Code-Operated Matrix Switch  

Centralize your switching chores with the flexible, any-port-to-any-port switch.


Extended Double Diamond™ Warranty Available (3 Additional Year)

Product Highlights

  • Shows the current status of all ports to any PC user running terminal emulation.
  • Port-independent selection of speed, flow control, and data format.
  • No "master" port—any port can talk to any other.

  • Further Details

  • Switch is controlled by arming characters.
  • Rackmountable with optional brackets.

    With the BLACK BOX® Code-Operated Matrix Switch, any port can select any other port. Mix and match PCs and peripherals in any combination for maximum flexibility. This flexible switching eliminates the need for a master port. Any of the switch’s ports can communicate with any other port. Also, any two ports can communicate simultaneously. For example, you can use the switch to connect two PCs to either a serial printer, a modem, or a host. As one PC sends data to the serial printer, the other PC can send data to either the modem or the host.

    Each port is set independently as DTE or DCE, so it’s easy to connect a mix of modems, PCs, and other devices. Or you can control a group of industrial devices, like scales or bar-code readers, right from one PC.

    Create transparent links between any two ports. In a transparent link, the Code-Operated Matrix Switch treats the attention character the same as any other data. Therefore, a transparent link is useful if you have an application (such as a graphics application) in which the data mimics the attention character.

    You can consolidate multiple devices that have RS-232 diagnostic ports by using a PC or by using remote access via modem.

    You also get full status information. Automatic notification tells you when your connection is made or, if the port you select is busy, that a connection can’t be made. Any PC user can get the current status of all ports—instantly find out which ports are linked together, the location of transparent links, system activity, and attention characters.

    Shunt jumpers simplify cabling. Use the shunt jumpers to configure each port for either data-terminal or data-communications equipment. No crossover cable is necessary—you only need standard straight-through cabling.

    The optional expansion board almost doubles the capacity of the switch from five to nine ports. And all ports are independent. You can set speed, flow control, and data format for each port.
