SERIMUX-TERM-CS-16 (Front & Back)

Designed and Manufactured in the U.S.A.

RoHS Compliant Console Serial Port Switch

Features & Applications

The SERIMUX® Console Switch with Terminal Converter combines an ASCII terminal emulator and a console switch and is operated by a PS/2 keyboard and VGA Monitor. The SERIMUX-TERM-CS-16 can be used to to control up to 16 serial devices. The console switch uses menu-driven integrated software. The terminal converter can easily be configured for either RS232-Device control or Telnet communication modes.
  • Connects up to 16 serial devices, including servers, switches, routers, and telecom gear.
  • Provides out-of-band access to network devices (servers, routers, network switches, and any other network devices allowing console operation using RS232).
  • Power cycle without halting SUN host computer.
    • No inadvertent "break" signals are generated to cause unintentional rebooting of SUN computers.
  • Connects to console serial ports using standard CAT5/5e/6 cables and cable adapters.
    • Maximum cable length is 100 feet.
  • Two operator levels (administrator and user).
  • Switching is simplified with programmable device names and menu-driven device selection.
    • All configuration parameters are stored in non-volatile EEPROM.
  • Built-in data buffers save the most RS232 console output from each connected device, which simplifies troubleshooting failures.
  • Gain access to servers without interrupting service to end-users; maintain optimal up-time.
  • Manage server farms or data centers via serial ports and standard external modems.
  • Supports parallel and RS232 serial printers
  • Printer server capability.
  • Converts the RS232 port of a serial device to PS/2 keyboard and VGA ports so the device can be operated by an NTI KVM switch.
  • ASCII text is displayed on the VGA monitor.
  • Supports color display functions in 80 and 132 column mode.
  • 1RU rackmount case is standard.


  • Compatible with any SUN, HP or PC-based headless server.
  • Communicates with serial devices such as routers, bridges, firewalls, and hubs.
Serial Interface
  • 8 or 16 RJ45 EIA-232 serial port connectors.
  • Flow control: Hardware (RTS/CTS), Software (XON, XOFF), both or none.
  • Signals: TXD, RXD, DSR, DTR, CTS, RTS, DCD
  • Data transfer rate: up to 115.2K baud.
  • Supports standard VGA monitor.
  • Female 15-pin HD connector.
  • Female 6-pin miniDIN keyboard connector.
  • Supports standard PC/AT keyboard 101/102 keys.
Communication Ports
  • Local printer ports: One female DB25 Parallel and one male DB9 RS232 port.
  • Serial baud rates: 50 to 115,200bps.
  • Data format: 7 or 8 data bits with or without parity, 1 or 2 stop bits.
  • Serial handshake: XON/XOFF, XPC, and hardware DTR.
  • Communication options:
    • Single RS232 server connection.
    • Up to 12 Telnet sessions to predefined IP addresses.

Use the SERIMUX Terminal Converter to connect multiple devices such as servers, routers, and switches all in 1RU.

Terminal Emulation
