Model PWS-20P-RETRO
Model PWS-20P-RETRO is designed specifically for use in Heritage Buildings using existing wiring not capable
of RS485. Communication is performed via a proprietary Unipolar Bi-Directional (UBD) low baud rate protocol.
This permits digital control upgrades to facilities that would otherwise be faced with a very expensive wiring
replacement cost!
Minimum of 4 wires required. Maximum distance dependent on wire type and gauge.
Typical 1000' or 300m on #18 AWG wiring.
Model PWS-20P-RETRO Configuration and DIP Switch Settings
Important!
One station in each wiring LAN must be designated as a Main PWS (switch 4 ON). Only one Main Station
per LAN. All Secondary PWS connected to the Main PWS (maximum 14 PWS) must have switch 4 turned OFF.
