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.
