FEATURES
• Functions as a data monitor, displaying
captured data on its LCD screen.
• Acts as a data trap (isolating portions
of your data), a device exerciser, or a
pulse-level voltmeter.
• Performs BERT/BLERT testing and all
RS-232 breakout box functions.
• Sends and captures parallel data.
• Simulates other devices so that you
don’t have to attach them.
Use the Comm Tool 1000 to troubleshoot a variety of applications.
OVERVIEW
The compact, easy-to-carry Comm Tool 1000 can replace
several other devices. It performs many different tests on your
synchronous or asynchronous equipment. Use it to watch your
data, test all affected serial or parallel interface signals, and
find the problem fast.
With this unit, you don’t have to guess what your data
is doing, because you can see it in transit. The Comm Tool
1000 can perform data monitoring by capturing data and
displaying it across its LCD screen.
You can narrow down the search field for an error
condition by trapping data with the Comm Tool 1000
(isolating only those parts of the data that you want to see).
The Comm Tool 1000 performs dual-line data trapping (that
is, it looks for data in both directions).
Quickly analyze a mux or modem’s performance. BERT and
BLERT (bit- and block-error-rate tests) compare a data pattern
received from a device to the device’s normal data pattern.
Check printers‘ and peripherals‘ performance. The Comm
Tool 1000 acts as a device exerciser: Send a data stream to
a device and then analyze the device’s output.
Resolve RS-232 or parallel cabling problems fast. When
you use it as a breakout box, the Comm Tool 1000 can isolate
faulty pins. When you use it as a cable tester, it can isolate
breaks in continuity.
Test setup is easy with the Comm Tool 1000’s smart menus
to guide you. And you can permanently store the test setups
and messages you use most in nonvolatile memory.
Versatile without being cumbersome, the Comm Tool 1000
comes in an attractive carrying case that has ample space for
the unit’s power supply, manual, and other accessories.
Using the Comm Tool 1000, you can detect numerous
problems with your equipment. For example, suppose that
some terminals stopped working with the host after you
installed multiplexors. BERT and BLERT tests with the Comm
Tool 1000 show no problems with the muxes, but when you
break out RS-232 signals, you discover that some new mux-to-
terminal cables are bad.
Or, maybe the printer on the third floor is “acting really
weird.” When you exercise it with the Comm Tool 1000, you
don’t see anything unusual. But by monitoring and trapping
data, you discover that form feeds and other control codes
are coming from somewhere. A few more tests reveal that
a spooler is improperly configured.
