In  order  to  communicate  between  various standard  series  ports  of  computers,  external equipments,  or  intelligent  instruments,  we  must convert  these  signals  first.  The  converter  is
compatible with RS‐232C and RS‐485 standard.

It is able  to  convert  RS‐232  signal  to  RS‐485  balanced differential  signal  and  extend  the  communication distance to 1.2KM.It is passive and doesn’t require
