Quick question - do I need to remove the resistor on STTXD if I'm not using TXD?

My hypothesis is that I could make this really simple for myself by just throwing a 10K resistor on RXD from the ID20 chip, since I'm not transmitting to the ID20 (it's like a magnetic card reader, and has no input...just output).

Also make sure that ground is connected between the ID-20 and the
consoleLCD board.
