I have a SBC that has a RS-485 port. It has jumpers for bias and termination resistors.
I would like to connect one or two led character display units generally no more than 50 feet away. If using one display unit, I will simply connect the two devices point to point. If the installation calls for two display units, I would simply like to put a 'T' connector anywhere from 1 to 10 feet away from the first display to branch to the second. The display devices will be sealed and so I do not want to have to set any jumpers or throw switches and I only want one version of the display.
How should I terminate the display devices so they will work in either configuration? (This is not a one-time deal--there will be multiple installations of the system.)
Thanks,
Dale
