Resetting SNIB3 Encryption Keys
After Velocity creates the encryption keys required for secure Host-to-SNIB communication, it continues to use those keys. If for some reason you need to change these keys, there are several ways to do it.
After you have reset the SNIB3’s encryption key to its default value (by setting SW2-1 to ON, recycling controller power, then resetting SW2-1 to OFF), you must perform the following steps to assign a new key:
In the Velocity Administration system tree, expand the DIGI*TRAC Configuration system folder until the master SNIB3 port you require appears.
Right-click on that SNIB3 port, and select Properties from the pop-up menu.
On the resulting Port Properties dialog, check the box for the ‘Reset encryption’ option, and then click OK. This resets the encryption key at the Velocity host.
