RCBus Products

The RCBus specifications can be found here.

There are a number of physical options in common use for RCBus compatible products. These include the following module and backplane types:

Module Type	Bus Row 1	Bus Row 2	PCB Profile	Bus Spec.
*80 pin*	40 pins	40 pins	RCBus	RCBus 80 pin
*40 pin*	40 pins	n/a	RCBus	RCBus 40 pin
*SP 40+*	39 pins	10 to 20 pins	RC2014 Standard	RC2014 Enhanced
*SP 39*	39 pins	n/a	RC2014 Standard	RC2014 Standard
*LP 40*	40 pins	n/a	RC2014 Low Profile	RC2014 Standard

Module type: 80 pin
Two rows of 40 pins, typically with the RCBus ‘medium’ PCB profile, following the RCBus 80 pin specification.
Module type 40 pin:
One row of 40 pins, typically with the RCBus ‘medium’ PCB profile, following the RCBus 40 pin specification.
Module type 40+:
These typically have 39 pins in the first row and between 10 and 20 pins in the second row. They usually follow the RC2014 standard height PCB profile. This type is also known as the RC2014 enhanced bus.
Module type SP39:
These typically have one row of 39 pins, usually with the RC2014 standard height PCB profile. This type is also known as the RC2014 standard bus.
Module type LP40:
One row of 40 pins, typically with the RC2014 low profile PCB form factor.

Backplane Type	Bus Row 1	Bus Row 2	Bus Spec.
*80 pin*	40 pins	40 pins	RCBus 80 pin
*40 pin*	40 pins	n/a	RCBus 40 pin / RC2014 Standard
40+ pin	40 pins	20 pins	RCBus-2014 / RC2014 Enhanced

Modules designed for the 40-pin RCBus (or RC2014 standard bus) can be used with 80-pin RCBus backplanes, but not all 80-pin RCBus modules can be used with 40-pin RCbus/RC2014 backplanes.
