I have a custom DB9 cable that uses pins 2,3 & 5. Can I use this for serial communication from the PC to the (W)CCU?
No. You will need a full 9-pin null cable, since the (W)CCU communication on multiple pins.
Details on the RS232 connector can be found in theInstallation and User Instructions manual for version 3.1x found on the DCN-NG software ISO.
DCN-NG is set-up in a multi-PC environment, all required licenses are installed. When trying to connect to the server from the secondary PC, the Operator Application takes a long time to start and once it does, the screen is simply blank and the server icon mouse-over shows the application is disconnected. When pinging the server from the secondary PC, the ping goes through without issues.
