Thanks !
Those devices connected with the short trunkline are 1747-AIC passive isolators. The setup you have should work find with the PanelView as Node 2 and the SLC as Node 1. The isolators allow for another device to be plugged in simultaneously (like the ancient 1747-PIC, or the decade-old 1747-UIC).
You could also take the cable from the PanelView that connects to the left side 1747-AIC and connect directly to the SLC-5/03's Channel 1 DH485 plug.
If you had a duplicate node number, the PanelView would have given you a message indicating so.
Take a look at the DH485 status LED on the SLC-5/03 and the COMM status LED on the PanelView when everything's powered up and plugged in. A steady green LED means there's DH485 token-passing traffic going on, while a 1 Hz flashing LED means there's no DH485 traffic (thus very probably a cable problem).
