Most  industrial  computer  systems  provide  standard  RS-232  serial  ports  with  limited  transmission  speed,  range,  and networking  capabilities.  The  RS-485  standards  overcome  these  limitations  by  using  differential  voltage  lines  for  data  and control signals. The tM-7520U transparently converts RS-232 signals into isolated RS-485 signal with no need to change any hardware or software. This lets you easily build an industrial grade, long-distance communication system using standard PC hardware. The module provides 2500 VDC of optical isolation allowing you to separate and protect critical segments of the system from the rest of the RS-485 network.

The  tM-7520U  provides  2  modes  of  baud  rate  setting,  one  is  Self-Tuner  mode  and  the  other  is Fixed  baud  rate  mode.  The  Self-Tuner  mode  can  support  Multiple  Baud  Rate  and  Multiple  Data Format. The Self-Tuner design is exactly the same as I-7520 series. The Fixed baud rate mode offers a better quality for data transmission over long or lossy lines or electrically noisy environments.
