Q: Can you use the Ethernet port, part number "R2" to program PIDs with and what software is required?

A: The Ethernet port "R2 can be used in applications programming PIDs. Ethernet port "R2" is just a pass thru connection for Ethernet cables, 2 female Ethernet RJ45 ports, one on either side. No software is required for our Ethernet port "R2". However if your PID requires software you will need that particular software.
