Extend Connection
Bus Extension. This connection is used to interface
racks together when using the optional LYNX
control system. This is a simple (and inexpensive)
way to extend the reach of the host RCT 5020
controller into several more racks fitted with RCT
5010 bus expanders. It uses a proprietary LYNX
control interface and this connection is physically
daisy chained between all connected racks.
Connection details can be seen in the table below.
The connection is a 9 pin SubD female connector.
Function and connection information is described
below.

Note. When using this interface all connected racks
must be mounted close together, (preferably with
no space in-between racks), as the distance of this
interface is restricted. Please refer to the R CT 5010
Rack Bus Expander reference manual for more
details on this interface and the cables required.
