ZoneLink® is Holjeron’s proprietary control protocol developed to leverage off-the-shelf Cat 5 LAN cable to control a brushless DC motor driven roller. One facet of ZoneLink® is serial command and control protocol called .S. (dot S.)

The ZoneLink® .S protocol uses a serial link to:

• Monitor predictive diagnostics embedded in the Driver Module to flag when a powered roller should be replaced, in advance of the roller failing.

• Set line speed either individually or globally across up to 255 zones.The ZL.S-F32 enables a Windows- based computer to monitor and communicate a .S network using the computer’s serial (RS232) port.
