Connection Possabilities
The 750 Series Module PCB Operates as an Interface ‘Hub’ on the Addressable 2-Wire Highway.

Device Address Table
Note that one 2-Wire addressable highway running S protocol can support up to 32 modules.
Each module can have up to 8 connected devices. IGD Configuration software is used to configure the
module PCB to switch devices on and off and set addresses (see Tocsin 650/750 Manual). If the
connected devices have already been configured then the base address can be set from which all other
module addresses will sequentially follow. This is described later in this manual. Device addresses
indicated in the table are typical but can be individually set.
