I am trying to connect a PC to an HP3000 DTC 16MX via an NPORT DE-311 in the UK and an NPORT 5610-8 in the US. The NPORT products are serial servers. The problem I have is that I can't seem to get the DTC wired to the 5610-8 correctly. The connection looks like this:- PC ---> de-311 ---> 5610-8 ---> DTC ---> HP The connection works fine from the PC as far as the 5610-8 but I can't get anything between the DTC and the 5610-8. The connection between the DTC and the 5610-8 uses RJ45's. I am told by our American office that they are trying to use a cable with the following pin connections. NPORT DTC 4 ----- 1 5 ----- 3 3 ----- 6 I have checked and these pins look correct to me. Does anyone have experience using serial servers to HP3000's. Any help would be appreciated. * To join/leave the list, search archives, change list settings, * * etc., please visit http://raven.utc.edu/archives/hp3000-l.html *
