I have some old customer equipment. A PanelView 900 color (2711-T10C9) which has a DH485 Sub D connector communicating with a SLC 5/05 via its serial port. I need to upload/download a program modification to the PV. I don't have an old PIC unit or a USB -> DH485 adapter. An old ATA memory card would work if I had one and a computer with a PCMCIA slot.
That is why I was wondering if I could use the pass-thru feature to communicate to the PV through the SLC via Ethernet and then from the SLC to the PV using DH485. It's been a long time since I tried this. What is the setups to do this? Thanks.
