Yes, pretty much. The master would send with:

int val1 = (map(analogRead(sensorPin1), 0, 1023, 0, 4999));
  RS485Serial.write(lowByte(val1));
  RS485Serial.write(highByte(val1));

And the slave would receive with:

if (RS485Serial.available() >= 2) {
  byte l = RS485Serial.read();
  byte h = RS485Serial.read();
  val1 = word(h, l);
  }
