How to Key the
I/O Module Field
Wire Connection
Use an STB XMP 7800 keying kit to key an I/O module field wire connection. The
keys can be inserted into the desired slots on the module per your keying scheme.
When keying this connector, the key pin from the key pin wheel is pushed into the
field wire receptacle at the front of the module, then the break off pin on the
connector plug is broken off to match. Here are the steps for keying the field wire
connections on your modules:
Step Action
1 To key a field wire connection on your module you will need your keying scheme, a
key pin wheel from an STB XMP 7800 kit (or the keys that came with your connector
kit), access to the front of the module, and the two field wire connectors separated
from the module.
