  • Page 22: Electrical Connection

    To connect a standard PC with a RS 232 interface an interface converter RS 485 to RS 232 is required. A converter that has been tested and recommended by Pepperl+Fuchs is manufactured by Telebyte (Telebyte Model No. 285). This can be obtained from Pepperl+Fuchs under the part number "Telebyte Model 285M“.
  • Page 23 In accordance with the RS 485 specification up to 32 stations ("multidrop") can be connected to a up to 1200 m cable (for data rates less than 100 kBaud). Pepperl+Fuchs recommends that this length of cable is not exceeded. Even though problems seldom occur at these data rates, screened twisted two-wire cabling should be used.
