Configuring the Island Bus
Auto-Addressing
Introduction | Each time that the island is powered up or reset, the NIM automatically assigns a |
| unique island bus address to each module on the island that will engage in data |
| exchange. All Advantys STB I/O modules engage in data exchange. |
About the Island |
|
An island bus address is a unique integer value in the range 0 through 127 that | |
Bus Address | identifies the physical location of each addressable module on the island. Address |
| 127 is always the NIM’s address. Addresses 1 through 12 are available for |
| addressable Advantys STB modules. The remaining addresses are not used in a |
| basic island configuration. |
| During initialization, the NIM detects the order in which modules are installed and |
| addresses them sequentially from left to right, starting with the first addressable |
| module after the NIM. No user action is required. |
Addressable Only the Advantys STB I/O modules in the basic segment require island bus
Modules addresses.
Because they do not exchange data on the island bus, the following are not addressed:
