The figures show the maximum number of photocells possible, although a smaller number may be installed; during programming unit IB will
automatically recognise the devices that are effectively connected.
For unit IB to identify photocells connected to bluebus each must be assigned an address in accordance with its specific function in the sys-
tem. The addressing operation is performed by setting up the jumpers as specified in table 3 for each TX / RX pair.
