Analog cards store the analog values in addresses 1 through 4. For example, A1 would read Analog One from card A, (assuming that it is an analog card).
Some cards also provide support for reading digital information stored in slots 9 - 12. For digital and pulse cards, the values are read from addresses 1 through 12.
For Radio Interface Module (RIM) cards, the addressing is:
- R1-12 are Digitals
- R13 to R16 are Analogs (if present)
For PCU cards, the addressing is as follows:
- 1-44 are Digital In
- 49-56 are Analog In
- 58-73 are Digital Output
