"1492-CAB025B64", refers to a cable assembly for use with the Allen-Bradley Micro850 family of microcontrollers. The "1492" prefix indicates that this component is intended for use within the Allen-Bradley product line. Following the prefix are seven characters, each of which represents specific information about the cable assembly:
| Character | Meaning |
|---|---|
| 1 | Cable type code |
| 4 | Cable length code |
| 5 | Connector type code |
| 6 | Number of pins |
| 7 | Shielding options |
| 9 | Manufacturer's identifier |
| 10 | Check digit for cable assembly |
In this case, the cable assembly manufacturer is Allen Bradley, so the check digit is calculated as follows:
CHECK DIGIT = MODULO (SUM OF ALPHANUMERIC CHARACTERS)
------------------------------------------------
SUM = 1+4+5+6+7+(10TH CHARACTER FROM LEFT TO RIGHT)=29
MODULE = 29 % 11 = 0
CHECK DIGIT = 0Following the check digit is the actual part number, "25B64". This denotes that the cable has 256 pins and is designed for use with the Allen-Bradley Micro850 family of controllers. The suffix "-XX" indicates a revision level, indicating that the cable was modified at least once since its original release. In summary, this part number implies a cable assembly specifically engineered by Allen Bradley for use with the Micro850 family of controllers, containing 256 pins and featuring some form of shielding.
