THVD1400: THVD1400DR transmission distance issue

Part Number: THVD1400

hi,

The customer uses THVD1400DR as the RS485 transceiver, the sending end is powered by 3.3V, the receiving end uses 5V power supply and point-to-point communication. Does it affect the transmission distance?

In order to reduce power consumption, the customer does not want to add matching resistors, the transmission distance requirement is 200 meters. Does not adding a matching resistor affect the transmission distance?

Thanks!
