General Information
The 4900 Commander is a control system developed by R. STAHL TRANBERG AS.
R. STAHL TRANBERG has a long history of designing and manufacturing navigation
lights controllers for medium sized and large vessels. The traditional design principle
has been a direct control of each channel, meaning that the cable for each individual
lantern needs to be laid from the lantern to the actual controller. This is both a costly
and challenging task.
The Commander has been developed with greater flexibility in mind, and in particular
with the objective to avoid pulling each lantern cable into the bridge. The c oncept is
therefore based upon the industry-proven RS-485 network with a number of nodes
connected to this.
A node may in this respect be a control panel, a relay output module, the master CPU
and more. Each node is given a unique address and the corresponding action between
a single button and the panel is defined in the configuration of the sys tem.
