Appendix C- Automatic Fail-Over Option
For applications in need of an Auto Fail-Over system, Thinklogical offers a solution to meet this need in
each of our VelocityKVM models. This option features two separate fiber paths for each signal and the
ability to select which of the two paths is the viable path.
The Transmitter and Receiver contain all the same features as the standard VelocityKVM products in
addition to offering a redundant fiber connecto
r (L1’, L2’, etc.) for each standard fiber connector (L1, L2,
etc.). All other features function as in our standard VelocityKVM Extenders.
Example:
VelocityKVM-24WR Transmitter with Automatic Fail-Over
Fiber Connections
L1 and L1' are redundant outputs, transmitting the same video and KMASS data; L3 and L3' are
redundant outputs, transmitting the same video data. The same will apply to any additional video fibers
(L4, L4’, L5, L5’, etc.) used in other models.
L2 and L2' are redundant back-channel KMASS data inputs. There is an internal MUX which selects L2
or L2' data. When the unit is powered on, it will select L2 first (if L2 is active); otherwise, it will select L2'
(if L2' is active). It will only switch from L2 to L2' if L2 is inactive and L2' is active. Likewise, it will only
switch from L2' to L2 if L2' is inactive and L2 is active.

VelocityKVM-24WR Receiver
with Automatic Fail-Over
Fiber Connections
L1 and L1' are redundant video and KMASS data inputs. There is an internal MUX which selects L1 or
L1'. When the unit is powered on, it will select L1 first (if L1 is active); otherwise, it will select L1' (if L1' is
active). It will only switch from L1 to L1' if L1 is inactive and L1' is active. Likewise, it will only switch from
L1' to L1 if L1' is inactive and L1 is active.
L2 and L2' are redundant outputs, transmitting the same KMASS data.
L3 and L3' are redundant video data inputs. There is an internal MUX which selects L3 or L3'. When the
unit is powered on, it will select L3 first (if L3 is active); otherwise, it will select L3' (if L3' is active). It will
only switch from L3 to L3' if L3 is inactive and L3' is active. Likewise, it will only switch from L3' to L3 if
L3' is inactive and L3 is active.
The same will apply to any additional video fibers used in other models.
