Is it possible for the Javelin to talk to a RS485 device without adding a Maxim chip inbetween?

No. You really need a driver ic like MAX487.
Or a simple TTL driver ic with Q and /Q outputs.
If the baudrate is low enough it might work without terminating
resistors which lowers the output currents considerably.
