Internal Serial Bus
The Windsor internal serial bus (ISB) can have up to 4 optional PCBs fitted. The Optional
PCBs are either;
• SmartDial/SmartDial Plus
• 8 circuit Concentrator
• 8 channel TX or relay card
• AV60 audio verification card
When an ISB option board is fitted the ISB link on the main PCB must be moved to the
appropriate position. If this link is fitted incorrectly then all ISB option boards and all keypads
will not function.
Internal Serial Bus
Concentrator
The concentrator connections are shown below with all terminations. End of Line (EOL) and
No end of line (NEOL) ISB concentrator variants are available. The circuit connections are
identical to the circuit connections of an external concentrator of the same type. The address
of an ISB concentrator is programmed from a keypad in the Hardware/ISB menu option. The
address can be programmed in the range 1 up to the maximum specified in the System size
programming option.
