ComTest Picture


ComTest is a passive testing device for RS-422 protocol communications and control circuits. It uses LEDs to indicate correct and faulty cables, port configurations and the presence of data. It can be used as an in-line tester or on an open port or cable.

Being small, only 63 x 33 x25mm, engineers and technicians will find COMTEST indespensible, whether commissioning systems or in maintenance. It is easily carried even in a pocket and should be in every toolkit. Non technical users will find it useful, too. If you have no in house technicians, it's so easy to use that you can check your connections and then report the results to the repair man or call the right service organisation.
