About the DB9-DB9 Extension Cable
What can you use it for? The 3 meter DB9 (male) to DB9 (female) CAN bus extension cable is great for connecting multiple CAN nodes in a system.
In particular, you can use it to connect a CLX000 to an existing CAN bus system - e.g. in difficult-to-reach locations.
Further, the cable is non-terminated, allowing you to combine multiple cables into large CAN bus systems. The DB9 pinouts are according to CiA 303-1, meaning that the cable can be used with any of our CAN loggers, adapters and DB9 accessories - as well as most other CAN tools on the market.
When Do You Need the DB9-DB9 Extension Cable?
Below is an example where the extension cable may be relevant:
Machine in Hard to Reach Location
Need to log data from less accessible machinery?
Sometimes you may need to frequently collect your CAN bus data from a difficult-to-access machine. Here, using one (or multiple) DB9-DB9 extension cables can greatly reduce the effort involved in retrieval, providing quick access to connecting/disconnecting your CLX000 CAN logger. It's also useful in case you need to stream real-time CAN data from e.g. machines, test benches or similar while being in a different room entirely.
Note of course that the maximal bit rate falls as you extend the cables.

When the length of the CAN bus system is extended, there is an increased propagation delay. For signaling at 1 Mbps, the maximum cable length is 40 meters to be compliant with the CAN bus standard, which specifies a maximum propagation delay of 5 ns per meter. For details, see this NI article.
