Description

The LWDAQ Union provides two RJ-45 sockets to join LWDAQ or Ethernet cables. The A2039A version provides a patch area where we can connect to the eight signals, attach pull-up and pull-down resistors, and cut the signal connections with a scalpel. The A2039B is a more compact version with no such patch area, designed for extending cables that turn out to be too short during LWDAQ system installation. The A3039E is a six-way union with one side shielded connectors and the other side unshielded.
