The serial extension cable (CLC-MON-N9P) is a flexible DB9 (Male) to DB9 (Female) cable for RS-232 connections.
It is compatible with RS-232 connections on interface units based on Pertronic SPIB and Pertronic GPIB boards, VESDA detectors, and many other RS-232 applications.
The CLC-MON-N9P can be used as an extension lead on any DB9 RS-232 circuit, including Pertronic fire alarm control panels.
