What does the serial uart labels of di, de,re,and rd represent with regards to ground, rxd, txd, and vcc? thanks for help.

ro: receiver output, re: receiver enable, de: driver enable, di: driver input, all TTL logic level signals. vvc is 5V, gnd is ground, A & B are the differential serial lines

Which resistor do I clip out to eliminate the terminating resistor?

That will be the one marked R7 (120 ohms) which needs to be removed for all drivers except the two on each end of the cable run. There are many images showing this if you Google for "Max485 Chip RS-485 Module".

Do you have a schematic for connecting these to a raspberry pi?

If you Google "Max485 Chip RS-485 Module" you'll find many examples of how to connect to Pi and many other controllers.
