We have several models of the Rabbit RCM modules in the field. At one facility we have an RCM2200 on the same VLAN and switches as an RCM6760.
Using Wireshark, when monitoring the RCM2200, we can see the proper SYN, SYN,ACK, ACK.
When monitoring the RCM6760, we see the SYN from the software, but get a RST,ACK response from the RCM6760.
We can disconnect the 6760 from the network, connect a laptop directly to the 6760, and the software connects every time. Therefore we know the host application is running and the port is being listened to.
Our customer is desperate for a resolution to this issue. Please advise.
