RS485-MX16

Description

The RS485 multiplexer „RS485-MX16“ distributes a serial input signal to 16 RS485/simplex outputs, or RS422/duplex outputs respectively. An example application would be the connection of dome cameras, being connected to the controlling device in a star-shaped manner (e.g. SIMATIX NEO II, SIMATRIX 648 II , VM1000, SDC Videoserver, DSU)

The input of the multiplexer can alternatively be controlled with RS232, RS485/RS422 or TTY/CL (20 mA). The multiplexer is designed for single-master/full-duplex operation (RS422, 4-wire). Each one of the connected RS422 devices can send back to the controlling interface. Multimaster and half-duplex operation are not supported. As with RS485, only simplex operation is supported.

The multiplexer is available in 3 variants:

  1. RS485MX16-HS: tool-free connection technology, for DIN mounting rail (TS35)
  2. RS485MX16-MG: tool-free connection technology, in mounting box (IP 66/67)
  3. RS485MX16-SYS: draw-out unit (IEC 60603-2, for integration into SIMATRIX SYS)
