RS232/422/485 optical converter

BS-MC-90 is optical converter of RS232/422/485 serial interface. Converter allows connection of RS232/422/485 serial interfaces over fiber links with the maximum distance of 100km and provides complete isolation between devices and resistance to disturbance occurring along transmission path. Depending on the specific versions, device can be connected using multi-mode or single-mode fiber.

BS-MC-90
  • Connection of RS-232/RS-422/RS-485 serial interfaces over fiber link
  • Configurable serial connection: RS232, RS422, RS485, configuration through DIP-SWITCHES
  • Protocol transparent, up to 1 Mbit/s (RS485) or 460,8 kbit/s (RS232) transmission speed
  • Available optical interface: 850/1310/1550nm, MM/SM, WDM/CWDM
  • Power supply: 6 - 60V DC

BS-MC-90 provides fully transparent operation. Each serial interface is sampled with a frequency of 10Mhz, allowing on data throughput of the RS to 460,8 kbit/s (RS-232) and 1 Mbit/s (RS-485/RS-422). Delay introduced by single converter is below 400ns (for RS232) and 220ns (for RS485). RS485 ports can be set up for 2-wire or 4-wire. Serial interfaces can be configured through DIP switches. BS-MC-90 is able to convert RS interfaces, enabling connections of devices using different interfaces, for example one using RS232 and the second one using RS485 serial interface.

The BS-MC-90 converter is supplied with direct current source, with rated voltage value within the range of 6-60V. The direct voltage may be supplied from an external adapter in case of AC voltage or directly from station power supply. BS-MC-90 is also available in industrial version with extended temperature range, designed for operation in harsh environment. Device can be mounted directly on the DIN rail.
