Figure 18: Steps to Send a Copy
Provide a serial data connection from decoder A’s KEY_OUT line to
decoder B’s COPY_IN line, and decoder B’s KEY_OUT line to decoder A’s
COPY_IN line.
1. On decoder A, set the LEARN line high and then set the SEND_COPY
line high to enter Send Copy Mode. Next, clear both the LEARN line
and the SEND_COPY line low.
2. The MODE_IND line on decoder A will be set high while data is being
exchanged. The MODE_IND line on decoder B will toggle as each user
profile is being received from decoder A. If a successful copy has been
made, the MODE_IND on decoder B will blink twice.
3. The copied decoder B will only be allowed to learn new permissions
from the copied set of users and activate data lines accordingly. All
other features will be removed from decoder B until its memory has
been successfully erased.
