I have two LX200V20 modules connected via a few metres of cable. Packets only go one way - from the computer to the LAN switch. Packets emitted by the LAN switch do not appear at the device (packet count always zero, wireshark shows nothing. I have checked the magnetics and connections at each end, and they appear to be identical. Any ideas?

What do the green and red LEDs indicate - in detail?
I'm trying to get link running between two LX2000V20 modules.
After a short while from power up, the green LEDs come on at both ends - and stay on.
The red LEDs flick briefly - and both ends at the same time - once every couple of seconds.
The Ethernet is not coming up either at the 'switch' end or at the 'computer' end of the link.
If I break the connection between the two units, the green LEDs go out after a few seconds.
If I re-connect, there is a flick on the reds and the greens come back on.
I am unclear - despite having read the so-called design document- whether pin 14 of the module is an output pin - I think it is. I measure 2.0Volts on it.
