The National Instruments Compact RIO chassis comes with 8 slots for cRIO modules. We currently all 8:

Slot Part # Description
1 NI-9853 2-Port High Speed CAN Module
2 NI-9871 4-Port RS485/422 Module
3 NI-9870 4-Port RS232 Module
4 NI-9870 4-Port RS232 Module
5 NI-9870 4-Port RS232 Module
6 NI-9870 4-Port RS232 Module
7 NI-9403 32-Channel Digital I/O Module
8 NI-9403 32-Channel Digital I/O Module

These modules ae configured via the Project Explorer window (e.g. gfip-project.lvproj). Expand the FPGA tab until you see "Mod1", Mod2", etc. Right-click on a module, then select "Properties". These tables sumarize the properties.
