group supervision

Factory Configuration Process

At the factory, each remote unit is given an address, which is zero (0) to seven (7). Each unit is then programmed for a specific number of analog inputs and outputs, which should to be predetermined prior to sale. Also consider if the system is to be expended in the future. Note that any system will have one Master and a maximum of 8 Remotes.

Limitations of the Configuration Process

Each master unit has eight analog inputs and eight analog outputs. These inputs and outputs can be spent in a variety of ways when configuring a multipoint system. Note that with analog operation, each remote unit’s input corresponds with a specific master output. Two remote units cannot share the same inputs and outputs as with the discrete section. The following is a sample diagram of a point to multipoint configuration.
