Interface and Adapter Cables Explained . . . We make Cables to connect Transducers and Monitors. Click for a list.

It may help you to know why we make a distinction between Interface Cables and Adapter Cables.  There is a simple reason.  Adapter Cables are short, about one foot long.  Interface Cables are much longer, about ten feet long.  Also, there are other reasons to distinguish between these two types of Cables.

The primary purpose of Interface Cables [Figure 1.] is to connect Transducers directly to Monitors. They must be long enough to reach the Monitor, and are about ten feet long.  There are two types of Interface Cables, the captive type and the detachable type. The detachable type of Interface Cable is generally used with Disposable Transducers.  Some Reusable Transducers also use detachable Interface Cables while others have captive, or non-detachable Cables.  This sometimes causes confusion.  When a Transducer has a captive Cable, it is not unusual to consider the Cable and its connector as part of the Transducer.  To be consistent and avoid confusion, it helps if we share the understanding that an Interface Cable is always required to connect a Transducer to a Monitor, regardless of whether that Cable is captive or detachable.  To say this somewhat differently, it does not matter whether an Interface Cable is captive or detachable, it is still an Interface Cable.  You need one to connect a Transducer to a Monitor.

In contrast, Adapter Cables [Figure 2.] have different purposes depending on the particular application.  They may be connected to the Monitor end of Interface Cables so Transducers can be used with Monitors that require different connectors or wiring than that provided by the Interface Cable.  If your Transducer has a captive Interface Cable, an Adapter Cable may be the only practical way to connect it to a different Monitor.  Adapter Cables can also be connected and left attached to Monitors so that the Monitors may be used with Interface Cables different than those which would plug in directly.  Using this technique you could make different monitors compatible with existing Interface Cables.  In some situations it is simply more convenient to use Adapter Cables than it would be to use Interface Cables alone. For example, if you have Monitors that you would like to use with Interface Cables for different Monitors, Adapter Cables provide a convenient solution. Similarly, if you have Transducers and Interface Cables for a particular Monitor, Adapter Cables allow you to connect your Transducers and Interface Cables to different Monitors.

Since it is not the purpose of Adapter Cables to extend the length of Interface Cables, we decided that an optimum length for Adapter Cables is about one foot.  Cables that are intended to extend the length of other cables are called Extension Cables, and although we can supply them, they are not discussed here.
