3.2.1  Setting the Start Address
Each Pelco CM9760-IRC unit requires a six-bit start address. The start address is
configured using the DIP switches on the communication card (see Figure 5: DIP
switches). Each control card occupies one address space. An IRC unit occupies
four address spaces (if there are only two control cards in the unit, it still occupies
four address spaces).
The start address of an IRC unit is set with the DIP switches on the communication
card per Table B.

Unlike an IRC unit, a serial GPI occupies one address space. In the sample system
outlined in Figure 3, the start addresses would set up according to Table C.

start address of the IRC as a whole.
The start  address of each control
card in the unit is set by internal de-
fault.
