Hi all,

I have a VantagePro2 with a serial data logger.

The data logger serial port is connected to a Serial-to-Ethernet converter (MOXA NP5110).

Should I use the Vantage serial or ethernet driver?

They are the same driver, but I would try ethernet mode first.

Ethernet mode seems to be working well.

One more question: what is exactly the parameter "tcp_send_delay" used for?

After a packet is sent through the wire, weewx sleeps this long before looking for a response. It takes a bit of time for the Vantage to process the packet and respond.

Ok. So it is a Vantage "feature" and not a TCP/IP one.

Thanks a lot!
