10. Cascading SRPS units
You can cascade up to 16 SRPS units (1 Manager + 15 Slaves). Each SRPS must
have its own unique ID number and the ID numbers must also be in a logical
sequence. The default ID number of the Manager SRPS is 1. The default ID
number of all Slave SRPS units is 16. So to be in a logical sequence where there is
1 Slave, change the Slave ID number to 2. For each additional Slave give it the
next number - ID no 3, then 4 etc.
Changing 1 Slave’s ID number
1. Power off the SRPS Manager and Slave unit.
2. Connect the SRPS Manager to a computer using the Serial cable.
3. Plug a Terminator into one of the SRPS Manager’s iLINK ports and one into
one of the Slave’s iLINK ports. See Figure 12.
