MARKETING INFORMATION

  • DTE/DCE-selectable, so you can switch between a modem and a printer. There's no need for crossover cables.
  • Safe for use with laser printers.
  • Includes a hardware-handshake lead in each direction for added control.
  • No unintended triggering - no matter what data you're sending.
  • Also available with eight ports.
The integrated Code-Operated Switch, RS-232, 4-Port is an asynchronous RS-232 switch with four subordinate ports and one master port that enables you to switch serial devices with codes.

There's no unintended triggering with this switch - no matter what data you're sending. With an internal DIP switch, you select the arming character to use as a trigger.

You can set each port individually as DTE or DCE. That's handy for switching among modems and printers. And your connection is secure. Once a connection is made, other ports are locked out. (Remember that all ports need to be set to operate with identical speeds and word structures.)

For extra control, there's a hardware-handshake lead in each direction in case a device (or the computer) needs it.

The upgraded switch platform has several new features, including:

  • Integrated transceiver loopback for faster fault isolation.
  • Enhanced front-panel LED display to provide a visual indication of more switch operations, including the status of data activity, switch time, port lockout, and control handshake.
  • Power-on initialization that includes port selection default.
  • Onboard programmable PROM to provide function updates and maintenance via active serial and JTAG connections.
