Have been running RS Links PIC/AIC driver through AIC-Net from PC to SLC 5/03_300 Micro Panelview via another AIC-Net and was using 1747-AIC (Link Coupler) to 2 SLC 5/03's on DH-485 network. Now the 2 5/03's w/Link Couplers are 5/04's. How can you connect Link Coupler to 5/04 ? Do you have to ?? Channel 0 on both configured for DH-485. I will "modify" cables as necessary.
