Technically Speaking

Code-operated switches.

BLACK BOX® Code-Operated Switches enable one device to control up to 64 connected devices, depending on the code-operated switch. For instance, you can use one modem— not eight—to control eight devices. Code-operated switches are ideal for applications that require remote switching for file sharing or monitoring. Use code-operated switches for:

•Remote programming. Call in via remote sites to access servers, logic controllers, or any devices that require programming.

•Diagnostics. From your master control room, you can probe servers and run diagnostics.

Why Buy From Black Box? Exceptional Value. Exceptional Tech Support. Period.

Recognize any of these situations?

•You wait more than 30 minutes to get through to a vendor’s tech support.

•The so-called “tech” can’t help you or gives you the wrong answer.

•You don’t have a purchase order number and the tech refuses to help you.

•It’s 9 p.m. and you need help, but your vendor’s tech support line is closed.

According to a survey by Data Communications magazine, 90% of network managers surveyed say that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—and certainly isn’t worth what they paid.

At Black Box, we guarantee the best value and the

best support. You can even consult our Technical Support Experts before you buy if you need help selecting just the right component for your application.

Don’t waste time and money—call Black Box today.
